Using inert grinding media, the flotation has become selective towards chalcopyrite and arsenopyrite than pyrrhotite at the initial stages of flotation. Flotation behavior of pyrrhotite could be the synergistic effects of the galvanic interactions of two-minerals-and-grinding-media and mineral-to-mineral systems, and the proposed mechanism of oxidation by magnetite particles.

Preparation of Al

Volcanic rock found in the Longgang Volcano Group in Jilin Province of China has properties essentially similar to Apollo lunar soils and previously prepared lunar soil simulants, such as Johnson Space Center Lunar simulant and Minnesota Lunar simulant. In this study, an electrochemical method of preparation of Al-Si master alloy was investigated in 52.7 wt.%NaF-47.3 wt.%AlF3 melt adding 5 wt

NASA Offers Reward for Extracting O2 from Moondust

DoubleWhopper writes Break out the duct tape and paper clips.NASA has announced a $250,000 reward to the first team of scientists to invent a way to extract breathable oxygen from lunar soil. Wired reports, Inventors who attempt the Moon Regolith Oxygen (or MoonROx) challenge will have just eight hours to extract at least 11 pounds of breathable oxygen from a simulated form of lunar soil.

Ionic liquid electrochemical processing of reactive

This is very low compared with industrial Al electrorefining and Al electroplating using the National Bureau of Standards bath, which require 15-18 kWhr/kg-Al and 18 kWhr/kg-Al, respectively. However, due to low solution conductivity the power consumption increases significantly with increased anode-cathode spacing.

Aluminothermic Reduction

Aluminothermic reduction-electrolysis using an inert anode process is proposed to extract oxygen and metals from Minnesota Lunar Simulant-1 (MLS-1). Effective aluminothermic reduction between dissolved MLS-1 and dissolved metal aluminum was achieved in cryolite salt media. The product phases obtained by aluminothermic reduction at 980C for 4 h were Al, Si, and AlSUB5/SUBFeSi, while the

Platinum does appear to be a suitable anode material (Haskin et al. 1990). The second type of material involves a steady-state equilibrium. An iron skull container or cathode could be formed by balancing the heat generated by the electrolysis with heat lost to the surroundings to form a solid skin of product or feedstock enclosing the silicate melt and metal product.

Bock et al. (1979) have studied the retrieval of lunar materials to various points in space, using chemical rockets burning lunar LOX and aluminum powder or terrestrial H 2. The objective is to transport from the Moon to cislunar orbital space many times more mass than could be supplied from Earth at equal cost.

Electrolysis of lunar materials (Henry Spencer; MA Lloyd)

There have been quite a few experiments using Earth materials with roughly lunar compositions, although I'm not sure it's ever been tried on actual lunar soil. You get fairly pure oxygen at the anode, and mostly iron and silicon at the cathode.

The production of oxygen and metal from lunar regolith

2012/12/1The lunar highlands are composed of predominantly anorthositic rocks and contain more than 90% by mass plagioclase in the form of calcium-based anorthite (CaAl 2 Si 2 O 8) and small quantities of magnesium- and iron-bearing minerals such as pyroxene ((Mg,Ca,Fe)SiO 3) and olivine ((Mg,Fe) 2 SiO 4); and the lunar mare is composed of basaltic lava flows which contain varying
