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.
