Evaluation of Advanced Gravity and Magnetic
Multi gravity separator (MGS) is such an equipment which uses enhanced gravitational force for processing ultrafine particles. In the present study, a laboratory Mozley MGS was used for upgrading a low grade chromite ore assaying 26.8% Cr2O3. The chromite ore under study contained gangue minerals such as olivine, serpentine, chrysotile and ...

Concentration Studies on Chromite Tailings by Multi Gravity Separator
In this study, a representative sample was obtained from Uckopru mine in Türkiye in order to beneficiate fine-sized chromite tailings. Physical and chemical analyses showed that while the whole tailings contained l2.80%Cr2O3 ( by weight), the particle size fraction of minus 38 microns contained 25.20%Cr2O3 (33.20% by weight) and the particle size …
