| Abstract: |
| Lead was recovered from lead slag of antimony refining by nitric acid leaching process. The effects of ratio of liquid to solid (L/S), leaching temperature and time, and nitric acid concentration on lead leaching rate were investigated. The results show that the lead leaching rate is above 94% under the optimum conditions including L/S of 4, leaching temperature of 80 ℃, leaching time of 50 min, and nitric acid concentration of 7.0 mol/L. |
