Lead is chiefly obtained from the mineral galena by a roasting process. At least 40% of lead in the UK is recycled from secondary sources such as scrap batteries and pipes.

Lead is in column IVA of the periodic table. It has four naturally occurring stable isotopes, lead-204, lead-206, lead-207, and lead-208. The last three of these are all end products of one or another radioactive family. Lead is one of the first elements known to human societies.
Lead (pronounced "led") is a chemical element; it has symbol Pb (from Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue.
Both are formed by the weathering of galena. Over half of the lead produced in the world comes from just four regions and nations: the United States, Russia, other members of the former Soviet Union, Australia, and Canada.
Most lead is obtained by roasting galena in hot air, although nearly one third of the lead used in the United States is obtained through recycling efforts. Jefferson Lab, U.S. Department of Energy Long known, mentioned in Exodus.
Origin of its Name: It is named after the Anglo-Saxon word ‘lead’ while its symbol Pb is derived from the Latin word ‘plumbum’, meaning waterworks [1]. Who Discovered it: Since lead has been mined from the ancient times, its original discoverer is not known. When and Where was the Element Discovered
Most lead is obtained by roasting galena in hot air, although nearly one third of the lead used in the United States is obtained through recycling efforts. Lead is a soft, malleable and corrosion resistant material.
