Benification Of Oxidized Copper Ore

A review of the beneficiation of copper-cobalt-bearing

2019-11-1  Low-grade ore deposits are of increasing interest in mineral processing owing to dwindling resources of high grade, easily exploited ores. For Cu–Co ores in the DRC, oxidised ore deposits have historically been the main source of Cu–Co as they are relatively simple to process, mainly by leaching/solvent extraction/electrowinning.
