Separation of gold particles generated by engraving from water comprises feeding it over beam-shaped barrier so that particles of greater specific weight settle out in front of barrier and are periodically separated off
Separation of gold particles generated by engraving from water comprises feeding it over beam-shaped barrier so that particles of greater specific weight settle out in front of barrier and are periodically separated off
Separation of physically detectable particles (3) from a current of carrier liquid comprises feeding it over a beam-shaped barrier (6) so that the particles (3) of greater specific weight settle out in front of the barrier. They are then periodically separated off, separation being controlled by a signal generated by a detector for the particles. An Independent claim is included for an apparatus for carrying out the above process containing detectors which generate signals fed via a control to a servo system which controls an outlet.
