| Abstract: |
| Effects of sodium chlorate dosage, sulfuric acid concentration, temperature, and leaching duration on extraction of copper, rhenium, arsenic, and lead from rhenium slag were investigated by single factor experiment. The results show that leaching rate of copper, rhenium, arsenic, and lead is 98.75%, 98.32%, 99.16%, and 5.91% respectively under the optimum conditions including sodium chlorate dosage of 0.4 times of slag, sulfuric acid concentration of 1.5 mol/L, L/S=5, leaching temperature of 80 ℃, and leaching duration of 1 h. |
