iron chromium oxide (FeCr2O4), a mineral comprised of chromium and iron oxide that is naturally found in the earth's mantle. When extracted, it is referred to as chrome ore. – Chromite is crucial for the production of ferrochrome, an alloying agent in manufacturing stainless steel. Chromite provides the corrosive resistance properties in stainless steel, making it an ideal material for use ...

The chromium ore concentrates of Kempirsai and Aganozero deposits used in present study had different ratio of iron and chromium content. The Reduction in CO gas atmosphere did not result in reduction of chromium and iron from spinels; however, it resulted in reduction of fines from the drying apparatus, where the particles of coke presented along with the particles of the .

Cost analysis of chrome ore reduction is one of the important issues facing ferrochrome producers in today's competitive environment. Much of this depends on quality and various ratios in the ...
