hi All, Can anyone advise me if Guar gum can be used as a depressant in flotation in Gold mine processing? Guar gum is an effective depressant for talc but also depress pyrite. Is there a way around not to depress pyrite?

Copper sulfate is one of the reagents in Zinc flotation. Zinc sulfate is present as an impurity in Copper sulfate solution. Does this impurity have any negative effect on zinc recovery?

Maybe a lot, maybe nothing. Depends on your ore, your other reagents, and a lot of other things. You have to run lab & pilot plant tests to tell.
