Extraction of Lead - SlideShare

20-02-2017· 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 bluish-white color that soon tarnishes to a dull grayish color when exposed to air; as a liquid, it has a shiny chrome-silver luster.Lead - Essential Chemical Industry,Lead is extracted from its ore by reduction with carbon.
