dc.description.abstractThe applicability of Mozley centrifugal force gravity separator (MGS) to fine fractions (-0.1 mm) of a low grade chromite ore (9.3 % Cr2O3) was investigated. The metal-screen analysis revealed that 83.9 % of the material ground under 1 mm for tests was in the +0.106 mm fraction containing 8 % Cr2O3. On the other hand, 16.1 % was in the-0.106 mm size fraction containing 16.12 % Cr2O3. The +0.1 and -0.1 mm fractions were used as feed for shaking table and MGS tests respectively. A saleable shaking table concentrate with low chromite recovery was obtained by shaking table tests. However, after some of the shaking table products were ground under-100 μm and concentrated with MGS, a chromite concentrate with 46.22 % Cr2O3 grade and 66.1 % Cr2O3 wt. recovery was obtained by the combination of shaking table and MGS. It was seen that MGS was an applicable beneficiation method at fine fractions for concentration of a low grade chromite ore. A principal flowsheet for the concentration plant was proposed.
