Copper Sulphate Pentahydrate For Sale In Bulk

In the flotation of sphalerite copper sulphate reacts with the surface of sphalerite resulting in increased collector adsorption and improved flotability Sphalerite is not easily floated by a xanthate because zinc sulphate which would otherwise form is soluble in water and thus wont form hydrophobic film around mineral

Lead

Sphalerite that is rejected into the lead flotation tails is then floated in a second flotation step after activation with copper sulphate 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
