The chromite ore is separated by (1) Magnetic Separation (2) Froth floatation (3) Gravity separation (4) A & C both
As we learned
Magnetic separation -
If ore and not the gangue or the gangue and not the ore is attracted by a magnet, the two can be separated by this method
- wherein
FeO, Cr2O3, having the impurities of SiO2.
Chromite ore has impurity of SiO2 which can be separated by magnetic separation as well as gravity separation.
