Evaluation ofTribocharged Electrostatic Beneficiation ofLunar Simulant ...

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.

22.4: Beneficiation - Chemistry LibreTexts

Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue. The latter can be suspended in a stream of water and flushed away.
