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.

ORE PROCESSING. The present lead mine concentrator was built in 1966 with rod and ball milling, lead-silver flotation, zinc flotation and low-grade middlings recovery circuits. In 1982, MIM added heavy-medium separation to pre-concentrate the mill feed. Later enhancements have included column cell flotation.

Usually, lead is found in conjunction with other metals such as silver and zinc. Lead materials are mined as a by product of these other more valuable metals. Extracting the lead materials from the ore is a multi-step process. First the lead ore is ground into small particles that are less than 0.1mm, giving the ore a texture similar to table salt.

allurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sin-tering, into a primary smelter. Lead concentra-tions can be 50–70%, and the sulfur content of sulfidic ores is in the range of 15–20%. Zinc con-centration is in the range of 40–60%, with sulfur content in sulfidic ores in the range of 26–34%.
