2017-11-23 · Different types of beneficiation techniques are using for chromite ores to remove gangue minerals from the chromite concentrations such as gravity separation, flotation or magnetic separation (Kroll-Rabotin et al, 2013). New generation gravity processing devices such as Mozley Multi Gravity Separator (MGS), Falcon concentrator and Knelson Concentrator are promising technologies for the recovery of chromite at fine sizes (Singh et al. 1997, Rama Murthy et al. 2010). Falcon concentrator, one of the enhanced gravity separators, can generate high ‘G’ force up to 300 which can effectively separate very fine heavy chromite particles from the gangue mineral particles. Over the last decade, EGS have found wide acceptance to mineral industries for concentration of fines and ultra-fine minerals in particular to precious metals such as Au, Ag, Pt.
