CHARACTERIZATION AND BENEFICIATION OF ANKA CHROMITE …

Beneficiation activities do not change the mineral values themselves other than by reducing (crushing and grinding) or enlarging (pelletising and briquetting) particle size to facilitate further processes.[7]. Chromite ore is beneficiated for processing using several methods, depending on the ore source and the end use requirements.
