Abstract: The invention relates to a matrix ring magnetic separator the induction bodies of which are formed by sieve nettings which are arranged vertically and stacked behind one another in the direction of the magnetic field in such a way that the intersections of the wires of one sieve netting are located on the free field of the adjacent sieve netting resulting in the formation of sieve netting assemblies which are springy in themselves in the direction of the magnetic field. Even at very high field strength gradients such a magnetic separator is distinguished by good possibilities for cleaning and can also be produced economically.

Abstract: The invention relates to a coil arrangement for a magnetic separator having a strong field, in which the solenoid coils are provided in the first part only of the length of the housing and a magnetic shunt is arranged between the first and second parts of the length of the housing. A considerable reduction in the coil weight is achieved by such a construction.

Abstract: The invention relates to apparatus for separating ferromagnetic particles from a slurry, in which the slurry passes through a tunnel-shaped channel which is surrounded by a magnet coil the iron yoke of which is constructed asymmetrically in such a way that the magnetic field strength in the channel increases from the top towards the bottom.
