The second flight, using the amended simulant, found that ilmenite could be enriched by up to 106% following a single pass (approximately 10 w t. % to 20.6 w t. %), although only 23.9% of the original ilmenite was recovered (Quinn et al., 2012). It appears, however, that the authors have not accounted for the pre-existing ilmenite in NU-LHT …

About Rutile Ore. Rutile is one of the main minerals containing titanium. It is brittle, with a hardness of 6-6.5 and a density of 4.2-4.3g/cm3. Those rich in iron, niobium, and tantalum will increase in density, and the higher ones can reach more than 5.5g/cm3. It can be dissolved in hot phosphoric acid.

Beneficiation of lunar ilmenite One of the most important commodities lacking in the moon is free oxygen which is required for life and used extensively for propellent. Free oxygen, however, can be obtained by liberating it from the oxides and silicates that form the lunar rocks and regolith. Ilmenite (FeTiO3) is considered one of …

enrichment of ilmenite in the lunar regolith feedstock is desirable. Triboelectrification and electrostatic beneficiation of minerals using a parallel-plate separator is a well-known technology successfully used to separate coal from minerals [6], quartz from feldspar, phosphate rock from silica sand, and phosphorus from silica and iron ore [7].

Experiments to evaluate the performance of the ilmenite were carried out in a laboratory-scale cylindrical fluidized bed. Losses of the ilmenite were investigated by mixing and recovering the ilmenite using two different coal samples of 13.2–50 mm particle size. Density tracers were used to determine the écart probable moyen (EPM).
