A method of separation and sorting of the insulation-cover from the metal core of various electric wires and cables, comprising an agitation-tank providing an impact agitating force to small cut pieces of various insulated electric wires and/or cables in the middle of the tank which is filled with a liquid, at room temperature or properly heated, and a bath filled with a particular liquid which is lighter in its specific gravity than the metal core, but heavier than the insulation-cover, enabling perfect sorting of the insulation-cover from the metal core in the middle of the bath.
