Abstract: Method for separating first type particles from a mixture of at least first type particles and second type particles, the method comprising contacting in a dispersion medium first type particles and second type particles with magnet type particles, so that in the dispersion medium first type particles agglomerate to magnet type particles to obtain magnetic agglomerates, separating magnetic agglomerates from second type particles by applying a magnetic field; wherein during step an amount of energy is transferred into a mixture of the dispersion medium, first type particles, second type particles and magnet type particles.
