1120· Concentrator Operations. The ores received into the plant, after conventional washing, crushing and grinding, are subjected to differential flotation for the recovery of sulphide copper mineral for smelting and oxide (or nonsulphide) copper minerals for leaching. Sources of feed materials to the concentrator are: (a) Nchanga Copper Mining Bulk Ore Sorting Thermo Fisher Scientific ZA,Crushing and milling account for just over 50% of copper mine site energy consumption 3 making them a primary target for cost reduction. The goal is to grind the ore just enough for optimum copper mineral liberation in the froth flotation plant circuit. Undergrinding reduces recovery; overgrinding reduces throughput and wastes energy.
