| 成果简介 | NOVELTY - Invention relates to hydrometallurgy of non-ferrous metals, namely to methods for selective deposition of copper from solutions of autoclave and atmospheric leaching of white matte, matte, and can be used in the development of hydrometallurgical technology of copper-nickel solutions containing, along with nickel and copper, platinum group metals. Method involves adding nickel sulphide to a copper-nickel solution at temperature of 50-90 °C and pH of solution is 3-7 to form nickel sulphate and insoluble copper sulphide. Precipitation is carried out with wet freshly deposited nickel sulphide from copper-nickel solutions containing up to 40 g/dm3 copper and up to 110 g/dm 3 nickel, wherein nickel sulphide is obtained from solution of autoclave or atmospheric leaching of white matte or matte after purification from copper by precipitation with sodium hydrosulphide. USE - Metallurgy. ADVANTAGE - Method makes it possible to increase degree of copper deposition, to minimize contamination of solutions sent for nickel electrodeposition with impurities. 1 cl, 1 dwg, 5 ex |
