Chrome ore beneficiation. Most of the chrome ores around the world are beneficiated by gravity concentration techniques. A conventional chromite ore beneficiation process plant (Figure 3) consist of two sections: > Communition (for preparing the material for the subsequent unit operations) > Concentration (classification and beneficiation).
