2012-2-7 The chromite ore Cr/Fe ratio is of importance as it directly affects the alloy Cr grade whilst the gangue elements affect the melting energy and rate as well as the slag chemistry. The chromite spinel ore morphology can be described stoichiometrically as (Fe, Mg)(Cr,Al,Fe)2O4 and chromite ores often contain gangue elements of SiO2 and MgO.

2020-11-1 Despite the lack of evidence, non-self-similar distributions occurring after the complete failure (at the breakage probability of one) may largely correspond to the shattering events at excessive energy levels. Therefore, these non-self-similar curves indicate that excessive impact may shatter the chromite ore and the clinker particles differently.

2005-7-15 We investigated a method for delivering ferrous iron into the subsurface to enhance chemical reduction of Cr(VI) in chromite ore processing solid waste (COPSW) derived from the production of ferrochrome alloy. The COPSW is characterized by high pH (8.5−11.5) and high Cr(VI) concentrations in the solid phase (up to 550 mg kg-1) and dissolved phase (3−57 mg L-1).
