A method of separating a mixture of particles in a liquid that within chosen limits have different physical property values, wherein the particles to be separated are supplied via a feeder to a screen upon which a layer of facilitating particles is disposed the size of the facilitating parties being too large to fit through the openings in the screen, wherein particles to be separated are passed through the layer of facilitating particles and through the openings in the screen and collected under the screen, the density of the particles being greater than that of the liquid, and wherein a repetitive vertical movement is provided between the particles and the liquid, respectively.
