Cu—Mo separation

摘要

The present invention relates to a process for separating at least one first material from a mixture comprising this at least one first material, at least one second material and at least one third material, which comprises at least the following steps:
(A) contacting of the mixture comprising at least one first material, at least one second material and at least one third material with at least one hydrocarbon in an amount of from 0.01 to 0.4% by weight, based on the sum of mixture and at least one hydrocarbon, in the presence or absence of at least one dispersion medium,(B) if appropriate, addition of at least one dispersion medium to the mixture obtained in step (A) in order to obtain a dispersion,(C) treatment of the dispersion from step (A) or (B) with at least one hydrophobic magnetic particle, so that the at least one first material and the at least one magnetic particle agglomerate,(D) separation of the adduct from step (C) from the mixture by application of a magnetic field,(E) if appropriate, dissociation of the adduct which has been separated off in step (D) in order to obtain the at least one first material and the at least one magnetic particle separately.

1. A process for separating at least one first material from a first mixture comprising the at least one first material, at least one second material, and at least one third material, the process comprising:
(A) contacting the first mixture, comprising at least one first material, at least one second material, and at least one third material, with at least one hydrocarbon in an amount of from 0.012 to 0.4% by weight, based on a sum of the first mixture and the at least one hydrocarbon, to obtain a second mixture; (B) optionally, adding at least one dispersion medium to the second mixture obtained in (A), in order to obtain a dispersion; (C) treating the second mixture from (A) or the dispersion from (B) with at least one hydrophobic magnetic particle, so that the at least one first material and the at least one magnetic particle agglomerate, to obtain an adduct in a third mixture; (D) separating the adduct from (C) from the third mixture by applying a magnetic field; (E) optionally, dissociating the adduct which has been separated off in (D), in order to obtain the at least one first material and the at least one magnetic particle separately.
