| 摘要 |
The invention relates to a method for producing metallic lead from lead-containing starting materials by an oxidizing smelting process and subsequent reduction of the resultant oxidic molten bath. The reduction is effected with solid carbonaceous reduction agent present in the melt, and it is ensured that solid carbonate-containing material, preferably limestone, dolomite or soda ash, is also present in the melt, together with the reduction agent. The method can be applied for working-up lead-starting materials of sulphidic, oxidic or sulphatic kind. In addition, the method can be applied to advantage for working-up lead-carbonate containing starting materials, where at least a part of the carbonate-containing material may comprise lead-starting material. |
