Lead Zinc ores Danafloat Home

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

This flotation step is conducted at alkaline pH. In the case where galena is floated and the copper minerals are depressed, copper depression can be achieved by using sodium sulphide, hydrosulfite, lime, cyanide, zinc cyanide and/or ferricyanide complexes. Selection of flotation reagents and frothers is an important, even critical, consideration.
