Tomra - Tomra Sorting Mining (gruvedrift)


For mange er kanskje Tomras virksomhet innen gruvedrift ikke veldig kjent?

Har skrevet om dette på andre tråder. Bl.a. er de aller fleste av de største diamanter som er funnet i verden de senere år, funnet ved hjelp av Tomras teknologi. Og i Australia tyder mye på at et suksess-prosjekt er under oppseiling. Testing indikerer her at utvinning av vedifullt litium fra gammelt gruveavfall (!!!) ved hjelp av Tomras teknologi vil være drivverdig.

Uansett, en ny suksesshistorie ser ut til å være under oppseiling i samarbeidet med australske Mustang i Mozambique hvor Mustang satser på å utvinne Vanadium og Grafitt. Har også nevnt dette prosjektet på forumet før, men nå foreligger testresultater. Tomra står for sample-testinger og disse lover godt. Et fullskala prosjekt her vil nok gi pene inntekter til Tomra-kassen. Spennende!


Positive ore test results at Mustang’s graphite-vanadium project

By Meagan Evans. Published at Jun 12, 2018, in Juniors

Mustang Resources (ASX:MUS) has informed the market it has received strong results from preliminary ore sorting testwork conducted on drill core from its Caula Graphite-Vanadium project in Mozambique.

The testwork demonstrated that the Caula ore is highly amenable to sensor-based ore sorting, showing that an ore sample with no visible waste could be split into high-grade and low grade streams.

Both X-Ray Transmission and Conductivity-based (EM) sorting were evaluated through testing, with the EM sorting producing the best result for MUS.

...

The preliminary ore sorting test work was conducted by specialists TOMRA, at its Test and Demonstration Centre at Castle Hill, NSW Australia.

In short, the tests found that in a full-scale mining operation, EM sorting would efficiently reject barren waste with minimal loss of graphite or vanadium values; successfully split a moderate-grade ore sample with no visible waste into high-grade and low-grade fractions; and, the potential to use ore sorting to upgrade graphite and vanadium grades.

It should be noted it is still early stages here, so investors should seek professional financial advice if considering this stock for their portfolio.

The results demonstrate the potential to increase production rates without increasing the plant size and to reduce operating costs. With such strong results, TOMRA has recommended a larger-scale formal test work program.

TOMRA has an extensive record in the mining industry relating to sensor-based sorting installations operating at feed rates ranging up to several hundred tonnes per hour, with full automation and thus very low costs per tonne processed.

Lepidolite Hill waste will not be wasted

LITHIUM Australia will use mine waste from Lepidolite Hill to feed its proposed large scale lithium processing pilot plant.

Future Of Mining > Innovation 30 August 2018


The technology developer has been given Department of Mines, Industry Regulation and Safety approval to remove excess tonnage from mine dumps at Lepidolite Hill, which is in Western Australia's Goldfields.

While Lithium Australia is authorised to take the waste, approval to recover lepidolite (lithium mica) is still pending.

The company worked out a way to separate lithium micas in April at TOMRA's facility in Sydney, by using an X-ray transmission ore-sorting system.

The separated mica will be partitioned into a concentrate stream and transported to the proposed large scale pilot plant.

Lithium Australia managing director Adrian Griffin said picking up approval for excess tonnage advanced the vision to produce lithium-ion batteries from mine waste.

NEW TOMRA X-RAY SORTER A GAME CHANGER FOR MINERAL PROCESSING

The contribution of X-ray ore sorting to the efficiency of mineral processing is growing, and TOMRA’s new COM XRT 2.0 sorters are taking the value added by this technology to another level.

28 September 2018

This upgraded model features higher belt speed and throughput, which translate directly into increased productivity in mineral processing. It also offers increased wear resistance and longer component lifetime, with quick and safe maintenance through providing easier access to replaceable components.

Ines Hartwig, Product Manager at TOMRA Sorting Mining, emphasises that the valuable experience gained over the past fifteen years, through monitoring and maintaining the TOMRA COM XRT units operating in the field, has been incorporated into the design of the TOMRA COM XRT 2.0.

“Our sorters have been operating under harsh conditions in both hot and cold climates, sorting wet and dry feed across a wide range of commodities,” says Hartwig.

Nettstedet goldseek.com som beskjeftiger seg med gruvedrift, er naturlig nok mye bedre kvalifisert enn meg når det gjelder å vurdere betydningen av TOMRA COM XRT 2.0. Legg også merke til uttalelsen fra Tomras Harald Henriksen.



