Introduction: sphalerite is one of the commonest sulphides, occurring in a wide range of hydrothermal mineral deposits formed in various geological settings. It is best-known, however, from two types of ore deposits - firstly Mississippi Valley-type (MVT) vein associations and secondly stratiform carbonate hosted synsedimentary massive sulphide …

Sphalerite is a zinc ore, and its name pertains to the Greek word that means 'treacherous'. This is because it looks a lot like Galena, only it does not contain lead, much to the disappointment of early miners. Sphalerite is a significant zinc ore which is usually found in hydrothermal veins.

Sphalerite, zinc sulfide, is and has been the principal ore mineral in the world. Zinc uses range from metal products to rubber and medicines. Zinc alloys readily with other metals and is chemically active. On exposure to air, it develops a thin gray oxide film (patina), which inhibits deeper oxidation (corrosion) of the metal. The metal's ...

Black Sphalerite is a unique variety of Sphalerite that is characterized by its deep black color, which is caused by the presence of iron content impurities in the mineral. Black Sphalerite is highly valued for its distinctive appearance, and is often sought after by collectors and spiritual practitioners alike.

The sphalerite mineral, or "zinc blende," is most widely known as an important source of zinc. In fact, roughly 95 percent of the world's zinc comes from sphalerite! As a semi-precious gemstone, …

PolishedRoughJewelry. Sphalerite makes an excellent collector's stone, but it is too soft for jewelry. It is difficult to cut and polish due to perfect cleavage in six directions. Gemstone-quality material, when faceted, is remarkable due to its incredibly high dispersion.

Sphalerite is a polymorph with two minerals, wurtzite and matraite . The three are called polymorphs (meaning many shapes) because although they have the same chemistry, (Zn, Fe)S or zinc iron sulfide, they have different structures and therefore different shapes. Sphalerite is by far the more common mineral of the three.
