It is estimated that the magnetic separation of 100 000 tons of lunar soil would yield 150-200 tons of iron. Agglutinates glass-bonded aggregates of soil fragments contain metallic iron which could be extracted by melting and made into powder-metallurgy products Romig and Goldstein 1976, Criswell 1981.

Jan 01, 1993 Magnetic Separation is a physical separation process that segregates materials in a mixture on the basis of magnetic susceptibility. Most of the actinides and their compounds and fission products are paramagnetic, and most host materials such as water, graphite, soil, and sand are diamagnetic.

Sep 15, 2014 The bulk susceptibility of the schoolyard soil before magnetic separation was 3.5 10 4 , and the captured and passed soils were 5.7 10 4 and 1.1 10 4 respectively. From this result, it was proved that magnetic separation of the soil is possible utilizing the difference of the magnetic susceptibility.

Magnetic separation. Iron particles are highly sensitive to a magnetic field, and can be extracted by passing lunar regolith over a rotating magnetic drum. Any particles containing iron would stick to the drum and are scraped off the other side, while the remainder fall through. Only about 2 of the lunar soil would adhere to the drum. A very ...

In the second method, the soil was magnetically sorted using a Frantz magnetic separator. The iron metal within agglutinates makes them magnetically suscepti-ble, and thus this step concentrated agglutinates e.g., 4,6. However, past workers noted that 1020 of the magnetic fraction is non-agglutinates, and 5 to 20