TOMRA’s new COM XRT 2.0 could be a game changer for mining and for TOMRA too. TOMRA is one of the few publicly listed companies that sell these high-tech sorting machines for mining. These machines offer a rapid way to separate waste from ore as the material leaves the crusher circuit. The rejection of waste material from entering the milling circuit offers companies a way to process more materials in a more efficient, compact plant. In addition to its mining capabilities, TOMRA’s sorting machinery has gained attention from the European Commission which intends to use the machinery to sort plastic and aid in environmental clean-up efforts. “We have enormous potential to secure a more sustainable world for future generations,” says Harald Henriksen, head of TOMRA Collection Solutions. The company hopes to hire 2,000 new employees globally over a five-year period as their growth trajectory increases.

Nok en fersk nyhet om stor suksess for Tomras sorteringsteknologi for gruvedrift. Som dere kan lese, opplever Newcrest Mining helt enorme resultatforbedringer takket være Tomras teknologi og ser store muligheter!



Newcrest Mining after Telfer profitability jump with ore sorting technology

Posted by Daniel Gleeson on 29th October 2018


Newcrest Mining has confirmed ore sorting technology is one of several innovations it is currently investigating at group level to increase profitability and build on its substantial resource base.

The gold and copper miner’s technology and innovation team spoke at length at the company’s recent investor day about how new developments could enable the miner to produce more, lower costs, increase mine lives and improve safety across the group.

Next generation caving and hydrometallurgical processing, plus robotic mining, was part of the company’s five breakthrough strategies target by 2020, as was selective processing and what it called “sustainable mines”. The latter could see an increased focus on mine electrification and the use of renewable energy.

X-ray ore sorting tests carried out by TOMRA on the company’s Telfer operation in Western Australia had already shown impressive results, according to Executive General Manager of Gosowong and Telfer, Phil Stephenson.

Results to date indicated ore sorting could triple the grade and recover nearly 80% of the gold in the scats stream, according to Stephenson.

Over three months from August, 100,000 t of feed had been tested in a >160 t/h pebble sorting circuit at an average gold and copper feed grade of 0.18 g/t Au and 0.04% Cu. Some 79% of gold and 60% of copper had been recovered with a mass recovery to product of 26% and product grades of 0.56 g/t Au and 0.08% Cu, according to Newcrest.

Following these results, feasibility work had already commenced to design and install a full-scale plant at the scats stream expected to increase overall gold recovery at Telfer by 2-4%, Newcrest said.

And, Stephenson admitted the company is already weighing up the use of this technology on Telfer ore, with a sample from the West Dome open pit recently sent off for testing.

Stephenson didn’t want to say too much on the results, but indicated they had “exceeded our expectations”.

“If we can get this to work at the front end, we could go from two [processing] trains to one,” he told investors last week, adding this would take a big chunk out of the operation’s cost base.

The ore from the Telfer mining operations is processed by a large, dual train, communition circuit followed by flotation and cyanide circuits, which produce gold doré and a copper-gold concentrate. In the financial year ending June 30, 2016, Telfer produced 462,461 oz of gold and 18,940 t of copper.

Should the technology prove worthwhile at Telfer, expect Newcrest to look to apply it elsewhere across its operations.

TOMRA X-ray sorter a game changer for minerals processing

December 4, 2018


Sensor-based solutions specialist TOMRA Sorting Solutions is officially launching the latest upgrade in its ore sorting equipment range – the TOMRA COM XRT 2.0.

It features higher belt speed and design capacity, as well as a heavy duty mining design and better accessibility for maintenance work.

This article first appeared in Mining Review Africa Issue 11 2018

According to TOMRA Sorting mining product manager Ines Hartwig, the improvements in the new model are based on the successful track record of the TOMRA COM Tertiary XRT sorters on multiple sites across six continents.

“Over recent years, our sorters have notched up more than half a million operating hours under harsh conditions ranging from arid deserts to arctic environments, with both wet and dry feed,” says Hartwig.

“The TOMRA COM XRT 2.0 is our flagship machine that will deliver significantly increased productivity to the resources sector.”

“Separation performance is central to the value added by these machines,” TOMRA Sorting mining business development manager, PhD. Christopher Robben continues.

“The higher the separation efficiency, combined with more tonnage and improved uptime, the more value is added to the customer’s mining and processing operation.

"The higher capacity means fewer sorters will be needed to do the job, reducing the amount of auxiliary equipment required to charge and discharge; ultimately resulting in a smaller overall footprint with less steel work.

"Efficient and high-volume separation is therefore a lever to reduce the total capital and operational expenditure of a sorting plant.”

Key features of the upgraded design include increased wear resistance and component lifetime, with improved mean time between failure.

The mechanical platform of the TOMRA COM XRT 2.0 was also redesigned for safer, simpler, quicker and more ergonomic maintenance, by providing easier access to all relevant components.

“The separation chamber, in-feed chute, belt and air system components are all easy and quick to access, making the maintenance stops more efficient and giving the unit high availability,” Hartwig says.

“Modular wear components also enable safe and ergonomic manual exchange in the shortest possible time.”

