    摘要: The present invention relates to an apparatus for the separation of magnetic constituents from a dispersion comprising these magnetic constituents and nonmagnetic constituents, comprising at least one loop-like canal (5) through which a dispersion flows having at least two inlets (1, 2) and at least two outlets (3, 4), further comprising at least one magnet (6) that is moveable alongside the canal (5), wherein the canal (5) is arranged relative to gravity in a way that nonmagnetic constituents are assisted to go into at least the one first outlet (3) (stream I) by sedimentation and by the current of the dispersion and magnetic constituents are forced into at least one second outlet (4) (stream II) by magnetic force against a current of flushing water. Furthermore, the present invention relates to a process for the separation of magnetic constituents from a dispersion comprising these magnetic constituents and nonmagnetic constituents.
