FIELD: metallurgy.
SUBSTANCE: procedure consists in production of copper powder in form of cathode sediment, nickel solution and non-soluble slag concentrating sulphur and precious metals. For this purpose alloy is subjected to electro-chemical anode dissolving in water solution. Also, sulphide copper-nickel alloy in form of granules of size 0.5-5.0 mm used as bulk anode is subjected to anode dissolving. Electrolysis is performed at anode density of current 20.0-40.0 A/m2. As source alloy there is used nickel, copper-nickel matte or white matte. Sulphuric acid is used as non-organic acid.
EFFECT: increased completeness of alloy dissolving and transition of sulphur into elementary state.
