Lead / ˈ l ɛ d / is a chemical element with the symbol Pb from the Latin plumbum and atomic number 82. It is a heavy metal that is denser thanmon materials. Lead is soft and malleable, and also has a relatively low melting point.When freshly cut, lead is silvery with a hint of blue it tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any
Lead acetate, known as lead sugar, is important in various industries. Due to its rich lead and zinc element, lead and zinc ore has an excellent ability to develop. It is widely used in the production of electrical engineering, in mechanical engineering, military industry, metallurgy, light,tical and chemical industries.

Primary Lead Processing Primary lead production begins with sintering. Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. The mixture is blasted with hot air to burn off the sulfur and sent to the smelter.
Lead poisoning can occur during ore extraction, lead smelting, and the manufacture of lead paints as well as in printing, cable manufacture, the manufacture of ceramics, and the preparation and use of tetraethyllead. Poisoning in the home, which is rare, results from the ingestion of food that has been stored for a long time in earthenware vessels coated with a glaze containing minium or
