Description

Степень извлечени  серебра составл ет 98-99%. The silver recovery rate is 98-99%.

Пример. В 100 мл 4NH2SO4.помещают 10 г положительных и отрицательных электродов следующего состава: Ag 51,3%; Си Zn 20,1%. Обработку кислотой провод т в течение 2 ч. После этого раствор отфильтровывают и выпаривают, в результате получают 8,8 г цинкового купороса . Осадок обрабатывают в 100 мл 4NH2SO4 с добавлением 5% перекиси водорода (по объему) в течение 2 ч при 40°С. Отфильтрованный раствор выпаривают и получают 10,9 г медного купороса. Осадок высущивают, отсеивают электрохимический серебр ный порощок, вес которого составл ет 3,7 г (с содержанием серебра 98%), аExample. In 100 ml of 4NH2SO4. 10 g of positive and negative electrodes of the following composition are placed: Ag 51.3%; C Zn 20.1%. The acid treatment is carried out for 2 hours. After that, the solution is filtered and evaporated, resulting in 8.8 g of zinc sulfate. The precipitate is treated in 100 ml of 4NH2SO4 with the addition of 5% hydrogen peroxide (by volume) for 2 hours at 40 ° C. The filtered solution is evaporated and 10.9 g of copper sulphate are obtained. The precipitate was dried, screened with an electrochemical silver powder, the weight of which was 3.7 g (with a silver content of 98%), and

скрап весом 1,5 г с содержанием серебра 96,7% направл ют на плавку.Scrap weighing 1.5 g with a silver content of 96.7% is sent to smelting.
