Zinc sulphate heptahydrate is used in base metal flotation as a depressant for sphalerite.
It is also used to depress talc in byproduct molybdenum circuits.
Zinc sulphate can be used to depress sphalerite in flotation in synergy with sodium cyanide.
However, this can only occur at very high pH were precipitation of zinc hydroxide starts presenting a new set of process challenges.
Depression of zinc sulphide from lead and copper sulphide minerals. Can be used alone or in conjunction with cyanide.
Feature:
Zinc sulphate would be ideal were zinc is to be recovered in upstream processing stages as introduction of a wanted element is being made.
