摘要

method of processing copper u043au0430u0434u043cu0438u0435u0432u043eu0433u043e w. m. keck, comprising leaching the spent zinc electrolyte u0446u0435u043cu0435u043du0442u0430u0446u0438u044e cadmium with zinc dust in the presence of 80 90C wii ions of copper and antimony in obtaining create lips lips, dissolving in water solution of sulphuric acid to obtain the rich cadmium solution and cleaning u0440u0430u0441u0442u0432u043e ra and with the fact that, in order to simplify technologythe leaching of lead to the residual acidity 15 to 20 g / l, the ratio of copper to carry out u0434u043eu043eu0441u0430u0436u0434u0435u043du0438u0435 copper, cobalt 10 - 15: 1 and ph between 3.5 and 4.0, and deposition of lead in create lips one stage in the u0440u0430u0441u0445u043eu0434u0435 zinc dust 1.1 to 1.2 kg per 1 kg of cadmium in solution.
