Tribocharged electrostatic beneficiation of a lunar simulant and actual Apollo regolith has been shown to be successful under a high lunar vacuum in which various degrees of efficient particle separation and mineral enrichment of up to a few hundred percent were achieved. In this paper, electrostatic beneficiation of a lunar simulant at 1/6 g , as run on reduced gravity flights (RGFs), is reported. Enrichment of the target mineral ilmenite was achieved as high as 65 and 106% in the two RGF flights undertaken, showing that tribocharged electrostatic beneficiation is a viable process in the lunar environment. It was also shown that the efficiency of the separation was a factor in the orientation of the apparatus in the aircraft because the force of gravity was not perpendicular to the plane of the apparatus during the flight parabolas.
