TOMRA’s XRT sorting of lumpy chrome ore delivers high recovery rates and cuts costs
Summary
TOMRA’s X-Ray Transmission (XRT) sensor-based ore sorting is an established technology in physical separation that has proved extremely effective in mining operations for a variety of minerals, including chrome. Its benefits are significant: less complexity in the process, considerably lower costs, higher productivity and profitability – and the added advantage of a lower environmental impact.

TOMRA’s XRT technology exceeds expectations in LG6 mine
Engineering and project management company P2E Consulting has first-hand experience of the advantages of TOMRA’s XRT technology in sorting chrome ore at Eastern Chrome mines in South Africa. They were looking for a solution to improve the efficiency of the sorting plant and turned to TOMRA: “We have installed TOMRA sorters on diamond and copper plants in the past and we believe their technology is ahead of their competitors,” states Craig Meadway, Business Development Executive of P2E Consulting.
P2E Consulting commissioned a TOMRA COM XRT 2.0 sorter to replace an existing drum Dense Media Separation (DMS) plant: “The mine used the DMS plant to produce saleable Small Lumpy product from the mine’s LG6 Chromite ROM and dumps at a minimum grade of 38%, but it was very inefficient,” explains Craig Meadway. “The TOMRA XRT sorter has resolved this issue. It is used to upgrade Under Value (UV) material with a head grade of 20% to 28%, to produce a saleable product at a minimum grade of 38% Cr2O3. It does this efficiently and at a low Cost of Production (COP).”
The TOMRA COM XRT 2.0 sorter has exceeded Craig Meadway’s expectations, with grades being achieved in excess of 40% Cr2O3 and mass recoveries of 25 to 30% from scalped waste resulting in Chrome-in-tails as low as 12%: “No other technology has given us such a high recovery rate. Not only that, with TOMRA’s XRT there was no water usage at all and we didn’t need to spend on expensive reagents, so that we are producing Small Lumpy product for approximately 50% of the cost compared to a DMS plant.”
The environmental benefits of TOMRA’s XRT solution were also an important factor in P2E Consulting’s choice of technology: “We are looking to introduce greener technologies into the mining industry. The fact that no water or chemicals are used is a major advantage,” comments Craig Meadway. “Also, South Africa has major power limitations, and the lower energy consumption when compared to DMS is a huge driving force.”
Easy operation and superior support from the TOMRA team
The easy operation of TOMRA’s XRT sorters is a further advantage: “It is very easy to use: once the sorter and feed system control philosophy is set up correctly, the plant runs with very little input from the operators,” explains Craig Meadway.
TOMRA’s collaborative approach and all-round support was also an important factor in P2E Consulting’s decision to turn to them for this project: “We knew from our experience in previous projects that the support from TOMRA is very good, and with the installation of this machine in a relatively new application, it was excellent. The local team has bent over backwards to help us make this happen.”
