Lunar beneficiationNatural concentrations of industrially valuable minerals are far less likely to be found on the Moon than on the Earth. But that is all the more reason for devising beneficiation processes to concentrate and extract the useful mineral components in lunar rocks and soils. As an example of a useful mineral that can be beneficiated, it has been estimated that ilmenite abundance accounts for 15 and 20 percent of the volume of the Apollo 11 and 17 basalts and 2 and 5 percent by volume in the Apollo 11 and 17 soils. Reduction of lunar ilmenite with hydrogen imported from Earth appears to one of the more practical schemes for obtaining lunar oxygen. While the reported concentrations are significant, a more highly concentrated ilmenite extract would improve the efficiency of the reduction process. The topics covered include electrostatic concentration, magnetic concentration, lunar soil sizing, and electrical sizing.
