    Abstract: The present 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, comprising at least the following steps: (A) bringing the mixture containing at least one first material and at least one second material into contact with at least one surface-active substance, optionally in the presence of at least one dispersant, wherein the surface-active substance bonds to the at least one first material; (B) optionally adding at least one dispersant to the mixture obtained in step (A) in order to obtain a dispersion; (C) treating 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 bonded, and the at least one magnetic particle attach; (D) separating the attachment product from step (C) from the mixture by applying a magnetic field in order to obtain the attachment product and a mixture M1 depleted of the attachment product, and repeating 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.
