A filter press device for electrolytic production of metal for electrodeposition of metal from solutions, constructed from a plurality of cells connected electrically and hydraulically in series. Each has alternating frames and ion-exchange membranes to form alternating anode and cathode compartments, allowing the free path of liquid. Anolyte or catholyte passes through each compartment. The electrolyzed product is discharged from the compartment in the form of metal or a metallic compound. The electrodes are designed with a vertical base plate acting as an anode with the respective anolyte in a cell unit and in the other, acting as a cathode with the respective catholyte in the adjacent cell unit. Completed the production cycle, the device is stopped, the cell is opened, allowing the metal deposition electrodes, cathodes, can be removed and replaced to start a new productive cycle or remain in place with automatic detachment of metal product.

Filter press device for electrodeposition of metal from solutions, which is made up of separating elements conformed by ion exchange membranes forming a plurality of anolyte and catholyte chambers, wherein the electrodes are connected in series with automatic detachment of the metal product

The invention is directed to a process for extracting a metal from a slag containing said metal, wherein the liquefied metal-containing slag is heated in at least one electric arc furnace (). In order provide an improved method for recovering especially copper from slags, the invention provides that the metal-containing slag is heated in a first furnace () constructed as an AC electric furnace or a DC electric furnace, and the melt is introduced from the first furnace () into a second furnace () which is constructed as a DC electric furnace. Further, the invention is directed to an arrangement for extracting a metal from a slag containing said metal.
