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 .

A cleaner method for preparation of chromium oxide

01/01/2017  A new leaching process for preparing chromium oxide from chromite was studied in this paper, using Cr(VI) extracted from the remediation treatment of chromite ore processing residue (COPR) as an oxidant. Thus, the “detoxification” of deposited COPR could be achieved and no new Cr(VI)-bearing substances would be generated in preparation process of chromium oxide. Thermodynamic analysis

Dissolution and reduction of chromite ore in ferrochromium ...

chromite ore was fed into the molten slag, and was followed by reduction of iron and chromium oxides. Due to the fact that the chromite ore was fed in granular form, as expected, a greater contact area was created which influenced the dissolution / reduction reaction between the ore and the slag. The slag composition played a significant role in the dissolution and reduction process. The ...
