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 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.

Abstract: The invention relates to a method for producing modified ZnO particles in which a zinc salt and a base are mixed in a polar solvent and the polar solvent is optionally removed after precipitation of a precipitation product, resulting in a residue, wherein the residue is absorbed in a non-polar solvent, surface active substances are added, other active substances are optionally added and then the modified ZnO particles are separated from other byproducts. The invention also relates to materials such as plastics, varnishes or paints containing modified ZnO particles. The invention also relates to a method for incorporating modified ZnO particles into materials, wherein the modified ZnO particles are incorporated into the materials in the form of dispersions or suspensions, and to the use of modified ZnO particles for protecting materials against the effects of light, heat, oxygen or radicals, as catalysts, for semiconducting layers or for cosmetic uses.
