The Everyday Use Of Sphalerite

Sphalerite is a type of mineral ore that can be cut as a gemstone. Although it is sometimes used in jewelry or as a display piece, it has a variety of other important uses.


Composition








Sphalerite is an ore of zinc with smaller amounts of other elements, usually sulfur and iron. Sphalerite may also contain gold, silver, and cadmium.


Jewelry


Sphalerite has a high index of refraction, which gives it a striking luster. It can be found in a variety of colors, ranging from colorless to green, red, or even black. These attributes can make it an attractive choice for jewelry.


Display Pieces


Sphalerite is a fairly soft gemstone, so it is sometimes considered too soft for regular use in jewelry. It is often displayed as an attractive cabinet mineral specimen.


Industrial Uses


Sphalerite is the most important source of industrial zinc, which is used in processes ranging from galvanizing iron to making batteries. In addition, sphalerite is an important source of some rarer minerals, such as cadmium.


Other Uses


Zinc sulfate, which is made from sphalerite, is used as a mineral supplement in animal feed, as well as an astringent in medicine, and a preservative for leather goods.
