    摘要: In a device and a method for extracting non-magnetic ores from a pulp comprising non-magnetic ore particles and having a solid fraction of at least 30 mass percent, the pulp flows continuously through a reactor in the direction of flow and magnetic or magnetizable magnet particles that form ore magnetic particle agglomerations with the non-magnetic ore particles are added to said pulp. The ore magnetic particle agglomerations are moved by a magnetic field into an accumulation range of the reactor, and are then discharged out of reactor range and separated into ore and magnetic particles. In a device and a method, the separated magnetic particles are treated, in particular hydrophobized, such that during a new interaction with non-magnetic ore particles, new ore magnetic particle agglomerations are formed. Accordingly, a high yield of ores can be obtained and the mine can be operated in an economical and environmentally friendly manner.
