Chromite sand is used as a highly fireproof sharpener for moulds and cores. Originally from South Africa . The sand is produced by crushing chrome ore and its washing in spiral concentrators, subsequent drying, dust cleaning, screening and sorting as per grain size.

Chromite sand, also known as chrome ore sand or cr-sand, is a special sand for foundry. It is a natural spinel mainly made of chromite. It is crushed, ground, and sieved into a specified particle size, suitable for modeling (core making) sand

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. physical and chemical properties: Melting point of 2150°C Good thermal conductivity Good resistance to thermal shock Excellent resistance to metal penetration
