| Abstract: |
| The result of lead direct smelting by oxygen side-blowing in pilot-plant-scale indicates that lead concentrate and residue and dust can be smelted in Oxygen Side-blowing Furnace to produce crude lead, which coal is used as reducing agent. The recovery ratio of lead is more than 96%. SO_2 concentrate in waste gas is more than 24%.The off-gas can be treated by producing sulphuric acid directly. This process has many advantages, such as less investment, high efficiency, short process flow, simple equipment and low pollution. As a result, it can be used for producing lead widely. |
