| Abstract: |
| Leaching of rhenium-bearing tailings in copper production was studied. Effects of temperature, end point pH value, oxidant dosage, L/S, and leaching time on leaching rate of rhenium, copper and arsenic were investigated. The results show that leaching rate of rhenium, copper and arsenic is 81.72%, 0.15% and 94.19% respectively under the optimum leaching conditions including end point pH value of 1.0, oxidant dosage of 50%, time of 5 h, temperature of 80 ℃, and L/S=4/1. |
