Chromium ore sand, also known as chromite ore, 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 moulding (core-making). Chromium ore sand can be divided into two grades according to chemical composition, first grade Cr2O3 (> 45%) and second grade Cr2O3 (> 35%). Chromium ore sand is mainly used in surface sand of large steel castings in casting production to prevent sand sticking on the surface of castings; secondly, its grinding powder is used in refractory aggregate of casting coatings; chromium ore sand is chilling material, which can replace part of chilled iron in moulding (core making).
