Abstract The current state-of-the-art of chloride hydrometallurgy for treatment of complex sulphide bulk concentrates is reviewed. General considerations regarding the various flowsheet steps are examined and options discussed. Then, individual flowsheets are presented and discussed. Finally, the forward prospects for chloride hydrometallurgy for treatment of complex sulphide bulk concentrates is considered and conclusions drawn concerning the likely application of this technology in the future.
Keywords: Chloride hydrometallurgy, Complex sulphides, Leaching, Metal recovery, Solvent extraction.
