Sphalerite rock.
Sphalerite has been mined from the Hutson Mine in Livingston County, and the Lexington Quarry Co . has mined sphalerite from a vein deposit in Jessamine County for several years, producing very fine, dark brown to black, tetrahedral crystals. There is a large unmined zinc deposit in southern Kentucky (Anderson and Price, 1991). The

Sphalerite is a zinc ore containing iron When its iron is high, its color becomes matte black Materials that have the quality of jewels have less iron content and as a result their crystals are transparent. Due to its low hardness, it is considered a gem for collectors Sphalerite is a sulfide mineral with the chemical formula S. It is the most important ore of zinc. Sphalerite is found in a variety of deposit types, but it is primarily in sedimentary exhalative, Mississippi-Valley type, and volcanogenic massive sulfide deposits. It is found in association with galena, chalcopyrite, pyrite , calcite, dolomite, quartz, rhodochrosite, and fluorite.
Sphalerite dissolution kinetics were studied by means of long-term (>500 h) flow-through experiments in the pH range of 1–4.2, at 25, 50 and 70 °C and at three different dissolved O 2 concentrations, from 0.2 to 8.7 mg L −1 to obtain a dissolution rate law useful to predict sphalerite long-term dissolution behavior in environments affected by acid drainage.
The sphalerite chemical formula is ZnS (zinc sulfide.) This chemical formula represents sphalerite in its pure form, but it is much more commonly found with significant amount of other elements substituting zinc. Up to 26 % Fe, 17 % Cd, 15 % Hg, 21 % Mn and small amounts of Cu, In, Ga, Ge and As may replace the zinc.Category: Science & Tech also called: blende, or zinc blende sulfide mineral ore wurtzite See all related content → sphalerite, also called blende, or zinc blende, zinc sulfide (ZnS), the chief ore mineral of zinc.

Sphalerite IIa, hosted in biotite schist, occurs as coarser, irregular-shaped areas (Fig. 5a), thus being distinct from type Ia. This type is typified by inclusions of pyrrhotite and lesser chalcopyrite (Fig. 5b). In this case, cassiterite is present as coarser (100–200 μm ...Zinc sulfide (ZnS) is a unique compound that forms two types of crystalline structures. These two polymorphs are wurtzite and zincblende (also known as sphalerite). Wurtzite has a hexagonal structure, while zincblende is cubic. It is characterized by single bonds between each atom and maintenance of a 1:1 zinc to sulfur ratio.
