    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.
