Different Pathways for Cr(III) Oxidation: Implications for

Hexavalent chromium contamination is a global environmental issue and usually reoccurs in alkaline reduced chromite ore processing residues (rCOPR). The oxidation of Cr(III) solids in rCOPR is one possible cause but as yet little studied. Herein, we investigated the oxidation of Cr(OH)3, a typical species of Cr(III) in rCOPR, at alkaline pH (9–11) with δ-MnO2 under oxic/anoxic conditions

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.

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).
