Evaluation ofTribocharged Electrostatic Beneficiation

2020-8-6  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.
