    S C Maulik & K K Bhattacharyya. National Metallurgical Lab oratory, Jamshedpur, India. Abstract. In order to produce directly marketable chrome ore for export and domestic industries, most of the chromite ore beneficiation plants in Sukinda region treat selected rich ores with rejection of huge quantities of low and sub-grade ore (10-38% Cr203). Beneficiation is mostly limited to

    Beneficiation of a low grade chromite ores is an essential step towards optimum utilization of natural resources. Some of the old practices like hand-picking, size reduction and screening are still in use to upgrade and prepare chromite ore for use in the industry. During mining, ferruginous and siliceous chromite ore fines are created as
