SYSTEM FOR EXTRACTING WATER FROM LUNAR REGOLITH AND ASSOCIATED METHOD
The system extracts water from lunar regolith and includes a regolith intake having a digging bucket that collects lunar regolith soil and a gravel separator that separates and discharges gravel and passes a mixture of ice-regolith powder having ice grains that are about 10-100 microns along the conveyor. A pneumatic separator receives the ice-regolith powder and pneumatically splits the ice-regolith powder into streams of different sized lithic fragments and ice particles per the ratio of inertial force and aerodynamic drag force of the lithic fragments and ice particles. Each split stream may include a magnetic separator that separates further the magnetic and paramagnetic lithic fragments from ice particles to discharge up to 80 percent of lithic fragments to slag.

PROCESS FOR DRY BENEFICIATION OF FINE AND VERY FINE IRON ORE BY SIZE AND ELECTROSTATIC SEGREGATION
Systems and methods for the beneficiation of fine and very fine particles of iron ore are disclosed. The system includes a first triboelectric electrostatic belt-type separator (BSS) which receives and processes a stream of particles with a median particle size (d50) less than 75 microns to generate an iron rich concentrate. The system and method is water-free and carried out in a totally dry metallurgical route. The system also includes at least one air classification device that receives and processes a feed stream of particles to provide the stream of particles with a median particle size (d50) that is less than 75 microns. The system may also include a dryer and de- agglomeration system that receives a feed stream of particles and processes the feed stream of particles to provide the particle stream with a moisture of less than 2%.

METHOD FOR SEPARATING FINE PARTICLES IN SOIL USING CATIONIC MAGNETIC NANOPARTICLES
The present invention relates to a method of separating fine particles in soil using cationic magnetic nanoparticles, and more particularly, to a method of separating fine particles (clay, silt, etc.) that have adsorbed contaminants such as heavy metals or radioactive nuclides in soil using cationic magnetic nanoparticles.
According to the present invention, contaminants such as heavy metals or radioactive nuclides selectively or irreversibly adsorbed to fine particles (clay, silt, etc.) in soil may be economically and efficiently separated. Therefore, the present invention may be effectively used to restore soil in residential areas that are contaminated with radioactive nuclides in serious accidents such as the Fukushima Daiichi nuclear disaster as well as facility sites contaminated with heavy metals or radioactive nuclides.
