  • Chromite Beneficiation Process

     · 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.

  • Chromium | Minerals Eduion Coalition

    Chromium (Cr) is a hard, bluish metallic element. The only ore of chromium is the mineral chromite and 99 percent of the world's chromite is found in southern Africa and Zimbabwe. Geologists estimate that there are about 11 billion tons of mineable chromite ore in the world, enough to supply the current demand for hundreds of years.
