ABSTRACT:
A method for dividing a heterogeneous collection of ore particles prior to concentration thereof into groups differing in size and density of the particles by passing the particles in dispersion in a liquid through a space having obstacles therein which are arranged such that the sizes of the openings between the obstacles are always larger in size than the major number of particles arriving at the openings while simultaneously agitating the medium. This results in a variation of the path of the particles depending on their size and density and allows only the smaller and/or heavier particles to be brought to the concentration.
