Lead Matt as a by-product of smelting processes, which mainly contains copper sulfide, galena and ferric sulfide, rare components such as indium, silver and others are included.Some techniques,including pyro-refining and electrorefining of crude copper form converting process, oxidizing roosting of lead matt for desulfurization, then separating copper and lead by sulfuric acid leaching, or casting anode plate and extracting copper by electrolysis[12],are conventional treatment processes of lead matt.
