It is known to use magnets under the action of magnets in the magnetic contact separator, in which inner zones between the bodies made of magnetic and one or two drums made of non-magnetic material are arranged with large material concentration zones. Generated below 40 ßer magnetic field strength,
half of the drum are containers for collecting the material to be separated is placed in a water particle of a magnetic and non-magnetic mixture in the vessel on the sections with the material. The material to be separated is given a magnetic effect. When flowing through the brought into the action zone of the magnet. Pulp through the zones with a high magnetic field strength The particles of the magnetic material are attracted to the drum and transported over the we-minerals including the weakly magnetic kung zone of the magnet, where they are converted into particles of hematite, ilmenite and others

It is difficult to remove the particles from the non-magnetic material from the container and into a container for 50 articles of a material which transports highly non-magnetic material and from there has magnetic properties, which leads to just as large (e.g. German patent specification 653 246).

Due to the uniform magnetic field strength, the magnetic drum separator achieves with two drums a better division of the material.
