We examined the possibility of applying magnetic separation method using the superconducting magnet, which can process a large amount of the soil in high speed, to the soil decontamination and volume reduction of the radioactive cesium contaminated soil.

  • Magnetic separation for environmental remediation ...

    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. Magnetic separation methods can be used to extract the actinides from these hosts, concentrating

  • Magnetic separation for soil decontamination - UNT

    High gradient magnetic separation (HGMS) is a physical separation process that is used to extract magnetic particles from mixtures. The technology is used on a large scale in the kaolin clay industry to whiten or brighten kaolin clay and increase its value. Because all uranium and plutonium compounds are slightly magnetic, HGMS can be used to separate these contaminants from non-magnetic soils.
