The world chromium ore production originates from the mineral chromite (a chromiumiron oxide) in the rock chromitite. The majority of the chromium ore resources of the world are to be found in the Bushveld Complex of South Africa and the Great Dyke of Zimbabwe, where it occurs as numerous thin stratiform chromitite layers.

It is therefore common to recover only 10–15% lumpy ore (15–150 mm) and 8–12% chip/pebble ore (6–15 mm) during the beneficiation process. The remaining ore would typically be in the <6 mm fraction, and would usually be crushed and/or milled to <1 mm and

Liberation was measured by grain counting and was performed on all the size fractions. This ore began to show chromite liberation around 20 mesh and was nearly liberated at 65 mesh.
