Characterization and Beneficiation of Anka Chromite Ore ...

2013-12-24 · Beneficiation operations typically serve to separate and concentrate mineral values from waste materials, remove the impurities or prepare the ore for further refinement. 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.. Chromite ore is beneficiated for processing using several methods, depending on the ore source and the end use requirements. Coarse clean ore is hand sorted, while the fine clean ore is gravity separated. Lumpy ore mixed with host rock may require heavy medium separation. If chromite
