| Abstract: |
| The sulfur slag from tin smelting system was treated with a new process composed of one stage leaching, oxidizing roasting, and second stage leaching. The treatment separates copper from tin smelting system, and produces high quality by-products of stannous sulfate and copper sulfate. This process is simple and environmentally friendly, low reagent consumption. |
