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.

The decrease in surface hydrophobicity of pyrite particles during grinding is mainly due to two factors: (1) oxidation of pyrite surfaces by dissolved oxygen or Fe 3+ ions and (2) precipitation and adsorption of iron hydroxides/oxyhydroxides onto pyrite surfaces derived from grinding media as a result of galvanic interactions. It is generally ...
