ABSTRACT The present invention relates to a unique and advantageous method making possible a superior technical and economical separation of cemented carbide bodies based upon their com- positions and structures. The critical point of the method is, that after formation of a melt by melting of the binder metal including dis- solved elements from the hard constituents there are so strong driving forces dependent on the grain size vari- ables, proportions and compositions of the hard constituent phases, that melt is re-distributed between cemented car- bide bodies in communicating contact. The re-distribution is determined by differences of mean grain sizes, grain size distributions, relative proportions and compositions of the hard constituent phases of the bodies.
