Chromite tailings are generated from chrome ore beneficiation plants, containing substantial quantities of ultrafine particles. Generally these ultrafine particles of chromite cannot be treated effectively using conventional beneficiation methods, because of limitations in particles size being treated by these processes.

are beneficiated in chrome ore beneficiation plants in order to obtain high-grade concentrates (Cr2O3: >45wt%). During beneficiation, approximately 50wt% of the total feed is dis-carded as tailings which contain significant amounts of chromite. Several studies have been focused on recovering chromite from the plant tailings [3−4].
