Abstract (en)

[origin: WO2009030669A2] The invention relates to a method for removing at least one first substance from a mixture that contains the at least one first substance and at least one second substance. Said method comprises the following steps: (A) contacting the mixture containing at least one first substance and at least one second substance with at least one surface-active substance, optionally in the presence of at least one dispersant, the surface-active substance binding to the at least one first substance, (B) optionally adding at least one dispersant to the mixture obtained in step (A) to obtain a dispersion, (C) treating the dispersion obtained in step (A) or (B) with at least one hydrophobic magnetic particle so that the at least one first substance to which the at least one surface-active substance is bound and the at least one magnetic particle are added thereto, (D) removing the addition product obtained in step (C) from the mixture by applying a magnetic field, (E) breaking down the removed addition product obtained in step (D) to obtain the at least one first substance and the at least one magnetic particle as separate entities.
