During the beneficiation of chromite ore of Sukinda region, approximately 50% (by weight) of the total feed is discarded as tailing which contains a significant amount of chromite. Several studies have focused on reduction of chromite losses in the beneficiation plant tailing (Rao et al., 1987, Raghukumar et al., 2009, Tripathy et al., …
