<p>Magnetic separation apparatus is disclosed for removing particles from a fluid-particle mixture, characterized by the provision of a plurality of parallel relatively thin-section matrix separator elements arranged within and parallel to the direction of a magnetic field, and flow establishing means for causing the mixture to flow in parallel flow paths through the matrix elements, respectively, in thickness directions transverse to the direction of the magnetic field. The matrix elements may be parallel spaced polygonal elements, or concentrically arranged annular elements. Preferably the matrix elements include a hollow non-ferromagnetic canister, and a mass of relatively short ferromagnetic fibers havin a length of about 1-10 millimeters packed in the canister with a density of at least 8 percent by volume relative to the volume of the canister. Pole pieces may be provided having pole faces with projections thereon for concentrating the magnetic flux longitudinally through the longitudinally arranged matrix elements.</p> |
