    Abstract: The present invention relates to a method for separating at least one first substance from a mixture containing said at least one first substance in an amount of 0.001 to 1.0 wt %, based on the total mixture, and at least one second substance, comprising at least the following steps: (A) bringing the mixture into contact, (B) optionally adding at least one dispersant, (C) treating the dispersion with at least one hydrophobic magnetic particle, (D) separating the enrichment product from step (C) from the mixture by applying a magnetic field, (E) optionally splitting the separated enrichment product from step (D).

    Abstract: The invention relates to a method for separating at least one material from a mixture comprising said at least one material, at least one second material and at least one third material, comprising at least the following steps: (A) bringing the mixture, comprising at least one first material, at least one second material and at least one third material, into contact with at least one hydrocarbon in a volume of 0.01 to 0.4 wt %, relative to the sum of the mixture and at least one hydrocarbon, in the presence of at least one dispersion agent as applicable;(B) adding of least one dispersion agent to the mixture obtained in step (A) as applicable in order to obtain a dispersion; (C) treating the dispersion from step (A) or (B) with at least one hydrophobic magnetic particle such that the at least one first material and the at least one magnetic particle accumulate (D) separating the accumulation product from step (C) from the mixture by creating a magnetic field; (E) splitting the separated accumulation product from step (D) as applicable in order to obtain the at least one first material and the at least one magnetic particle separately.
