Pre-concentration of vanadium from stone coal by gravity …
The benefit of the pre-concentration process for vanadium extraction is shown in Fig. 6. Through the vanadium pre-concentration process, the acid consumption and heat consumption costs for producing 1 t V 2 O 5 decrease 7550 CNY and 2230 CNY, respectively. However, the pre-concentration process only requires 4770 CNY/1 t V 2 O 5.

concentration can facilitate utilization of resources below cut-off grade (0.5% V 2 O 5). Currently, over 60% of the stone coal resources are below the cut-off grade and therefore cannot be economically exploited (Deng et al., 2010). Gravity separation and flotation separation are effective methods of pre-

gravity from feldspar. This distinguishing property of fine mica particles was first reported by Iverson (1932). He managed to separate mica from feldspar by tabling. Later, Adair et al. (1951) also showed the possibility of concentration of mica in the Humphrey spiral. Therefore, this method is considered as an alternative method to mica ...
Gold Gravity Concentration
The object of gravity concentration is the separation of the heavy valuable mineral from the light worthless gangue. Complications are often introduced by the fact that various base minerals must be separated from one another, an ore being subdivided into several products. Most gold ores, however, only require separation into two parts—the ...

Mica's Specific Gravity: Meaning & Impact in 10 Industries
Mica generally has a specific gravity between 2.76 and 3.2. This means it is about three times denser than water. This measurement is crucial because it helps predict how mica will behave in both natural settings and industrial applications.
