| Abstract: |
| In this paper, using " sulfuric acid oxidative leaching - pre - tannic acid precipitate germanium " enrichment of the element germanium from metal smelting slag which containing germanium, lead, zinc, copper, iron and other elements .This experiment investigated three methods of sulfuric acid oxidative leaching: oxygen pressure leaching, sodium persulfate oxidative leaching, hydrogen peroxide oxidative leaching, and obtained the best experimental conditions. In the experiment by using tannic acid precipitation of germanium , enables sediment in the germanium content is increased to above 10% . |
