The most commonly used beneficiation methods for chromite ores are the gravity methods, such as the shaking table, jig, spiral and Reichert cone methods. The present work deals with the geologic studies that, coming after prospection, lead to the evaluation of the chromite ore quality and to planning and/or improvement of beneficiation plants.

Chromite was generally observed as circular-angular. Scattered and banded chromite grains within the ores were partially fractured as a result of deformation. The average size of free and individual chromite grains was measured between 0.09 and 0.30 mm (Fig. 3 a-d). Fig. 3. Chromite (cr) and serpentinised (sp) olivine (ol) grains observed

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 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

Chromite ore beneficiation. Disclosed is a process for beneficiating chromite ore. The process can also be used to remove SO 2 from SO 2 -air mixtures which would ordinarily be vented. The chromite ore is pulverized and preferably mixed with sodium sulfate. Ammonium carbonate can also be added for subsequent vaporization to increase porosity.
