· The Cr:Fe ratio (chromiumtoiron mass ratio) of chromite affects the production of chromebased ferroalloys. Although the literature contains numerous reports related to the magnetic separation of different minerals, limited work concerning the appliion of magnetic separation to fine chromite from the Sukinda region of India to enhance its Cr:Fe ratio has been reported. In the present ...
The possibility of reduction of chromium and iron from complex oxides by gaseous carbon monoxide and solid carbon was investigated. 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 ...
