    Abstract: The invention relates to a method for separating at least one first substance from a mixture containing said at least one first substance and at least one second substance. Said method consists of the following steps: (A) the mixture containing the at least one first substance and at least one second substance is brought into contact with at least one selective hydrophobing agent in the presence of a suspension agent such that an adduct is formed form at least one hydrophobing agent and the at least one first substance, and not from the at least one second substance; (B) the adduct from step (A) is brought into contact with at least one magnetic particle which is functionalised on the surface with at least one polymer compound having a transition temperature LCST (Lower Critical Solution Temperature), at a temperature at which the polymer compound has a hydrophobic character, such that the adduct from step (A) and the at least one functionalised magnetic particle agglomerates; (C) another suspending agent is optionally added to the mixture obtained in step (B); (D) the agglomerate present in the suspension in steps (B) or (C) is separated by applying a magnetic field; (E) the agglomerate separated in step (D) is divided by controlling a temperature at which the polymer compound has a hydrophilic character, in order to obtain at least one first substance.

    Abstract: 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.

    Abstract: The invention relates to a method for separating at least one first material from a mixture containing said at least one first material and at least one second material. Said method comprises the following steps: (A) a suspension of the mixture containing at least one first material and at least one second material and at least one magnetic particle is produced in a suitable suspending agent; (B) the pH of the suspension obtained in step (A) is adjusted to a value at which the at least one first material and the at least one magnetic particle have opposite surface charges such that the same agglomerate; (C) the agglomerate obtained in step (B) is separated by applying a magnetic field; and (D) the agglomerate separated in step (C) is split by adjusting the pH to a value at which the at least one first material and the at least one magnetic particle have identical surface charges in order to obtain the at least one first material.
