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 - Lead metal has several useful mechanical properties, including high density, low melting point, ductility and relative inertness. The largest use of lead in the early 21st century is in lead–acid batteries. Lead's high density, atomic number and formability form the basis for use of lead as a barrier that absorbs sound, vibration, radiation, pipe industries, storage batteries and nuclear containers. Lead has also uses in the construction industry; lead sheets are used as architectural metals in roofing material, cladding, flashing, gutters and gutter joints and on roof parapets.

Mineral based Industries – Lead smelter, recycling units.

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