V-6 Mining and Beneficiation of Lunar Or RICHARD J WILLIAMS, DAVID S McKAY, DAVID GILES AND THEODORE E BUNCH The beneficiation of lunar plagioclase and ilmenite ores to feedstock grade permits a rapid growth of the space manufacturing economy by maximizing the production rate of metals and oxygen
§ 423 Separating Minerals by Electrostatic Beneficiation Minerals come in grains For example, a scoop of lunar dirt will typically contain a number of minerals, but the different minerals will come in the form of different grains, each grain being a glob of mostly one particular mineral
At that time, an ilmenite beneficiation process, which was normally achieved with cross-belt separators, was tested with a full-size machine The performance was not good because only a single , Read more Post navigation Older posts Newer posts ← Previous Page 1 , Page 5 Page 6 Page 7 .
