Sphalerite mineral

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.

Zinc is an important base metal required for various industrial applications [].It is mainly recovered from primary sulfide concentrates, sphalerite (ZnS) being the primary ore [2,3].The sphalerite composition varies depending on the sulfide mineral source and is commonly associated with other sulfides such as chalcopyrite, galena and pyrite [4,5].The metalliferous deposits: Gold, platinum, chromite, chalcopyrite, sphalerite, galena, bauxite, hematite, and magnetite. ...

Sphalerite: Galena and sphalerite commonly occur together and darker varieties of sphalerite may initially be confused with galena. Pure sphalerite samples can be distinguished from galena because they are harder (3.5 to 4) and have a lower specific gravity (3.9-4.1). The color of their streak provides an even simpler way to distinguish the two.
