How to Process Copper Ore: Beneficiation Methods and ...

Jul 12, 2021· Copper ore beneficiation methods Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.
