Lead-Zinc ores

The copper ions replace zinc atoms on the sphalerite surface creating a pseudocopper mineral surface coverage on the sphalerite which is then collected using copper flotation type collectors. Because most of the iron sulphides also report to the lead flotation tails and so feeds the zinc flotation circuit, typically lime is used to raise pH for ...

Copper extraction

Supergene sulfide ores rich in native copper minerals are refractory to treatment with sulfuric acid leaching on all practicable time scales, and the dense metal particles do not react with froth flotation media. Typically, if native copper is a minor part of a supergene profile it will not be recovered and will report to the tailings.

copper Lead Flotation Separation

Copper Lead Concentrate Separation. The separation of copper-bearing from zinc sulphides is effected by two-stage selective flotation, the zinc minerals being depressed and the copper minerals brought up in the first stage with reagents similar to those required in the lead flotation section of a lead-zinc plant; the zinc sulphides are floated in the second stage in the ordinary way.
