South africa chromite sand is a product of south africa natural chromite ore after crushing and sieving, and its main chemical composition is Cr2O3.

The wide range in chromite compositions is explained by the influence of late-magmatic processes including post-cumulus growth and re-equilibration, interaction with fluid- and sulphide-saturated magmatic liquid and contact metamorphism.

Application for South Africa Foundry Chromite sand. Chromite Sand in the foundry industry. Its properties enable the material to be used in high duty grey iron and steel foundries as core and mould making sand. Its high thermal conductivity gives it good chilling properties, low thermal expansion gives rise to good dimensional stability.
