| Abstract: | A method for simultaneous removal of the majon impurities i. e. As,Sb,Bi from the spent copper electrolyte based upon coprecipitation methods was researched. The used co-precipitant is hydrated manganese dioxide formed by potassium permanganate with manganous sulfate. The technical process was studied and its optimum technical conditions were found. Under these conditions, the purification rate of As,Sb,Bi is separately 93-27% ,97. 91% and 97. 82%. The result of purification can satisfy the demand of industrial production. |
