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.

Mineral Processing. If the mineralogy of the ore shows that you can separate discrete particles of the mineral you want from the gangue components of the ore, then it is possible to physically concentrate the valuable mineral and reject the rest. The easiest method for achieving this is by gravity separation.

General : extracting silver from galena
There is an old method, called the Parkes process, which was used to separate silver (and gold) from lead. The argentiferous galena is first reduced to metallic lead, Then zinc is added to the molten lead, The silver is much more soluble in the zinc. The zinc rises to the surface, taking most of the silver with it.
