    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 present invention relates to a method for separating at least one hydrophobic agent from a mixture comprising said at least one hydrophobic agent and at least one hydrophilic agent, comprising the steps of: A) Producing a slurry or dispersion of the mixture to be treated in at least one suitable dispersion agent, B) bringing the slurry or dispersion of step (A) into contact with at least one solid, hydrophobic surface for attaching the at least one hydrophobic agent to be separated to the surface thereof, C) removing the at least one solid, hydrophobic surface, whereon the at least one hydrophobic agent from step (B) is bonded, from the slurry or dispersion, in which the at least one hydrophilic agent is present, and D) separating the at least one hydrophobic agent from the solid, hydrophobic surface. According to the invention, the method is used for separating (hydrophobic) sulfidic minerals, particularly copper sulfides, from mixtures having hydrophilic metal oxides (gang minerals). The solid surface can be, for example, a conveyor belt having a hydrophobic, structured surface.
