  • 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.WO1990004656A1 Refining of ilmenite by removal of excess,The presence of chromite in significant amount in ilmenite downgrades the market value of the ilmenite. A substantial amount of the chromite may be removed, firstly by a reduction step, secondly by a leaching, aeration or oxidation roasting step and finally by a physical separation step.
