| Abstract: | The best technical condition with hydrometallurgical separation and reclamation from smelting lead waste residue by the orthogonal experiment was studied. It was showed that the reclamation ratios of lead and copper were 85.52% and 89.65% respectively when the nitric acid concentration was 6 mol/L,soaking temperature was 60 ℃,the time was 50 min,the ratio between liquid and solid was 4∶1. The process flow possessed two advantages：operating simply and avoiding reproducing pollution,so it could bring the better economic,environmental and social benefits. |
