JH17981 Calcite, Skorpion Mine, Namibia

Description

Up for bid is a specimen of white fluorescing Calcite from the Skorpion Mine in Namibia. Calcite for this location is rare.
The Skorpion Mine is the 8th largest Zinc mine in the world and is unique in several ways. It is one of the few Zinc deposits that is composed almost exclusively of Zinc Silicates like Sauconite (Formula: Na0.3Zn3(SiAl)4O10(OH)2·4H2O) and Hemimorphite (Formula: Zn4(Si2O7)(OH)2·H2O) and Zinc Carbonates like Smithsonite (Formula: ZnCO3) and Hydrozincite (Formula: Zn5(CO3)2(OH)6). Most other Zinc deposits contain Zinc Sulfides like Sphalerite (Formula: (Zn, Fe)S).
The Skoprion mine is also the only zinc processing facility to use solvent extraction-electrowinning metallurgy to process and refine its zinc products (others use conventional smelting and roasting). The combination of Zinc Silicate and Zinc Carbonate ores and the extraction-electrowinning process allow Skorpion to sell a Special High Grade (SHG), ultra-pure zinc product, which is so low in impurities that it commands a premium price.
