Lead is extracted from ores dug from under-ground mines. Of the more than 60 minerals that contain lead, only 3 galena, cerussite and anglesite are commercially viable. Usually, lead is found in conjunction with other metals such as silver and zinc. Lead materials are mined as a
Lead ore is most commonly found as lead sulphide (PbS), galena, a heavy, shiny grey metallic ore with a conspicuous cubic cleavage, but locally pyromorphite, lead chlorophosphate (Pb 5 (PO 4) 3 Cl), was worked on Green Hill, near Charterhouse and on Blagdon Hill. Around Charterhouse, the lead ore contained small amounts of silver.
Ore deposits. Lead deposits are processed in three different classes, according to the fact that they are mined: only lead, lead and zinc, lead and silver. In recent years, lead silver ores have been the largest source of metal. Of great importance among others is the south-eastern region of Missouri. Galena is found both in layers and in veins.
Galena is the main ore of lead, used since ancient times.Because of its somewhat low melting point, it was easy to liberate by smelting.It typically forms in low-temperature sedimentary deposits. In some deposits the galena contains about 1–2% silver, a byproduct that far outweighs the main lead ore in revenue.In these deposits significant amounts of silver occur as included silver sulfide

Lead is easily extracted from its ores; prehistoric people in Western Asia knew of it. Galena is a principal ore of lead which often bears silver. Interest in silver helped initiate widespread extraction and use of lead in ancient Rome. Lead production declined after the fall of Rome and did not reach comparable levels until the Industrial Revolution. In 2014, the annual global production of lead was about ten million

Lead ore has a rather complex structure. It is processed for a long time and after melting of polymetallic ores lead is obtained. Judging by archaeological research, this metal has been known since ancient times. The oldest discovery was found in a burial with an age of 6000 years. The artifact form is a rod, its handle was wooden, but it had a lead tip.

Most lead mining prior to 1869 was from scattered and shallow workings above the water table. Workings were generally small and closely packed to recover the maximum amount of ore. In 1864 the St. Joseph Lead Company purchased lands in the vicinity of the town of Bonne Terre, which contained rich deposits of galena at or near the surface.
