Chromium drainage sand with chromite sand 20-70 mesh chromite sand South Africa 46% content chromite sand
Chromium ore sand is a special sand for foundry. It is a natural spinel mainly composed of chromite. Chromium ore is mainly used for surface sand of large steel castings in foundry production to prevent sand sticking on the surface of castings; secondly, it is used as refractory aggregate for casting coatings; It can replace part of the cold iron when used.

Uses of chrome ore
- Chromite sand is suitable for drainage sand raw materials, casting, ceramics, glass and refractory materials.
- Applicable types of chromite sand: foundry grade, metallurgical grade.
- Chromite sand is mainly used for surface sand of large steel castings in foundry production to prevent sand sticking on the surface of castings;
- Use its grinding powder as refractory aggregate for casting coatings. Chromium ore is a chilling material, which can replace part of the chilling iron in molding (core making).
- Chromite sand is suitable for casting coatings, refractory materials, automobile brake pads, high-performance ceramic materials
Ceramic and glass colorants, friction materials, chemical industry and metallurgical casting and other fields.
