James Smithson. The carbonate "calamine" was re-named smithsonite in 1832 by François Sulpice Beudant in honor of James Smithson [1754-1829], British chemist, mineralogist, and benefactor of the Smithsonian Institution (Washington, DC, USA). Siderite-Smithsonite Series. Smithsonite is often found as a secondary mineral in the oxidation zone of zinc ore deposits.
Heap leaching Wikipedia. Heap leaching is an industrial mining process to extract precious metals, copper, uranium, and other compounds from ore via a series of chemical reactions that absorb specific minerals and then reseparates them after their division from other earth materials.

Zinc mining - Wikipedia. A zinc mine is a mine that produces zinc metal. Some mines produce primarily zinc, but some mines produce zinc as a side-product of some metal that has a higher concentration in the ore. Most zinc mines produce zinc and lead or zinc and nickel. The world's biggest zinc mine is Rampura Agucha Mine in Rajasthan,...

Crystallinity implies that a mineral has a definite and limited range of composition, and that the composition is expressible as a chemical formula. Some definitions of minerals give them as inorganic materials, however both diamonds and graphite are considered minerals, and both are primarily comprised of carbon, which would make them organic.
The Mining Process. The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
Mining Sapphire in Australia. A major source of sapphire is Queensland in Australia's northeast. In fact sapphire has been mined commercially for more than 100 years on the Anakie field in Central Queensland, which also yields gem-quality zircon and, more rarely, diamonds. Sapphire is found in a wide range of colors, including blue, green,...
Abstract The Southeast Missouri Barite District and the Valles Mines are located in Washington, Jefferson, and St. Francois Counties, Missouri, where barite and lead ore are present together in surficial and near-surface deposits. Lead mining in the area began in .
In calcite, smithsonite is such ore with high hardness and high proportion. Sphalerite is the majority ore that contains zinc in nature, smithsonite is much less relatively. Sphalerite is the most widespread of zinc mineral, mainly for hydrothermal genesis, almost always symbiosis with galena. it is easy weathering into smithsonite in surface.
At one time smithsonite was a major zinc ore mineral in the state. Eventually mining worked through these surficial deposits and zinc production shifted to the mostly unaltered sphalerite found at depth. Smithsonite, however, was encountered in blankets and veins reaching well below the present groundwater table (Heyl et al., 1959).
