This study aimed to evaluate the chromite recovery from shaking table tailings of Forumad plant by a dry highintensity magnetic separation. The average feed grade of chromium trioxide (Cr2O3) was % by XRF. Also, different mineral phases were determined by XRD, identifying the presence of Chrysotile, Augite, Albite, Chlorite and Chromite.

The low chromiumtoiron 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 chromiumtoiron ratio.
