Magnetic separation of the second kind: magnetogravimetric, magnetohydrostatic, and magnetohydrodynamic separations.
IEEE Trans Magn 1976 Sep; 12(5):455-462
Magnetogravimetric, magnetohydrostatic, and magnetohydrodynamic separation techniques can be classified as magnetic separations of the second kind. Ordinary magnetic separation relies on the inherent magnetic susceptibility of the material to be separated. When the medium of separation rather than the separated particles is made magnetizable, a new system of separations can result. In magnetogravimetry, a colloidal solution of a ferro- or ferrimagnetic substance acts as the separation medium. Magnetohydrostatic separations are conducted in an aqueous solution of a strongly paramagnetic salt. Magnetohydrodynamics applies the faraday effect on suspended conducting materials in an electrolytic solution placed in crossed electric and magnetic fields. The principles underlying the three separation techniques are discussed.
