Chromite sand is a naturally occurring spinel consisting primarily of the oxides of chrome and iron. It is a by-product of ferro-chrome production and is mainly used in foundry applications and in glass production.

Chromite sand is used for foundry (AFS 45-50), as a molding material in the manufacture of foundry molds and cores (both whole and their facing layer), as well as for the manufacture of heat-stressed sections of molds and cores; steel large-size thick-walled casting, production of the starting mixture. In the refractory industry – for the
