Sphalerite is an important Zncontaining mineral and is often found in association with sulfide minerals such as galena pyrite and chalcopyrite [1 2] In industry the flotation method is generally used to achieve the separation of these different minerals [3 4] During separation of sphalerite and pyrite copper sulfate is added to activate the sphalerite and then xanthate is added to make
