The difference in specific gravity between the useful minerals of chromite and the associated gangue is very obvious, and gravity beneficiation is suitable. In fact, in the industrial application of chromite beneficiation, gravity beneficiation is the most widely used. Let me share with you the gravity beneficiation process of chromite ore.
Gravity separation of coal and ash is the most widely used beneficiation process (6). However, the efficiency of this process depends on coal washability, i.e., percentage of ash (and non-chemically bound sulphur) which may be separated by gravity from various size-fractions of coal.
The specific gravity of RE minerals is relatively high (2.9–7.2), while the density of gangue minerals (mainly silicate) is low. Therefore, gravity separation is an important technique for concentrating RE minerals. 51, 52 Extensively used gravity separation devices include shaking tables, conical separators, and spiral concentrators.
Gravity separation of bastnaesite has also had limited economic success. [Citation 66] However, gravity separation has been employed for REM beneficiation in heavy mineral sands processes, with separators such as FC, Knelson, Mozley Multi-Gravity Separator, spirals, and shaking tables serving as gravity pre-concentration stages.
