An arcuate shaped magnetic system is housed in a fixed cryostat within a rotating drum. A slurry containing magnetizable particles is charged into an operating area defined by the magnetic system at the lower part of the drum and magnetic particles adhering to the drum are removed as the drum rotates the same to a discharge location. The cryostat has an outer wall which conforms to the shape of the drum and houses a sector-shaped refrigeration tank. The refrigeration tank has an arcuate wall section conforming to the shapes of the cryostat wall and the drum and is positioned in close proximity to the outer cryostat wall only in the operating area in order to minimize inward heat transfer.

High intensity magnetic field drum separator

A magnetic separator, in particular a drum separator, includes a magnetic system having a plurality of magnets. Each of the magnets produces an open field directed toward a separation zone which, in a drum separator, extends axially of the drum outside of the surface of the drum. The magnets may include conductive coils, preferably superconducting coils, which are traversed in the same direction by current and which include an iron-free core. The average center-to-center spacing of the coils is a maximum of 25 times the spacing between the coils and the separating zone and is preferably in the range of 15:1 to 10:1. The coils are elliptical and have major and minor axes which decrease from the outermost coil winding to the innermost coil winding, with the distances between the windings being greater along the major axes than along the minor axes.
