South African chromite mines generally recover 10–15% lumpy/coarse ore (15 ≤ typical size range ≤ 150 mm) and 8–12% chip/pebble ore (6 ≤ typical size range ≤ 15 mm), with the <6 mm fraction accounting for the remainder of ore . The beneficiation of lumpy, chips/pebble chromite is achieved by crushing, screening, and dense media ...
