Lead Ore

Name and Composition - Lead: Galena (Lead glance): PBS, Anglesite; PbSO4.

Physical Properties - Lead ore (Galena): It occurs as lead grey coloured mineral. The grains are generally cubic having metallic luster on fresh surfaces. Streak is lead grey colored, hardness is 2 to 3 and is 7.4 to 7.6.

Mode of Occurrence - Syn–sedimentary deposits. Mineralization genially occurs as en-echelon shoots/lodes in dolomite, quartz-chlorite-biotite schist, augen gneisses etc.

Uses - Cadmium is used in the manufacture of Ni-Cd storage batteries Coating and electroplating, pigment industries, in plastics and synthetic product, for manufacturing of alloys (cadmium base alloys are used in high strength, high conductivity and high resistance to abrasion, therefor it is used in electric transmission wires.

Mineral based Industries – Lead smelter, recycling units.

Industrial Prospects – Handicrafts, storage battery, dry battery, zinc foil, galvansing industries.
