Chalcopyrite is the most common and usual copper mineral; the other minerals have been chalcocite, covellite, bornite, which are all copper and copper-iron sulphides while enargite, tetrahedride and ...
Read More2021-10-28 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.

Read MoreThe beneficiation of complex sulfide ores containing copper, zinc, iron and other minerals is generally done by a differential flotation method consisting of two principal steps: in the first step, the copper minerals are floated and sphalerite, pyrite and gangue are depressed with slaked lime, sodium cyanide and zinc sulfate to form a sink; in ...
Read More2011-11-1 Refractory copper ores (CROs) in central Africa contain copper minerals that are locked up in a micacious solid matrix or associated with carbonate, sulfide and phosphate minerals. Several researchers have reported that the recovery of copper from CRO material by an acid-leaching process is not economically feasible, due to the presence of excess gangue-acid-consuming minerals such as

Read More2014-12-31 Abstract. Froth flotation is a mineral beneficiation process implemented in the recovery of valuable minerals from unwanted gangue material. Copper sulphate is used as an activator in the flotation of base metal sulphides (BMS) as it promotes interaction of collector molecules with the mineral surfaces.