She highlights the increased speed of the belt from 2.7 to 3.5 m/sec, as well as the more powerful X-Ray system which allows sorting of particle sizes due to better X‑Ray penetration.

With higher levels of belt occupancy, facilitated by improved data processing, the particle size of the feed can also be increased, thereby raising the machine’s capacity and creating a new industry benchmark.

Depending on the material, the TOMRA COM XRT 2.0 can accommodate up to double the maximum size of the previous TOMRA model – from 60 mm - 80 mm on the COM Tertiary XRT to between 100 mm and 125 mm on the latest upgrade.

This improvement translates directly into increased capacity at a ratio of 1:1.

“The result is a small plant footprint and low capital costs for mineral treatment projects, which translates into the lowest specific operating costs per tonne,” says Hartwig.

“The higher capacity makes the TOMRA COM XRT 2.0 a particularly valuable proposition for larger mines, as it significantly cuts down the number of machines required. This economises on both capital and operating costs.”

The ejection system is highly selective, using data processing in combination with highly responsive pneumatic-valve ejectors.

Developed in-house, TOMRA’s proprietary data processing pipeline, from sensor through image processing to the valve control boards, has several special features and filter mechanisms which allow precise control of the valves.

The system’s energy efficient design means that it requires only about half of the energy for compressed air when compared to conventional sensor-based ore sorting systems.

Data on the separation efficiency also shows a low misplacement of waste-to-ore or ore-to-waste.

Hartwig emphasises the collective experience behind the development of TOMRA’s technology, including the vital feedback received from partners and customers throughout its installed product base.

“All the experience that we gain in monitoring operating mining installations are incorporated into our new mechanical designs,” she says.

“We learned early on, for instance, that sorters made for the recycling sector do not necessarily fit the purposes of mining processes. The higher tonnages and abrasive materials running through the sorter mean that the design needs to be more robust and must include increased wear protection.”

The end-goal is to keep downtime as low as possible, so the maintainability and accessibility of the main components are also specially adapted for applications in the mining sector, keeping productivity and availability high.

“Every part of the TOMRA COM XRT 2.0 which is in direct contact with the material is now wear-protected, and the tailormade wear protection is easily exchangeable,” she says.

Design development on the new model dates back to 2015, when TOMRA Sorting Solutions participated in the European Union-funded I2Mine project to help realise the concept of an invisible, zero-impact underground mine.

The company’s prototype was designed to withstand the harsh demands of underground mining conditions, while still operating at a high capacity-to-volume ratio.

According to Robben, a pilot installation at the New Boliden mine in Sweden showed that TOMRA´s sorting solution could lead to an increased productivity of 12%, while removing low grade material before truck transport and milling operations.

“This directly reduces specific energy consumption and carbon emissions for both grinding and transportation; a significant contribution to the I2Mine objectives and for the deep underground mine of the future,” he says.

Since proving this ore sorting technology, the company’s milestones have included the installation and operation of its 1 850 tph sorter feed at Ma’aden Phosphates’ Umm Wu’al project in Saudi Arabia, and its 1 000 tph sorter feed at Karowe diamond mine in Botswana.

This is in addition to several smaller units in portable and containerised configurations in many different countries.

Apart from the different climatic conditions which must be endured, these machines sort a variety of minerals from copper, iron ore and coal to industrial minerals, chrome and diamonds.

“The Umm Wu’Al project, one of the largest integrated phosphate fertiliser facilities in the world, is also the largest operating sensor-based ore sorting installation,” Robben says.

“This makes it an important reference site for the TOMRA COM XRT 2.0 machines, which are employed in the plant’s silica rejection stage.”

The plant is part of the Waad Al Shamal phosphate project, a joint venture between the Saudi Arabian mining company Ma’aden, the US-headquartered company Mosaic, and Saudi petrochemical giant SABIC.

The Umm Wu’al phosphate project is part of the development of a new industrial city in the north of the country.

The plant is capable of processing 13.5 Mt of raw material per year, which can be sorted by just nine of TOMRA’s COM XRT sorting units, facilitated by each unit’s operational width of 2.4 m.

“After extensive test work, Ma’aden came to the conclusion that TOMRA’s COM XRT sorters would be the most beneficial solution for its new $560 million processing plant at Umm Wu’al,” Hartwig says.

“The sensor-based ore sorters at Umm Wu’al sort more than 70% of the ROM material by removing flint stones from the phosphate in order to reduce the silica content; by removing this hard waste material, the downstream process can be significantly down-sized.”

This installation removes more than 90% of the chert in the +9 mm fraction, which represents 50% of the plant feed, before the phosphates are fed to the milling and flotation circuit.

It considerably improved the mill performance by reducing the consumption of energy, water and chemicals per ton of final product, which was all achieved with a smaller sorting plant footprint.

