Lead Ore / Lead Concentrate Smelting, Manufacturing Technique

In mining, the ore is extracted by drilling or blasting and then crushed and ground. The ore is then treated using extractive metallurgy. The Froth flotation process separates the Lead and other minerals from the waste rock (tailings) to form a concentrate. The concentrate, which can range from 50% to 60% Lead, is dried and then treated using

Lead Ore

The oxide lead ore in a dolomitic matrix may contain clay slimes and a fairly large amount of pyrite and barite; both of these minerals have a negative effect on oxide lead flotation. These ores may contain one or several lead minerals, including cerussite, anglesite and pyromorphite. Some lead oxide ore varieties may contain oxide copper minerals in the range of 0.2–1% Cu.

Extraction of Lead

Flotation • The principal lead ore, galena, is properly known as lead sulfide, and sulfur makes up a substantial portion of the mineral. The flotation process collects the sulfur-bearing portions of the ore, which also contains the valuable metal. • First, the finely crushed ore is diluted with water and then poured into a tank called a flotation cell. The ground ore and water mixture is
