12.6 Primary Lead Smelting

12.6 Primary Lead Smelting 12.6.1 General15 Lead is found naturally as a sulfide ore containing small amounts of copper, iron, zinc, precious metals, and other trace elements. The lead in this ore, typically after being concentrated at or near the mine (see Section 12.18), is processed into metallurgical lead at 4 facilities in the U. S.

Lead (Pb) Ore | Properties, Minerals, Formation, Deposits

Lead ore is primarily composed of lead sulfide (PbS), which is the most common mineral form of lead. Other minerals that may be present in lead ore deposits include cerussite (lead carbonate, PbCO3), anglesite (lead sulfate, PbSO4), galenite (lead sulfide, PbS), and other lead-bearing minerals. The concentration of lead in lead ore deposits can vary widely, ranging …

Lead Refining

Over 90% of the zinc is recovered, leaving approximately 0.05% in the lead bullion. To remove the last traces of zinc, the lead is treated with molten caustic soda reducing the final level to <1 ppm. The next stage of primary lead refining is the removal of bismuth.

Metallurgy

Many types of furnace are used for reduction smelting. The blast furnace is universally used in the reduction of such compounds as iron oxide, zinc oxide, and lead oxide, though there are great differences between the furnace designs used in each case. Iron, found naturally in the oxide ores hematite and magnetite, is smelted in a tall, circular, sealed blast furnace (see figure).
