Изобретение относится к химической технологии и цветной металлургии и может быть использовано при выделении сернокислых солей из кислых сред, катодных осадков меди из оборотных промывных вод и маточника при переработке шахтных вод. Способ корректировки исходных растворов для электролиза меди включает выделение меди путем добавления в раствор серной кислоты, кристаллизацию меди и отделение промывных вод и маточника от медного купороса, при этом после кристаллизации из промывных вод и маточника при поддержке соотношения меди и серной кислоты в интервале (13 - 25) : (500 - 600) и (7 - 10) : (30 - 40) г/л соответственно ведут электролиз меди при плотности тока 150 - 300 А/м. В качестве исходных растворов для электролиза меди используют шахтные воды.The invention relates to chemical technology and non-ferrous metallurgy and can be used in the separation of sulfate salts from acidic environments, cathode deposits of copper from reverse wash water and mother liquor in the processing of mine water. The method for adjusting the initial solutions for copper electrolysis involves the selection of copper by adding sulfuric acid to the solution, crystallization of copper, and separation of the washings and mother liquor from copper sulfate, while after crystallization from washings and mother liquors, the ratio of copper and sulfuric acid is maintained in the range (13 - 25): (500 - 600) and (7 - 10): (30 - 40) g / l respectively conduct electrolysis of copper at a current density of 150 - 300 A / m. Mineral waters are used as initial solutions for copper electrolysis.
