Extraction of Lead

Extraction of Lead 1 Introduction • Lead is a chemical element with atomic number 82 and symbol Pb It is a soft, malleable, and heavy metal Its melting point is 327 oC Freshly cut lead has a bluishwhite color that soon tarnishes to a dull grayish color Lead mining; Lead metal can be classified as either primary or secondary Primary lead is produced directly from mined lead ore whereas secondary lead is produced from scrap lead products (such as automobile batteries) which have been recycled Total annual production is approximately 8 million tonnes, half of which is primary lead It is rare to find pure deposits of lead in nature thoughLead: smelting, producing and classificationMetalpedia Metals which are at the centers of the lower parts of the electrochemical series like iron, zinc, tin, lead, cadmium are produced by carbon reduction of their oxides at high temperature whereby the metal is obtained in the molten state The process is often referred to as smeltingExtraction of Metals (Metallurgy) – Overall Science
