| Abstract: | The technological process of recovering copper and zinc from waste CuO-ZnO catalyst by dissolution with sulphuric acid and replacement with zinc powder was studied in detail. The purity of the copper obtained was more than 97% and ZnSO4-7H2O 89.17%. The efficiency of recovery of copper and zinc Came to 96.4% and 92.8% respectively. Closed circle was used in the technological process and no pollution of the waste water, gas and residue |
