• 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.

    For the 2nd reduced gravity flight, the objective was to test the beneficiation at 3 higher voltages than the 1st flight, namely, +/13kV, +/ 15 kV, and +/20 kV using a simulant mixture. The first lesson learned from the 1st flight was that the regolith needed to be properly dried prior to the flight as the presence ofmoisture on the surface ofthe particles reduced the acquired charge.
