| Abstract: |
| The slag volume is very large in zinc hydrometallurgy plant, and contains harmful substances such as H2SO4, Cu, Cd, Pb, Zn, In, As, Sb, F, Cl et al. long-term storage will cause environmental pollution and waste of resources. So the slag harmless treatment and recycling method should be researched greatly. This paper summarizes various methods of removing iron and the latest developments at home and abroad, which provides reference to the new plants of zinc hydrometallurgy in the respect of iron removal technology selection. The goethite method, hematite method, deep processing of iron in slag should be developed and applied, which are most likely to reach the harmless treatment. |
