In this investigation, we optimize the grinding circuit of a typical chromite beneficiation plant in India The runofmine ore is reduced to a particle size of less than The ball mill treatment reduced chromite grains greater than 1577 µm down to sizes less than 1115 µm in diameter, and thus released chromitebound Cr(VI) for sulfide reduction Magnesioferrite encapsulated Cr(VI) was released and reduced similarly with grain size change from 1577 to 375 µm to below 1577 µmA New Method (Ball Milling and Sodium Sulfide) for Mechanochemical
The single sized fraction of a − 425 + 250 μm feed of material obtained from our laboratories was ground for different lengths of time in a laboratory ball mill The specific rate of breakage, (S i ), for dry milling was determined to be 028 min −1,while the S i value for wet grinding was 056 min −1 Grinding/milling process is applied for further valuable mineral liberation to less than 1mm followed by concentration of chromite valuable particles through gravity separation methods such asPerformance optimization of an industrial ball mill for chromite
