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.

Beneficiation of a Low Grade Lead Ore by Gravity Pre

This study is to investigate the beneficiating possibility of a low grade lead ore in Yunnan by current mineral processing technology. A low grade lead ore sample assaying 1.14%Pb and 5.72g/t Ag was used in tests. In the experiment, gravity preconcentration to discard the tailings and the effects of grinding fineness, types and dosages of reagents in roughing were investigated.
