Abstract:
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.