At Lucara Diamonds’ Karowe mine in Botswana, two TOMRA COM XRT 2.0 /1200 models are installed in the mega-diamond recovery (MDR) circuit located directly after the primary crusher and ahead of the process plant.

The MDR circuit treats material in the size range between 50 mm and 120 mm.

“This maximises the upfront recovery of exceptional diamonds prior to the comminution processes where diamond damage may occur,” Hartwig says.

“The machine has proven itself through its high availability throughout its first year of operation there.”

Novo has nearly 90% gold recoveries in the Pilbara

Matt BirneySPONSORED
Friday, 1 February 2019 4:50AM


Conglomerate gold developer Novo Resources has generated encouraging gold recoveries of up to 89.4% from mechanical ore sorting trials completed on four bulk samples from its Comet Well project, located near Karratha in the western Pilbara region of WA.

...

The initial bulk samples weighed between about 4 tonnes to 5.5 tonnes and each and were crushed, screened and then tested using a “TOMRA” mechanical rock sorter specifically on the fractions between 6mm and 63mm in size.

...

Mr Humphryson added: “Concentrate grades received from the recent TOMRA mechanical rock sorting trials are impressive, reflecting the capability of the scanning and sorting technology to differentially select gold bearing rock.”

Company's Quest to Become an Established Gold Producer in Australia

Source: Maurice Jackson for Streetwise Reports (2/23/19)

Dr. Quinton Hennigh, chairman and president of Novo Resources, sits down with Maurice Jackson of Proven and Probable to discuss how the road to production looks.

...

Novo has done test work with TOMRA, for example; this was starting in late last year in November. The results that came out are fantastic! We think there is potential to crush up the conglomerate, screen it, of course, but put it through an ore sorting machine, and actually let the ore sorter pick rock with the gold particles.

...

Maurice Jackson: Alright and the second question: "How do you intend to extract the gold?"

Quinton Hennigh: Like the coarse gold is a problem from the sense of assaying but in terms of recovery, it is quite favorable. Gold is dense. One of the easiest ways to treat coarse gold is, of course, gravity recovery, and that's certainly a possibility, but one of the things we wanted to look at was a call it a somewhat portable style of processing, by using ore sorting machines.

These ore sorting devices are skid mounted or they're mounted on a transportable platform. They can be moved from one location to the other. Now why is that important? Well, this is a flat deposit, so if you have something that's long, you know rather than trucking ore from one place to another over kilometers, why not mine process, right on the spot, and then move as you mine the material.

We looked at TOMRA ore sorters starting late last year (click here). We tried ore sorting early in 2017, had mixed results with the Steinert, first looked like it worked great, second rendition didn't work so well. When we went to TOMRA they showed us some reasons why they thought they could improve things dramatically and just recently we published the final data from that.

...

Maurice Jackson: Looking forward, what are the company's goals and objectives for 2019?

Quinton Hennigh: First, at Beatons Creek, which I talked about as being the most advanced project. We have a resource remodel underway right now, this is work that's ongoing and we are expecting some bulk samples back from the project. These are ones we collected late last year. Once we have all that data, which should be available by the end of the first quarter, we anticipate publishing a new, updated resource for Beatons Creek. We are targeting over a million ounces, we'll see if we can get there, I feel pretty confident. Beatons Creek should be a robust deposit. This puts the project in a good path for monetization. Then we will take the next steps of looking at how we potentially develop that project.

Second, at Comet Well and Purdy's Reward, we anticipate doing a level of trial mining this year. We are continuing to evaluate some of the test work around the TOMRA, for example, as a means of processing at Comet Well. I think once we get a full evaluation, and we do have a bit more data we got to get back on that, but once we have a full evaluation of that processing, we'll look at that trajectory. Bear in mind, we also are shooting for that mineralization report and working on a Native Title agreement so that we can convert a lot of that country into mining leases. That's the trajectory for Comet Well and Purdy's Reward.

PRESS RELEASE

Nicola Mining Announces Positive Results on Copper X-Ray Sorting as a First Step to Copper Ore Upgrading

Published: Mar 29, 2019 8:33 a.m. ET


Vancouver, British Columbia--(Newsfile Corp. - March 29, 2019) - Nicola Mining Inc. (NIM)(the "Company") is pleased to announce positive results from Outotec's Initial Inspection Study, in which select material from the terraces and highly mineralized zones at the wholly-owned New Craigmont Copper Project ("Craigmont Project") was evaluated. The test work was conducted at Tomra Sorting's Test Center in Hamburg, Germany. This study successfully demonstrated that the COM Tertiary XRT Sorter can clearly distinguish ore [1] from waste material.

