Lead and Zinc - Energy

6.1.1 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.

Oct 27, 2015  While it has a high economic value, lead is relatively economical to produce. As with all metals, there are two main production routes. Primary production from mined lead ore is of course the original source of all lead, but secondary production, where it is recovered from recycled products or from residues arising from the production process is of enormous importance.

Sedimentary exhalative deposits - Wikipedia

Sedimentary exhalative deposits (SedEx or SEDEX deposits) are zinc-lead deposits originally interpreted to have been formed by discharge of metal-bearing basinal fluids onto the seaflor resulting in the precipitation of mainly stratiform ore, often with thin laminations of sulphide minerals. SEDEX deposits are hosted largely by clastic rocks deposited in intracontinental rifts or failed rift ...

Lead Statistics and Information - USGS.gov

Lead is a very corrosion-resistant, dense, ductile, and malleable blue-gray metal that has been used for at least 5,000 years. Early uses of lead included building materials, pigments for glazing ceramics, and pipes for transporting water. The castles and cathedrals of Europe contain considerable quantities of lead in decorative fixtures, roofs, pipes, and windows.
