Magnetic Separation. Magnetic separation is used to extract slightly magnetic radioactive particles from host materials such as water, soil, or air. All uranium and plutonium compounds are slightly magnetic while most host materials are nonmagnetic. The process operates by passing contaminated fluid or slurry through a magnetized volume.

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 permeability of soil

Magnetic Permeability. In this unit we learn magnetic permeability that is the quantity of ability to conduct magnetic flux. The soil permeability is a measure indicating the capacity of the soil or rock to allow fluids to pass through it. In soils, the ease with which gases, liquids, or plant roots penetrate into or pass through a layer of soil.

S.G. Frantz’s standard proprietary grids are effective for most applications, exemplifying a principle revealed early by Mr. Frantz: For effective magnetic separation, the size of the collecting edge should be on the same order of magnitude as the size of the particles to be captured. This configuration offers several advantages: The width of the strip is aligned with the background magnetic ...
