Copper extraction

Concentration. For sulfide ores, both secondary ( supergene) and primary ( hypogene ), froth flotation is used to physically separate ore from gangue. For special native copper bearing ore bodies or sections of ore bodies rich in supergene native copper, this mineral can be recovered by a simple gravity circuit .

Copper Lead Zinc ores Danafloat

Copper Lead Zinc ores. In most cases, lime is used as a pyrite depressant but some operations prefer soda ash because lime tends to depress precious metals. As described in the lead zinc process description, in some instances enhanced iron sulphide depression can be improved by aeration prior to the differential Cu Pb flotation step.

Jul 09, 20190183;32;3 Summary of the copper mineral flotation process (1) Copper minerals (such as chalcopyrite and covellite) that do not contain iron are similar in floatability. Cyanide and lime have weaker inhibition on them, so a large amount of lime can be added to inhibit pyrite in the separation of copper and sulfur without seriously affecting the floatability of copper minerals.
