2020-5-6 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 magnetite.

2012-4-1 Gravity separation of the chromite and silicate particles prior to secondary grinding was investigated with a spiral concentrator. Laboratory cleaner spiral tests were conducted on a plant sample from a secondary ball mill feed, to determine whether a chromite-rich stream could be removed and discarded from the process prior to milling.

The wide difference between the density of chromite (high) and quartz (low) makes it amenable to gravity separation. The Cr/Fe ratio versus size plot (Fig. 4) and sink and float studies of individual fraction demonstrate that gravity separation by tabling can be a preferred method for beneficiation of the ore. For tabling study, the sample is classified into two size fractions, viz. − 1000 + 100 µm and − 100 µm.

2013-12-24 Generally for processing chromite ores, different types of gravity methods are employed after crushing, grinding followed by classification. The Tata Steel Chrome Ore Beneficiation (COB) plant, designed to produce concentrate of +46% Cr2O3 with a recovery of 70% from a feed of 30-35% average Cr2O3. Presently the COB plant produces 50 tph of tailings analysing 17% Cr2O3, which is high. This

2020-9-25 Gravity Separation. From the point of production practice, the gravity separation is still the main chrome extraction method in the world method now, which uses the loose stratification in the water medium. At present, the gravity separator used in the chromite ore processing includes the shaker table, jig, spiral chute and centrifugal separator.

2013-12-24 Chromite: Chromite occurs as euhedral to subhedral crystal grains, rarely angular and elongated grains are also noticed. Occasionally chromite grains were fractured. Chromite is more enriched in Fe than normal as alternation product from chromite. Rarely the alteration of chromite leads to box-work type texture (Fig.4e).
