| Abstract: |
| Rhenium rich slag was leached with hydrogen peroxide under atmospheric pressure. Effects of L/S, dosage of hydrogen peroxide, concentration of sulfuric acid, leaching temperature and leaching time on rhenium leaching rate were investigated. The results show that average leaching rate of rhenium is 96.52% under the optimum conditions including L/S=2/1, volume of hydrogen peroxide of twice of water, concentration of sulfuric acid of 20 g/L, and leaching time of 2 h at room temperature. |
