<p>1. Process for working up metal parts provided with a surface coating, wherein the metal parts to be worked up are comminuted to a particle size of from 1 to 20 millimetres, these coarse fractions are subjected to fine comminution in micro-vortex mills whereby the coarse fractions are comminuted to a particle size of about 300 mu m (micrometres), the mixture of solids consisting of a metal fraction and a non-metal fraction is then separated in sifters into the metal fraction and the non-metal fraction, the non-metal fraction is agglomerated and the metal fraction passed on to further processing.</p> |
