ABSTRACT:
In a process for separating relatively magnetic mineral particles P.sub.m having magnetic susceptibilities .chi..sub.m, with .chi..sub.m >0 from relatively non-magnetic particles P.sub.n, having magnetic susceptibilities .chi..sub.n, with .chi..sub.m >.chi..sub.n, all the particles are suspended in a liquid stream, which is supplied to a separating container. The container is provided with an inlet and an outlet and forms a passageway for the stream therebetween. Furthermore an arrangement of magnetizable matrix elements provided in the passageway is magnetized. The supplying and magnetizing are conditioned in such a way, that depositions of particles are obtained predominantly upon the downstream side of the elements. From all the particles magnetic particles P.sub.m are captured to an effective amount upon the downstream side, thereby resulting in a high grade deposition.
