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.

Placer mining is used when the metal of interest is associated with sediment in a stream bed or floodplain. Bulldozers, dredges, or hydraulic jets of water (a process called ''hydraulic mining'') are used to extract the ore. Placer mining is usually aimed at removing gold from stream sediments and floodplains.

Because lead can be absorbed through dermal and mouth contact, this form of exposure can be particularly dangerous for children. Miners are also at risk of exposure if they do not have protective equipment and frequently come into direct contact with ore containing lead. Miners can also inhale lead as dust during the mining and crushing processes.

Once the lead ore is mined, it must undergo several different processes in order to be turned into usable or metallurgical lead material: sintering, smelting, and refining. The sintering phase involves removing sulfur from the lead ore using a hot air combustion process.

The majority of the deposits are mixtures of minerals, hence lead ore is usually obtained as a byproduct of other metal mining such as zinc, silver or copper. In fact, lead ore is a main source of silver and contributes substantially towards the world''s total output. The most common lead ore is galena (PbS), which contains % lead.

Process Overview Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist. learn more
