Chromium processing Britannica

Although chromium occurs in many minerals, the only ore exploited commercially is chromite. This spinel mineral is ideally composed of ferrous oxide and chromic oxide with the chemical composition FeO · Cr 2 O 3, but it is often found in nature with magnesia (MgO) substituting for FeO and alumina (A1 2 O 3) or ferric oxide (Fe 2 O 3) substituting for Cr 2 O 3.

Chromite- mineralogy and processing ScienceDirect

Jan 01, 1988· The chrome ores in the Kempirsai Massif region in the U.S.S.R. have, until recently, been mined as hard, lumpy ore, with no need for beneficiation. Lower Chromite---mineralogy and processing 239 grades now make beneficiation of much of the ore essential, gravity concentration (Heavy Medium Separation and tabling) being used with flotation [9].

Chromite Wikipedia

Chromite is a mineral that is an iron chromium oxide.It has a chemical formula of FeCr 2 O 4.It is an oxide mineral belonging to the spinel group.The element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr 2 O 4). A substitution of the element aluminium can also occur, leading to hercynite (FeAl 2 O 4).

Chromium processing Britannica

Chromium processing, preparation of the ore for use in various products. Chromium (Cr) is a brilliant, hard, refractory metal that melts at 1,857 °C (3,375 °F) and boils at 2,672 °C (4,842 °F). In the pure state it is resistant to ordinary corrosion, resulting in its application as an electroplated
