Technology for producing cathode copper through high-pressure oxygen leaching of copper and nickel contained melting slag

The present invention discloses a process for copper smelting slag Nickel wetted HBO Treatment copper cathode, characterized in that the process steps performed by the order: (1) crushing and grinding; (2) high-pressure oxygen enriched leaching; ( 3) electrowinning copper; (4) removal of copper in addition to Ni, Sb, Bi acid separated: the present invention in place of the blast furnace and refining furnace with repetitive hydrometallurgical leaching solution after selective leaching can be electrically directly electrowinning copper cathode electrolyte and acid cycle off the product after use, can achieve continuous automatic control, good working conditions, low pollution and is conducive to environmental management, high recoveries. Pressurized oxygen-rich leaching process of copper slag refining process is short, adaptable to the raw material, valuable metals leaching rate, less impurity removal load solution, less material consumption, the production process does not produce emissions, waste and waste , it is pollution-free cleaning process. Corrosion resistance of the equipment requiring a lower energy, the recovery of copper, nickel, 98.5% copper reduced fees 6,000 yuan / ton of copper or less.