The material used in the Initial Inspection was comprised of 29 representative samples of waste, low-grade ore ("LG ore"), ore, and high-grade ore ("HG ore") (Figure 1). These samples were collected from the terraces and targeted zones that represent ore material at the Craigmont Project.

This study clearly indicates the ability to differentiate, and thus potentially upgrade, copper sulfide material encountered at Craigmont. The conveyor system has a throughput capacity of up to 400 tonnes per hour and can be set up in parallel lines. The Company believes that the ability to distinguish and separate copper sulfides from waste rock is of great significance for monetizing copper contained within the historical mine terraces, which equate to approximately 80-90 million-tonnes [2] , surrounding the Craigmont Mine pit.

Suksesshistoriene bare fortsetter å strømme på når det gjelder Tomra Sorting Mining. Nå er det De Grey Mining som rapporterer om kjempegode testresultater fra sine gullgruver i Toweranna, Western Australia etter at tester gjennomført med Tomras markedsledende sorteringsteknologi. Så altså nok et case hvor det trolig bare er et tidsspørsmål før sorteringsmaskiner fra Tomra bestilles og skipes til gruveområdet.



De Grey Mining completes ore sorting test work from its Toweranna Gold deposit in WA

13:40 07 May 2019

Additional test work will be carried out on a wider range of samples to further assess the grade distribution, crushing parameters and economic viability of ore sorting at Toweranna.


De Grey Mining Limited (ASX:DEG) has confirmed positive results from ore sorting test work undertaken on geological samples from the Toweranna gold deposit within its wider Pilbara Gold Project in Western Australia.

Mineralised quartz and sulphide vein material was efficiently separated from non-mineralised host granitoid and sediments using single-pass laser sorting at a coarse feed size of 20-100 millimetres.

The test work, which was undertaken by TOMRA Sorting Pty Ltd, was completed on five distinct geological rock types from a single drill hole at Toweranna.

TOMRA was requested to assess the various rock types and if feasible to demonstrate that the mineralised quartz-sulphide vein material could physically and efficiently be separated from the non-mineralised waste rock types.

The composite sample was sorted using laser scanning and a second pass of X-RAY Transmission (XRT) scanning was undertaken on the waste product to determine if any sulphide mineralisation remained.

XRT results showed there were negligible sulphide minerals remaining in the waste product.

The evaluation was set to retain any fragments with less than 5% quartz by area.

Notably, the laser scanning, which targets identification and retention of quartz veining, has accurately retained almost all fragments with any quartz veining.

Assays of the material have not been undertaken as this preliminary sampling was designed to provide only rock type characterisation.

De Grey has planned further ore sorting testing to target known mineralised intersections as well as to determine the potential increased grade through ore sorting prior to concentration.

Grade increases are expected with ore sorting as the gold is known to be almost exclusively hosted in the quartz-sulphide veins based on detailed core samples and gold results.

The company considers the results to be excellent and clearly demonstrate the potential to upgrade and concentrate the quartz-vein material prior to trucking to the proposed processing plant.

Test work results provide additional confidence that ore sorting may provide substantial added benefits through enhanced grade increases, improving future economics at Toweranna.

De Grey consideres ongoing conventional metallurgical test work, ore sorting and financial evaluation warranted.

The company's planned activities include finalising metallurgical test work on the purpose-drilled PQ core, which has been well-advanced by ALS Metallurgy.

Elementos reports ‘impressive’ results from performance testing of Oropesa tin samples, progresses with project acquisition

By Imelda Cotton - May 22, 2019


Multi-national, tin-focused exploration company Elementos (ASX: ELT) has completed first phase ore pre-concentration performance testing on a three-tonne bulk sample from its advanced Oropesa project in Spain.

Conducted at the facilities of Tomra Sorting Solutions in Germany, the phase involved the separation of high-density and low-density particles using Tomra’s x-ray transmission (XRT) technology.

The samples were representative of Oropesa’s potential different host rocks (sandstone and conglomerate), ore grade (low, medium and high) and weathering (weathered, transitional and fresh).

Tomra claims XRT makes it possible to obtain a high purity level in sorting materials irrespective of size, moisture or surface pollution level.

“Impressive outcome”
Elementos chief executive Chris Creagh said he was “impressed” with the outcome, with initial visual inspection of product and waste samples indicating good separation and showing that ore sorting could potentially provide significant operational and financial benefits.

“We are very encouraged by the results of our first technical program at Oropesa and while we are still waiting for final assay results, early inspections of the sorted samples demonstrate great potential,” he said.

“A successful program could have a significant impact on the overall design of the Oropesa plant and potentially lower our capital and operating costs.”

The second phase of testing will involve detailed chemical analyses of all product and waste samples to determine the overall performance of the process.

Results for the second phase are expected in late June 2019.

