The accelerating increase in global demand for copper, zinc and lead poses a challenge for mining operations: increasing their efficiency and productivity to meet the demand while ensuring their profitability and sustainability. Sensor-based ore sorting can be an invaluable asset for optimizing the process and achieving this goal.

Quartz is one of the most common minerals, but it doesn’t exist in high purity in nature: the challenge for mining operations serving the metallurgical stone industries is to reliably deliver quartz of consistently high chemical purity.

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 Sorting Mining is pleased to announce one of the largest diamonds in recorded history, an unbroken 1,758 carat stone, was recovered by TOMRA XRT sensor technology commissioned by Lucara Diamond Corp at its Karowe Mine in Botswana.
