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 Foundry grade has been the preferred raw material for the elaboration of resin bonded casting cores and moulds in the steel foundries for many years.
