| Abstract: |
| Based on the characteristic of refractory tellurium-bearing waste residue after extracting noble metals in certain factory, the tellurium leaching rate of general basic leaching process is only less than 10%, the tellurium leaching rate is less than 79% using hydrogen peroxide oxidation leaching in sulfuric acid and sodium chloride solution. But it can improved evidently by using a new craft of potassium permanganate oxidation leaching in sulfuric acid solution at normal temperature. The experiment results show that the tellurium leaching rate can reach 92% after leaching 5 hours. |
