Flotation of CopperLeadZinc Ores ResearchGate

In the flotation of copper–zinc massive sulfide ores, the flotation properties of copper and zinc are determined by the nature and composition of the ore Selectivity between chalcopyrite andCopperZinc ores Usually chalcopyrite, sphalerite and iron sulphides are present with this type of ore Gangue minerals are typically various silicates, carbonates, and often talc the latter which presents flotation challenges The flotation separation and recovery approach is quite similar to the PbZn sulphide separation process Sphalerite is depressed with zinc sulphate addition toCopperZinc ores Danafloat

CopperLeadZinc ores The CuPbZn separation process is among the most challenging flotation separations primarily because the first step must entail bulk flotation of the two most readily floatable minerals with these two minerals separated in a differential flotation stage In this case, as a general rule because both copper and lead minerals tend to float well, these are14/04/2016· The Problem with separating Copper from Zinc by flotation The treatment of heavy sulphide ores of copper containing zinc and pyrite is often extremely difficult particularly if soluble copper and sulphates are present This is usually the case in ore deposits near the surface or in tropical countries where the annual rainfall is quite high The method of oreChalcopyrite (Cu) Sphalerite (Zn) Separation by Flotation
