Chromite Wikipedia
Chromite is a crystalline mineral composed primarily of iron(II) oxide and chromium(III) oxide compounds It can be represented by the chemical formula of FeCr 2 O 4It is an oxide mineral belonging to the spinel groupThe element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr 2 O 4) AThis approach has not only resulted in the reduction of chrome losses (<12% Cr 2 O 3) but also the concentrator achieved a stringent target SiO 2 grade of 327% in the concentrate The approach adopted and practical problems encountered during the study are reported in this paper Keywords: chromite ore, characterization, QEMSCAN, gravityJournal of the Southern African Institute of Mining and Metallurgy
