6.1.2.3 Lead Ore Processing Lead ore beneficiating includes milling, concentration, and sintering. After sintering, the ore is smelted in a blast furnace to produce rough lead bullion. Rough lead bullion still contains many impurities. Therefore, the rough lead bullion is refined to remove and recover other metals.


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.

Primary Metals. Table of Contents Industry Overview Steel Making Industry Ferrous & Non-Ferrous Foundries Aluminum Smelting & Refining Copper Processing Lead Processing Zinc Processing Glossary. 6 Lead Processing. The US is the third largest producer of primary lead, with most coming from Missouri. The primary end users of lead are batteries and ammunition.


Lead is extracted from ores dug from under-ground mines. Lead is also 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 tedious process. First the lead ore is ground into small salt-like particles.


After crushing into small pieces, the heavy Lead ore was sorted from the waste in a variety of processes using water. Various stages of processing were used involving equipment called jiggers, buddles and dolly tubs. All these used the tendency of the heavy Lead ore to settle more quickly in water than the lighter waste.
