Integrated lunar materials manufacturing process

The magnetic fraction which will contain the ilmenite and agglutinates is drawn toward the walls while the silicate tailings fall into the center tube 21 This process increases the reactive components ie the ilmenite and lunar agglutinates to about 8090 of the feed

The main objective of this thesis is to investigate the effect of the stability and nonNewtonian rheological properties of magnetite dense medium on the performance of dense medium cyclone DMC In addition the DMC separation mechanism the rheology of magnetite dense medium and the hydrodynamics of particle movement in non Newtonian fluids are also studied The tests carried out on a

Jul 04 2013 Beneficiation of alumina rich iron ore slimes is a major challenge for the Indian iron ore industry Considering the limits of gravity and magnetic separation processes in the relatively finer size range in terms of achieving adequate separation efficiency selective flotation with and without selective flocculation of iron ore slimes which is being used commercially in several countries

Magnetic composites exhibit distinct flux properties due to gradient interfaces The composites can be used to improve fuel cells and batteries and effect transport and separation of different species of materials for example transition metal species such as lanthanides and actinides A variety of devices can be made utilizing the composites including a separator an electrode for channeling
