Chromite ore is a naturally occurring mineral in the form of iron-chromium oxide FeCr2O4. South African chromite has all the above elements Mg-Al and Fe chromite MgFe (Al-Cr) 2O3. There are several types of Chromite sand such as metallurgical grade chromite, casting grade chromite, and chemical grade chromite after chrome ore get mined. One-third of the world’s chromite reserves are in South Africa. The LG layer of South African chromite has a high grade with a chromium content of 45-46%. This type of chromite sand is suitable for casting and refractory materials.

As refractory material in foundry feiled, chromite sand has multiple advantages such as high specific gravity, strong heat conductivity, fast cooling, high refractory temperature, small thermal expansion coefficient, and good slag resistance. Chromite sand AFS45-50  can work as casting sand in different casting processes.

Iron Chromite flour 200 mesh-2500 mesh fine powder has large range of usage in pigment, refractory,foundry and ware-resistant industrys.

Chromium filler sand is a refractory material for ladle made of chromite ore sand. It is better than silicon drainage sand and can increase the pouring rate of ladle. The chromite sand fineness for ladle filler sand is mainly 0.2-0.4mm,0.2-0.6mm, 0.2-0.8mm.

Chrome ore powder is one of the indispensable raw materials in industrial fields such as refractory materials, casting, glass manufacturing, and ceramic glazes. Chromium ore powder comes from natural chromite ore. Chromium ore with a chromium content of less than 40% can only be used in the metallurgical field for the smelting of ferrochrome metal. Only chromium ore with a chromium content of more than 40% is meaningful for deep processing. Raw materials with a chromium content of 40-42% in South Africa, 46-47% in Zimbabwe, and 48-50% in Zimbabwe are selected. The production process including ore selection, washing, drying, screening, and fine milling.

Iron Chromite sand for casting has good high-temperature performance, mainly manifested as high temperature casting resistance, excellent slag resistance, small thermal expansion coefficient, outstanding thermal conductivity, no sharp corners in broken particles, and high strength. In addition, the moisture content and clay content of chromite sand are also important indicators of chromite iron sand.
