WHAT IS Chrome ore: Chromite is an oxide mineral composed of chromium, iron and oxygen (FeCr2O4).Its color is dark gray to black with a metallic to sub metallic luster and a high specific gravity. �Chromite is important because it is the only economic ore of chromium, an essential element for a wide variety of metal, chemical and manufactured products.

 

Chromite grades:

  • High chrome- Cr2O3>46% (46-55) - use in Metallurgy
  • High iron - >40 Cr2O3> 46 - use in chemical industry
  • High aluminum -33 38 – use in refractory industry

 

Chromite usages

  • Main usages: Metallurgy-chemical industry-refractory industry
  • Chromium is an important ingredient in Steel; it increases the hardness and toughness of the Steel, and helps reduce its chemical erosion over time. Chromium is also vital in the aerospace industry because it is used to anodize the aluminum that is used to build aircrafts and related equipment. Chromite is an important refractory material.
