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 is a special sand for foundry. It is a natural spinel dominated by chromite. After crushing, grinding and sieving, it is divided into prescribed grain size, and is suitable for sand for molding (core-making). Chromium ore sand can be divided into two grades according to chemical composition, first grade Cr2O3 (> 45%) and second grade Cr2O3 (> 35%).
