  • Lead

    Clean metallic lead can be melted and refined directly, but compounds and lead alloys require smelting, using processes similar to those used with lead ores. Two-stage process In the two-stage process for secondary production, smaller rotary or reverberatory furnaces (Figure 3) are used rather than larger blast furnaces as this gives better control of the quality of the lead.
