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

2021-10-28  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.

Hydrometallurgy - an overview ScienceDirect Topics

Copper-containing percolate is recovered for recirculation and eventual metal recovery by pumping this solution from lower galleries of the in-place leaching zone. This method may be used for low-grade zones of an ore body that is loosened in place, or for spent ores which have been returned to the mine cavity for disposal.

The stepwise dissociation of cyanide from copper-cyanide complexes can also be used to leach gold from a variety of oxide and sulphide ores. The copper cyanide's fourth ligand readily dissociates at low cyanide concentrations for use in gold leaching.
