    Abstract: A process for separating at least one hydrophobic material from a mixture comprising this at least one hydrophobic material and at least one hydrophilic material, which comprises the steps: (A) preparation of a slurry or dispersion of the mixture to be treated in at least one suitable dispersion medium, (B) contacting of the slurry or dispersion from step (A) with at least one solid, hydrophobic surface to bind the at least one hydrophobic material to be separated off to this, (C) removal of the at least one solid, hydrophobic surface to which the at least one hydrophobic material is bound from step (B) from the slurry or dispersion in which the at least one hydrophilic material is comprised and (D) separation of the at least one hydrophobic material from the solid, hydrophobic surface.

    Abstract: La invención se relaciona con un método para remover por lo menos una primera sustancia de una mezcla que contiene por lo menos una primera sustancia y por lo menos una segunda sustancia. Tal método comprende las siguientes etapas: (A) poner en contacto la mezcla que contiene por lo menos una primera sustancia y por lo menos una segunda sustancia con por lo menos una sustancia de superficie activa, opcionalmente en presencia de por lo menos un dispersante, la sustancia de superficie activa que se une a por lo menos una primera sustancia, (B) opcionalmente agregar por lo menos un dispersante a la mezcla obtenida en la etapa (A) para obtener una dispersión, (C) tratar la dispersión obtenida en la etapa (A) o (B) con por lo menos una partícula magnética hidrofóbica de manera que por lo menos una primera sustancia a la cual por lo menos una sustancia de superficie activa se une, y por lo menos una partícula magnética se agregan a la misma, (ID) remover el producto de adición obtenido en la etapa (C) a partir de la mezcla aplicando un campo magnético, (E) desintegrando el producto de adición removido obtenido en la etapa (D) para obtener por lo menos una primera sustancia, y por lo menos una partícula magnética como entidades separadas.

    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.
