Lead Ore / Lead Concentrate Smelting, Manufacturing

The primary ore is galena or Lead sulphite PbS. This is unstable, and on prolonged exposure to the atmosphere it oxidizes into the minerals cerussite PbCO3 and anglesite PbSO4. Lead ores are usually associated with other metals, particularly silver which can be mined at the same time and zinc, which can cause problems during smelting.get price

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. (2 smelters/refineries in Missouri, 1 smelter in Montana, and 1 refinery in Nebraska).get price

Environmental Impacts of Lead Ore Mining and Smelting Health

In this paper, the impact of mining and smelting of lead metal ores on environmental quality is described. Globally mines produce large amounts of waste because the ore is only a small fraction of the total volume of the mined material.

Smelting

Smelting is a process of applying heat to ore in order to extract a base metal. [1] It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slagget price
