The ball mill treatment reduced chromite grains greater than 15.77 µm down to sizes less than 11.15 µm in diameter, and thus released chromite-bound Cr(VI) for sulfide reduction. Magnesioferrite encapsulated Cr(VI) was released and reduced similarly with grain size change from 15.77 to 37.5 µm to below 15.77 µm.
