SEPARATION OF CHROMITE FROM OLIVINE BY ANIONIC …
Chromite and olivine samples were purified by magnetic separation and panning, washed with triple distilled water, and ground under 200 mesh by an agat mortar. Surface areas of chromite and olivine were measured as 0.4 and 2.8 m2/g, respectively. For adsorption tests, 0.2 g of chromite and 0.1 g of olivine were aged in 20 ml water overnight.

Philippine chromite ore beneficiation--samples tests
Chromite is of weak magnetism, so intensity magnetic separation has been used in some places but not all chromite can be separated by this intensity magnetic separation. The density of chromite ore is 4.3-4.8g/cm³,and it is a obvious difference with that of waste stone, so gravity separation can work very well for the chromite separation.
