Chromite ore beneficiation: prospects and challenges
Idiomorphic chromite is the only ore mineral appearing in economic quantities. The average content of the ore is 26% Cr 2 O 3 and the Cr/Fe ratio is 1.55. The Kemi chromium mine is an open-pit mine with a waste rock to ore ratio of 5.5:1. At Kemi, the ore from the mine contains 11% iron and 25.5% Cr 2 O 3.beneficiation, one of them is using magnetic separator. Chromite sand sample obtain from Konowe-Southeast Sulawesi have low grade, so it needs process to enrichment Cr:Fe Ratio.

Process optimization of a chrome ore gravity concentration plant
India has limited resources of chromite. To optimally exploit this valuable and strategic raw material, numerous chrome ore beneficiation plants have been established. Most of these plants suffer chromite losses into the tailing. Decreasing these losses would not only improve the plant performance but also make the economics of the Generally for processing chromite ores, different types of gravity methods are employed after crushing, grinding followed by classification.
