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.

Description Chromite is a mineral that contains chromium, iron, and oxygen, with varying amounts of magnesium and aluminum, and has a high specific density. Its chemical formula is (Fe,Mg)O*(Cr,Fe,Al)2O3. Particularly chrome ores, out of which foundry grade chromite sand can be made, are only found in the Bushveld Complex in South Africa. Chromite sand is

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. It is used as a highly fireproof sharpener for moulds and cores. Originally from South Africa. The sand is produced by
