Procedure to separate the Metal AG, au, PT, PD, RH, RU, ir, os, Cu, MO, ni, MN, Zn, Pb, Hg, CR, SN, V, and mixtures thereof, which comprises a slag from the slag, grinding, contact with at least a Magnetic Particle agglomerates and separating the mixture through implementation of a ca MPO Magnetic; and using at least a Magnetic Particle.

摘要

The present invention relates to a process for the separation of at least one metal from a slag, comprising that at least one metal and further components, comprising at least step (A) grinding the slag, (B) if appropriate, contacting the ground slag of step (A) with at least one surface-active substance and/or at least one magnetic particle, if appropriate in the presence of at least one dispersant, resulting in formation of agglomerates of the at least one metal and the at least one magnetic particle, (C) if appropriate, addition of at least one dispersant to the mixture obtained in step (B) to give a dispersion having a suitable concentration, and (D) separation of the agglomerates from the mixture of step (B) or (C) by application of a magnetic field, and to the use of at least one magnetic particle for the separation of slag.
