How to Recover Chromite

Oct 21, 2017  Chromite concentrates were as high as 55 pct Cr2O3 with a Cr-Fe ratio >2. Recirculating loads between the table and the Bartles-Mozley separator were 250 pct, which was predicted by the locked cycle test. Sand tailings from the Bartles-Mozley assayed between 2.9 and 3.3 pct Cr2O3, which was better than the bench tests.
