Chromite specific gravity is 4.2~4.8, and it has weak magnetic properties. Therefore, gravity separation and magnetic separation can be used.
Common chromium spinel minerals in chromium ore in my country include chromite, aluminum chromite, and chromium-rich spinel.
The difference in specific gravity between the useful minerals of chromite and the gangue is obvious, so gravity beneficiation is suitable.
The chromite beneficiation process is gravity separation. The pieces of equipment are mineral jigs, shaker table, spiral concentrator, etc.
