Abstract
A method and apparatus for recovering magnetic particles from a fluid stream is provided. The fluid is contacted with a ferromagnetic element to cause attraction and collection of the particles. The ferromagnetic element is then heated to a temperature near or above the Curie temperature of at least one of (1) the ferromagnetic element and (2) collected magnetic particles. The collected magnetic particles are then disengaged from the ferromagnetic element. Preferably the ferromagnetic element is disposed in an applied magnetic field and the heating is preferred by passing alternating electric current through the element thereby causing sufficient vibration to disengage the particles.
