Pre-concentration by Bulk Ore Sorting (BOS) has gained interest in the mining industry over the past few years due to its environmental and economic benefits. The BOS method is utilizing reducing natural rock heterogeneity in separating the waste rock from the ore before it enters energy intensive grinding and mineral processing process.

Waste rock removal in preconcentration has direct effect on energy consumption in crushing and grinding and chemicals in concentrator. In concentrator waste is separated and goes to tailings pond, however, preconcentration directly reduces the volume of the tailings.
