Superconducting magnetic separator

In a continuously operating superconducting magnetic separator in which a mixture of particles of different magnetic susceptibility is led through the field of a stationary magnetic conducting magnet arrangement and subjected to the influence of the product of the induction B and its local field gradient grad B, and in which particles of a given susceptibility are continuously separated magnetically from the mixture by means of a carrier running through the magnetic field and are removed from the carrier outside of the influence of the magnetic field the improvement comprising:

• a. a magnet arrangement generating a magnetic field of large volume which penetrates the mixture moving past the field said magnet arrangement comprising at least two pairs of superconducting magnets arranged opposite each other on opposite sides of the transport path said magnets energized to have increasing field strength in the direction of transport;
• and
• b. a carrier including at least one common ferromagnetic grid associated with all pairs of magnets said ferromagnetic grid being moved through the magnetic field in close proximity to the mixture being transported transversely to the transport direction of the mixture, said ferromagnetic grid generating a field gradient.
