Copper Mining | Bulk Ore Sorting | Thermo Fisher Scientific - CL
The goal is to grind the ore just enough for optimum copper mineral liberation in the froth flotation plant circuit. Under-grinding reduces recovery; overgrinding reduces throughput and wastes energy. Real-time particle size analysis in slurry is the key to effective grinding control in finer particle sizes prior to froth flotation.
