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.the chromite powder for colorant can decrease cost to make green or tea color for glass products, and less pollution to instead chemical colorant.
