Chromite Beneficiation Process

Mar 19, 2017  Chromite Process Summary. This flowsheet is very effective due to the ability to remove the high grade chrome with very little grinding on each pass through the mill. In this way, grinding takes place with a large number of small reductions followed by immediate removal of the liberated chrome into a high grade concentrate.