North Arrow brings in Imilingo, TOMRA, Microlithics for modular diamond recovery

Posted by Daniel Gleeson on 22nd May 2019


North Arrow Miners says it has engaged Imilingo Mineral Processing of Pretoria, South Africa, TOMRA, and Microlithics Laboratories of Thunder Bay, Ontario, to investigate modular diamond recovery design options incorporating TOMRA’s X-Ray Transmission (XRT) sorting technology at its 100% owned Naujaat diamond project in Nunavut, Canada.

The engagement is with a view to recovering diamonds greater than 3 mm (nominally >0.5 ct) in size from a diamond recovery plant, it said.

North Arrow is currently planning for collection of a 10,000 t bulk sample from the Q1-4 deposit at Naujaat and, as part of this work, has initiated an engineering design and costing study of a small-scale mobile diamond recovery plant. The purpose of the sample will be to evaluate diamond size distribution and value characteristics, with emphasis on a distinct population of high-value, fancy, yellow to orangey-yellow diamonds that have been identified in the deposit, the company said.

Ken Armstrong, President and CEO of North Arrow, said: “We are pleased to be working with Imilingo, TOMRA and Microlithics to study diamond recovery plant design options for use in our continued evaluation of the Q1-4 diamond deposit.

“Over the last number of years, TOMRA’s XRT sorting technology has changed the diamond mining landscape by providing an XRT sorting solution that improves diamond recoveries while reducing breakage and water use compared to more traditional diamond recovery circuits. We believe XRT sorting technology can also be used for the evaluation of diamond deposits and is an ideal recovery solution for the Q1-4 diamond population.

“Locating a small-scale diamond recovery plant at or near the project site will also reduce costs, improve logistics and increase local employment and business opportunities for the residents of Naujaat,” he said.

Imilingo’s iPlant packages combine XRT solutions from the likes of TOMRA to sort and deliver feed material in a clean and well classified state, Managing Director, Jaco Prinsloo, told IM recently. Microlithics Laboratories, meanwhile, provides a number of diamond-specific services to clients in North America.

The focus on recovery of diamonds greater than 3 mm is an important component of the study, the company said, with a significant amount of the cost associated with processing past Q1-4 kimberlite samples related to ensuring and documenting the recovery of smaller diamonds (down to 1 mm in size).

EXCLUSIVE: The magic of Mothae

Jul 26, 2019


Nestled in a valley close to the top of Lesotho’s diamond-rich Maluti mountains lies ASX-listed Lucapa Diamond Company’s new Mothae mine – the fourth diamond producing mine in the country.

Like its ‘famous’ neighbour Letšeng, the highest US$ per carat kimberlite mine in the world, Mothae comprises a high-value resource that holds the promise of recovering significant high value stones over its lifespan, which after six months of commercial operations (to June 2019) has already proven true.

LAURA CORNISH visited the mine to learn about the operation and its exciting potential.

...

Stones a-plenty

Mothae has already generated significant revenue (US$7.3 million at an average $729/carat) from the first two sales of its rough diamonds at tender in Antwerp. And in May, the mine produced its first +100 carat diamond, just five months after commercial production commenced.

The stone is a gem-quality 126 carat diamond and represents the seventh +50 carat diamond recovered since Lucapa commenced its pre-production bulk sampling programme at Mothae in 2018.

The on-site team place their diamond recovery faith in Tomra XRT sorters, now being operated by Consulmet to ensure the machines work seamlessly at all times.

“We are delighted to have recovered our first +100 carat stone so early in our commercial mining campaign at Mothae, along with other rare Type IIa and fancy coloured gems, and look forward to unlocking the true value of this mine over the next decade and beyond,” Lucapa MD Stephen Wetherall stated upon announcement of the 126 carat diamond.

Scheepers adds: “Considering Mothae has recovered its first big diamond while still mining through the surface, weathered material, this mine’s potential is far-reaching.”

Ore sorting has role to play in ‘Green Mining’ developments, TOMRA says

Posted by Daniel Gleeson on 29th July 2019


TOMRA says its advanced sensor-based sorting technologies can provide mining operations with the energy efficiency and ore recovery benefits they require to reduce their environmental footprints.

The ability to recover valuable ore from even sub-economic deposits or dumps has become increasingly relevant as the energy-intensive mining industry shifts towards a ‘Green Mining’ approach, according to the company.

Tord Svensson, TOMRA’s Head of Sorting Mining, explains: “For a mining company to become more sustainable and profitable, it requires a shift in focus that places more value on potentially limited commodities like water and ore.

“To achieve an environmentally-focused and efficiency-oriented production process – which is integral to Green Mining – it is necessary to implement solutions right from the beginning of the process. This is where ore sorting equipment comes in: using these technologies in the early stages of mining reduces waste material and shrinks the carbon footprint, while increasing profitability.”

