Chromite: The only mineral ore of chromium metal

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. 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 an overview ScienceDirect Topics

Chromite ore with a small amount of coke is ground wet in a ball mill, after which the resulting slurry is de-watered. It is mixed with a binder before being fed into a rotating drum or disc pelletizer, where it forms balls. Pelletizing occurs due to the rolling motion of the pelletizer without the application of pressure.

Chromite Chromium Ore, Properties, Uses and Occurrence

Jul 02, 2019 Chromite is an oxide mineral that an iron chromium oxide with formula: FeCr2O4. It is belonging to the spinel group. Chromite is the most important ore of chromium. Crystals are uncommon, but when found they are octahedral. Chromite is usually massive or in the form of lenses and tabular bodies, or it may be disseminated as granules.

The main component of the chromium ore is chromite FeCr 2 O 4. The ores extensively dispersed in natural deposits and generally contaminated with Mg, Si, Al, and O. The chromium metal commercially separated by oxidizing chromite ore to Cr 2 O 3, then the metal is attained by heating the Cr 2 O 3 in the presence of Al or Si [5,6].
