Direct extraction of copper from copper sulfide minerals

Copper is predominantly recovered from sulfide ores by pyrometallurgy an energy intensive process requiring capture and treatment of released SO 2. Whilst some copper ores are amenable to hydrometallurgy, chalcopyrite, the main copper mineral, is challenging to process in aqueous solutions due to surface passivation.

Direct extraction of copper from copper sulfide minerals

Here we provide the first demonstration that electrochemistry in Deep Eutectic Solvents can solubilise and directly recover high purity copper from solution from three copper sulfide minerals: covellite (CuS), chalcocite (Cu 2 S) and chalcopyrite (CuFeS 2). Cyclic voltammetry supported by EXAFS identifies the metal speciation in solution.
