| Abstract: |
| With zinc leaching residue as raw materials, leaching test of zinc leaching residue with sulfuric acid was carried out to investigate influence factors on leaching of zinc and germanium. The results show that leaching rate of Zn and Ge is 93% above and 90% above respectively under the conditions including grinding fineness of -0.074 mm of 78.68%, ammonium fluoride dosage of 50 mL (concentration of 5%), sulfuric acid dosage of 120 mL (concentration of 30%), L/S of 4︰1, leaching temperature of 85 ℃, and leaching time of 3 h. |
