Method for refining or concentrating minerals, characterized in that a mineral associated with a gangue having a hydrophobic surface and being in particulate form, is brought into contact with particles of a magnetic material also having a hydrophobic surface, such so that the mineral particles attach to the surface of the magnetic particles, the magnetic particles with the attached mineral particles are separated from the gangue by magnetic means, and the mineral particles are then detached from the magnetic particles. |
