Abstract

1. Способ переработки медеэлектролитного шлама, включающий обезмеживание, выщелачивание селена из обезмеженного шлама и (или) продуктов его обогащения в щелочном электролите, отличающийся тем, что выщелачивание селена проводят в водной системе, содержащей восстановитель, а в качестве восстановителя используют электроотрицательные металлы, водорастворимые органические или неорганические соединения, обеспечивающие нормальный окислительно-восстановительный потенциал системы в щелочной среде положительное - 0,3 В по отношению к водородному электроду.2. Способ по п.2, отличающийся тем, что выщелачивание селена проводят в растворе, содержащем 50-200 г/л сахара, 20-100 г/л щелочи при температуре 70-90°C.1. A method of processing copper electrolyte sludge, including de-curing, leaching of selenium from de-coarse sludge and (or) its enrichment products in an alkaline electrolyte, characterized in that the leaching of selenium is carried out in an aqueous system containing a reducing agent, and electronegative metals, water-soluble organic or inorganic compounds that provide the normal redox potential of the system in an alkaline medium, positive - 0.3 V with respect to the hydrogen electrode. 2. The method according to claim 2, characterized in that the leaching of selenium is carried out in a solution containing 50-200 g / l of sugar, 20-100 g / l of alkali at a temperature of 70-90 ° C.