TOMRA is a pioneer of sensor-based sorting technologies, offering smart technologies for sorting and separating a variety of valuable substances. Its solutions range from industrial mineral processes to sorting gemstones, ferrous and non-ferrous metals, coal and other fuels and slag metal.

The sensor-based sorting technology not only significantly reduces the amount of energy and water required, compared with more traditional methods such as grinding and dense media separation, but also maximises the efficiency and quality recovery of valuable ores, according to TOMRA.

X-ray transmission (XRT), one of TOMRA’s leading solutions, separates dry material of various ore and minerals based on their atomic density, irrespective of surface properties and thickness. This means it is not necessary to crush or grind every rock into smaller particles, which results in massive savings of energy, water, and their related costs, according to the company.

“Considering that grinding is the most energy-intensive part of the production cycle, as an estimated 50-75% of the energy used in mining is for the liberation and comminution of ore and minerals, this technology can have a significant impact on the sustainability and profitability of a mining operation,” TOMRA said.

Pre-concentration techniques like sensor-based sorting are proven to reduce energy consumption by about half, resulting in a considerable reduction of the CO2 footprint and providing a highly cost-effective solution, the company added.

TOMRA has created a Green Counter on its website that displays the total amount of CO2 reduced through the use of its sorting machines in real time. It uses the smart technology within the equipment, which records the amount of rock sorted and eliminated, as well as throughput and total hours of operation.

“With this data, TOMRA and mining companies are able to calculate the energy in kWh saved by not treating the waste which has been removed by the sorters,” the company said. “The amount of energy saved is converted into CO2 equivalents, which in turn are converted into CO2 metric tonnes.”

Through the use of TOMRA sorting machines, client companies have saved 123,696 t of CO2 in 2018 alone, the company said.

The company concluded: “TOMRA’s sorting solutions have proven to be more than just technological innovation – they are also considered the benchmark for industry standards in both efficiency and sustainability. TOMRA remains committed to evolving its technology with a clear focus towards preserving our shared natural resources.”

1:28 "In every evaluation of new technology we have 'aha' moments for us it was the day we were at Tomra's facility in Germany and saw a rock be sorted on a production scale machine and when we saw how fast it was happening and how it was sorted and rejected, and we were able to pick it up and look at it and realize that this was not just a dream."

2:21 "We're getting rid of material and we're not spending money grinding rock that has no value. We're processing less material so we're able to grind to a finer size and with finer grind our gold recovery has gone up. This has resulted in a an improvements of grade by 10%"

ORE SORTER: Tomra’s advanced technology can make green mining profitable


GERMANY – Tomra’s advanced sensor-based sorting technologies offer mining operations the dual benefits of energy efficiency and the ability to recover valuable ore even from sub-economic deposits or dumps. This has become increasingly relevant as the mining industry – a very large consumer of energy – is shifting towards a green mining approach to reduce its environmental footprint in the face of climate change, while running profitable operations.

TOMRA’s ore sorting technology delivers impressive improvement at Stornoway Diamonds Renard mine

Summary

Stornoway Diamonds is a leading Canadian diamond exploration and producing company. It owns and operates the Renard Mine, in commercial production operation since 2017. It is the first diamond mine in Québec and one of six in Canada. Renard Mine started with an open-pit mine and subsequently opened an underground mine.


The conditions of the mine presented Stornoway Diamonds with particular challenges that required an innovative approach: “Due to the geology of our ore, meaning we produce very high yield, we have lots of material that we need to sort through. At times, we have the possibility of losing some of those very expensive diamonds due to inefficiencies,” explains Marie-Claude Hallé, Marketing Operations Manager for Stornoway Diamonds. In addition, “our ore body at the Renard mine contains a high level of internal and external dilution called country rock, a significant issue for us, as it can make up to 30 to 40% of the feed to the plant. With that comes very, very high energy cost from crushing all this waste material that is not diamond bearing. It causes a tremendous amount of wear and tear on our equipment from screening conveyors, diamond recovery equipment, and on a dollar-per-tonne basis we spend a lot of money processing non-diamond bearing material.”

Stornoway Diamonds needed to find a way to reduce its costs and optimise its operation, and they are fully satisfied with the solution provided by TOMRA: “You have to really envision that TOMRA has actually changed the game in terms rough diamond recovered around the world, and allowed producers to access large exceptional quality goods that perhaps in the past would be crushed to pieces,” states Marie-Claude Hallé.

TOMRA’s solution incorporates ore sorting technology into the mine’s processing plant

TOMRA analyzed the situation and worked closely with Stornoway Diamond’s team to design and install a Kimberlite pre-concentration plant. The specific conditions at the Renard mine meant that the traditional Dense Media Separation method could not provide an efficient and cost-effective solution. It required innovative approach, which TOMRA delivered, making Renard the first diamond mine to incorporate ore sorting into its processing plant.

