A new method for gravity separation: Vibrating table ...

2019-3-18  Chromite liberation of high grade ore was starting below 1000 μm and reaching up to approx. 75–80% below 425 μm. Majority of the chromite (Cr 2 O 3) was reported as free and liberated from the host minerals providing a more convenient angle for concentration methodology design. Therefore, lump particles in the original sample batch were ...
