    Abstract: The present invention relates to a process for concentrating desired particles comprising a carrier-magnetic-separation comprising the following steps a) providing a feedstock which contains the desired particles and an undesired material;b) adding hydrophobic magnetic particles to the feedstock which results in a loaded feedstock containing agglomerates of the magnetic particles and the desired particles or of the magnetic particles and the undesired material; c) separating the agglomerates from the loaded feedstock by a separation method which results in isolated agglomerates, where the separation method is selected from sorting, electric separation, magnetic separation, screening, classification, gravity concentration,and flotation;d) breaking up the isolated agglomerates to obtain a suspension comprising the magnetic particles in desagglomerated form; and e) separating the magnetic particles from the suspension obtained in step d) by a separation method selected from sorting, electric separation, magnetic separation, screening, classification, gravity concentration, and flotation.
