About

Copper-Lead-Zinc ores

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.
