Description

кадми  3. Порцию кека загружают в мешалку и репульпируют водой до ж: т 3:1, ввод т серную кислоту до содержани  ее в растворе 6 г/л. После этого небольшими дозами ,в пульпу добавл ют нитрит натри  в количестве 5% к исходной загрузке кека (1 часть на 6 частей цинка). Выщелачивание ведут при 40°С 1,6 ч. Затем пульпу отфильтровывают. Промытый твердый остаток содержит, %: 8,3 кобальта; 0,35 цинка, 1,2 кадми .cadmium 3. A portion of the cake is loaded into the mixer and repulped with water until the liquid 3: 1 is added, sulfuric acid is added to keep it in a solution of 6 g / l. After that, in small doses, sodium nitrite is added to the pulp in an amount of 5% to the initial loading of the cake (1 part to 6 parts of zinc). Leaching is carried out at 40 ° C for 1.6 hours. Then the pulp is filtered off. The washed solid residue contains,%: 8.3 cobalt; 0.35 zinc, 1.2 cadmium.

Раствор содержит: 80 г/л цинка, 320 мг/л кадми , кобальт не обнаружен, т. е. этот раствор вполне пригоден дл  переработки в основной технологической схеме.The solution contains: 80 g / l of zinc, 320 mg / l of cadmium, no cobalt is detected, i.e. this solution is quite suitable for processing in the main technological scheme.
