Nickel sulphide ore subjected to this investigation was taken from the Orhaneli–Marmara district, where widespread chromite mineralization can be observed. Significant amounts of magnetite and chromite exist in the ore together with sulphide- and oxide-type nickel minerals.

Chromite ore | CrFeO4 - PubChem

The amount of beneficiation required and the techniques used depend on the ore source and end-use requirements. When the chromite is clean and mossive, only hand sorting of coarse material and gravity separation of fine material may be required. When the ore is lumpy and mixed with other minerals, heavy-media.
