Abstract (en)

[origin: EP2090367A1] The method involves providing a pulp (P), which continuously flows via a reactor (1) in a flow direction. Magnetic- or magnetizable magnet particles are supplied to the pulp, where the particles form ore-magnetic particle-agglomerates with non-magnetic ore particles. The agglomerates are moved into an accumulation region (4) of the reactor by a magnetic field, and are separated into ore particles and magnetic particles. The separated magnetic particles are hydrophobized such that new ore magnetic particle agglomerates are formed during a new reciprocal effect with the non-magnetic particles. An independent claim is also included for a device for continuously producing non-magnetic ores from a pulp.
