Optimise chromite ore for maximum efficiency in ferrochrome production. Chromite ore is predominantly used in the production of ferrochrome – an alloy of chrome and iron containing between 50% and 70% chromium.
To optimally exploit this valuable and strategic raw material, numerous chrome ore beneficiation plants have been established. Most of these plants suffer chromite losses into the tailing. Decreasing these losses would not only improve the plant performance but also make the economics of the operations more attractive.
