Copper complexes that can be present in cyanide liquors include Cu (CN) 2 , Cu (CN) 3 2 , and Cu (CN) 4 3 with the proportions dependent on the pH, copper concentration, and free cyanide concentration. The main issue facing the process engineer is the fact that minimization of cyanide consumption is favored by the formation of species with a low coppercyanide mole
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.
