chromite mineral concentratio

CONCENTRATION OF CHROMITE BY MEANS OF MAGNETIC

Chromite is primarily used as a refractory material. For this purpose, the Cr 2 O 3 content of chromite should be more than 45%. Hence, concentration of chromite is often required. It is usually performed by gravity methods based on differences between the densities of chromite and gangue minerals, especially serpentine and olivine.

Chromite: The only mineral ore of chromium metal

What is Chromite? Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4).It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or weathering.

Improving the Quality of Ferruginous Chromite Concentrates ...

The low chromium-to-iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the chromium-to-iron ratio.