TOMRA addressed the mine’s recovery issue with its industry-leading sorting technologies, developing a solution with four key objectives for the ore sorting plant: minimize diamond breakage by removing hard rocks from the crushing plant feed; upgrade the quality of the material to the process plant by increasing the proportion of Kimberlite to waste rock; reduce the energy required for crushing by removing the harder rocks; and improve circuit efficiencies throughout the plant.

TOMRA’s solution features five PRO Near Infrared (NIR) sorters in its ore sorting circuit. This technology is particularly well suited to enable discrimination between the various ore and waste materials that need separation at the Renard mine, based on their different chemical composition.

TOMRA also included in a COM XRT 2400 sorter, which uses X-Ray Transmission technology to separate material according to its specific atomic density, in the plant’s large diamond recovery circuit.

Ore sorting technology delivers dramatic improvements

“The TOMRA solution we have in operation has offered us a very low-cost, efficient reliable means of recovering our coarse diamonds without inefficiency, without causing diamond breakage,” comments Marie-Claude Hallé. “It’s a very neat way to get those diamonds out of the Kimberlite at the very early stage of the process. We reduce our power consumption cost, we reduce our wear and tear on material. We are still optimising this unit, and we feel there are even more benefits to come in terms of how it helps enhancing the overall recovery of our diamonds.”

Geoffrey Madderson, Diamond Segment Manager at TOMRA concludes: “The implementation of this plant proves that TOMRA waste sorting technology can successfully be used to upgrade lower grade ROM and that Sensor-based Sorting can be used to further improve value recovery for our clients on lower-grade resources.”

The integration of the ore sorting plant into the main processing plant was completed smoothly, with TOMRA’s full involvement in the ore sorting plant design. TOMRA also had a team onsite for the first three months of operation to ensure a seamless transition, and will continue to provide ongoing support for the entire life of the equipment.

“We chose TOMRA because we find TOMRA’s approach to problem solving to be very innovative,” adds Marie-Claude Hallé. “We see them as a solution provider that thinks outside the box, that doesn’t always come with ‘here’s the off-the-shelf solution to your problem’, but in fact engages with us and looks at what are the best possible options. In fact, it will develop technology if needed to address those specific problems. We always have outstanding service as well, from TOMRA technicians, from engineers, from every aspect of TOMRA Sorting.”

Reduction of waste and carbon footprint

Tomra's advanced classification technologies make a profitable 'green mining' a reality

Editorial Interempresas 03/09/2019


Advanced sensor-based Tomra technologies offer a double advantage for mining: high energy efficiency and the ability to recover valuable minerals even from depleted deposits. This fact is becoming an increasingly important issue since mining, a large energy consumer, is adopting a 'Green Mining' or 'Sustainable Mining' approach that seeks to reduce its environmental footprint and fight against climate change, without lose profitability in your activity.

Vista Gold Mt Todd PFS points towards use of ore sorting, fine grinding

Posted by Daniel Gleeson on 11th September 2019


Following extensive metallurgic test work carried out over the past year, Vista Gold looks like it has settled on a flowsheet for its Mt Todd gold project in the Northern Territory of Australia that includes ore sorting and the selection of the FLSmidth VXP mill as the preferred fine-grinding mill.

The company detailed this in an updated prefeasibility study (PFS) for the project, which factored in the results of metallurgical optimisation test work, a redesign of the fine grinding circuit, construction and ramp-up schedule changes and a comprehensive review of all aspects of the project.

The process improvements resulted in improved projected gold recovery and increased estimated gold production at Mt Todd, Vista Gold said.

According to the PFS, a 50,000 t/d operation at Mt Todd could see the operation produce 413,400 oz of gold over the life over the 13-year mine life at average all-in sustaining costs of $746/oz.

The estimated initial capital requirement came in at $826 million, with the project offering an after-tax net present value (5% discount) of $823 million at a $1,350/oz gold price and a $0.70=A$1.00 exchange rate.

In the company’s metallurgy, processing and infrastructure section, it detailed the processing side of Mt Todd, saying that recent metallurgic test programs had confirmed the efficiency of ore sorting across a broad range of head grades and the natural concentration of gold in the screen undersize material prior to sorting. The company carried out such test work at TOMRA Sorting Solutions in Germany, where two-stage (X-ray Transmission and laser) sorting tests were completed using production-sized and commercially available equipment.

It also said such test work had confirmed the efficiency of fine grinding and improved gold leach recoveries at an 80% passing grind size of 40 microns, in addition to the selection of the FLSmidth VXP mill as the preferred fine-grinding mill.

The company previously sent samples to Core Metallurgy Pty to obtain fine grinding data simulating grinding in the horizontal IsaMill and to the FLSmidth Minerals Testing and Research Center to obtain data simulating grinding in the vertical VXP Mill.
