    • The present invention relates to a process for separating at least one first material from a mixture comprising this at least one first material and at least one second material, which comprises at least the following steps: (A) contacting of the mixture comprising at least one first material and at least one second material with at least one surface-active substance, if appropriate in the presence of at least one dispersion medium, with the surface-active substance binding to the at least one first material, (B) if appropriate, addition of at least one dispersion medium to the mixture obtained in step (A) in order to obtain a dispersion, (C) treatment of the dispersion from step (A) or (B) with at least one hydrophobic magnetic particle so that the at least one first material to which the at least one surface-active substance is bound and the at least one magnetic particle agglomerate, (D) separation of the agglomerate from step (C) from the mixture by application of a magnetic field in order to obtain the agglomerate and a mixture M1 depleted in agglomerate, and repetition of the steps (A) to (D).
    • 本发明涉及从包含至少一种第一材料和至少一种第二材料的混合物中分离出至少一种第一材料的方法,该至少一种第二材料至少包括以下步骤:(A)将包含至少一种 第一材料和至少一种具有至少一种表面活性物质的第二材料,如果合适,在至少一种分散介质的存在下,表面活性物质与至少一种第一材料结合,(B)如果合适, 向步骤(A)中获得的混合物中加入至少一种分散介质以获得分散体,(C)用至少一种疏水磁性颗粒处理来自步骤(A)或(B)的分散体,使得 所述至少一种表面活性物质与所述至少一种表面活性物质结合的至少一种第一材料和所述至少一种磁性颗粒附聚物,(D)通过施加磁场从所述混合物中分离所述附聚物与步骤(C) 以获得附聚物和耗尽附聚物的混合物M1,以及重复步骤(A)至(D)。
