WebCopper and nickel sulfides become insoluble and separate as a heavy dross for removal. Copper is lowered from 0.5–3% down to 0.1%. The dross is treated in a small reverberatory furnace with coke, silica, or soda ash to yield lead for refining, a copper–lead sulfide matte (and possibly speiss) for copper recovery, and slag for return to smelting. WebCupric sulfate, CuSO 4, commonly known as blue vitriol, is the most important salt of copper. It usually crystallizes as CuSO 4 · 5H 2 O and has a bright blue colour. It is prepared by the treatment of copper oxides with sulfuric acid. While readily soluble in water, it is insoluble in alcohol.
