Patent ID: 8342336

Claim:
A method for the extraction of non-magnetic ores from a pulp possessing non-magnetic ore particles and having a solid fraction of at least 30 percent by mass, wherein the pulp flows through a reactor in flow direction, the method comprising: supplying the pulp with magnetic or magnetizable magnetic particles to which the non-magnetic ore particles bind to form ore/magnetic-particle agglomerates, moving the ore/magnetic-particle agglomerates by means of a magnetic field into an accumulation region of the reactor, discharging the ore/magnetic-particle agglomerates from the accumulation region of the reactor, breaking the bonds between the ore particles and the magnetic particles of the ore/magnetic-particle agglomerates to separate the ore/magnetic-particle agglomerates into ore particles and magnetic particles, and treating the separated magnetic particles in such a way that, upon subsequent interaction with non-magnetic ore particles, they form new ore/magnetic-particle agglomerates.
