Chrome Ore Beneficiation Process Chromite Processing ...

3.2 Gravity separation process The density of chromite ore is slightly higher than that of its other magnetic gangue ore. Therefore, the separation of ferrochromium from other minerals can be realized by gravity separation. Use spiral chute to separate the concentrate process tailings and the scavenging process concentrate respectively.

Gravity separation of a UG-2 ore secondary sample for the ...

2012-04-01  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. Analysis of the chromite-rich stream showed that it could ...

Chromite - Wikipedia

Chromite is found as orthocumulate lenses of chromitite in peridotite from the Earth's mantle.It also occurs in layered ultramafic intrusive rocks. In addition, it is found in metamorphic rocks such as some serpentinites. Ore deposits of chromite form as early magmatic differentiates. It is commonly associated with olivine, magnetite, serpentine, and corundum.
