Abstract

A magnetic separator for separating magnetizable particles from a fluid is described. The separator is of the type compris-ing a separating chamber having an inlet and an outlet with means for establishing an axial magnetic field within the chamber.
Two or more matrix elements are stacked axially within the chamber. Fluid control means is provided for dividing a stream of fluid containing magnetizable particles supplied to the inlet of the chamber into two or more portions and directing each portion axially through a respective matrix element and thence to the outlet. For a given slurry feed amount, a greater matrix element area is provided. The matrix elements may be in the form of spaced annuli, the fluid portions being fed radially between adjacent first and second elements, axially through the second element and then radially between the second element and a third element adja-cent thereto on the opposite side to the first.
