METHOD FOR COPPER OBTAINING FROM SCRAP OF COPPER CURRENT CONDUCTORS

A method for copper obtaining from scrap of copper current conductors involves processing of copper conductors scrap into the fibers, their compression in the press mold, heating of the obtained briquettes in the protective-reducing medium, pressing in the closed punch, repeated heating of the extru...

description A method for copper obtaining from scrap of copper current conductors involves processing of copper conductors scrap into the fibers, their compression in the press mold, heating of the obtained briquettes in the protective-reducing medium, pressing in the closed punch, repeated heating of the extruded billet, stick extrusion and its annealing in the vacuum. The fibers are briquetted to the compactness. Briquettes are heated, pressed with cross deformation. The obtained billets are treated with the pressure in the cold form and annealed in the protective-reducing medium.
