Improving the Quality of Ferruginous Chromite Concentrates ...

The low chromium-to-iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the chromium-to-iron ratio.

Modelling and optimization of clean chromite

In Turkey, chromite concentrating plants use gravity separation (shaking tables and spirals, etc.) 0.5 mm to beneficiate coarse (chromite), and the finer fractions are discharged as tailings. In most chromite plants, around 10-50 percent of total run-of-mine chromite is found to be –0.5 mm. The total amount of fine chromite gravity
