Gravity separation relies on the difference in density between chromite and other minerals, while magnetic separation uses magnetic properties to separate the ore. Flotation involves the use of chemicals to selectively separate chromite particles from the rest of the ore. ( Chrome Plant Process Flow Explained - Flotation machines )
