    Abstract: 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).

    Abstract: In a method for separating magnetisable particles from a suspension, the suspension is passed through a cylinder-symmetrical separator wherein the substance streams are separated by means of at least one tubular separation screen. According to the invention, the separator separates the substance stream into a concentrate as well as a so-called tailing and the control of the separation rate of the concentrate and tailing is carried out solely by controlling the flow rate. To this end, at least one separation screen (11, 21) is displaceable in the separator (10, 20), so that a variable gap (15, 25) is formed.
