Milling Of Copper Processing Cu Pb Zn
CANATUAN CU/ZN FLOTATION METALLURGY
The nature of Canatuan sulphide deposit allowed the staged processing of the ore from high Cu-low Zn ores to low Cu-high Zn ores. Due to this mineralogical stratification, emphasis on the high Cu-low Zn ores was set for the initial 1-2 years of operation. This provided some time to gather enough plant data
