Abstract (en)
An electrolytic process and an electrolytic cell for recovering metal values from low grade concentrates. The said concentrate is introduced into the cell containing an aqueous electrolyte so that it is retained in proximity to an anode or anodes (8) and kept out of contact from the or each cathode (9). The cell is energised so that electrolysis takes place and acid is released at the anode(s) (8) which dissolves the metal values which form cations which migrate to and are discharged at the cathode(s) (9). The impurities in the concentrate form fine particles which are separated from the concentrate by screening, e.g. by means of a grid or grids (10) separating the anodes (8) from the cathodes (9).
