    摘要： According to an aspect of the invention, the invention is an electrode assembly for electrolytic processing of a metal in an electrolysis cell. The electrode assembly comprises an electrode blade comprising a metallic hanger bar portion, a first lug for supporting the metallic hanger bar portion on a first power supply bar, an insulating piece connecting the metallic hanger bar portion to the first lug. The electrode assembly also comprises an electrical switch unit controlling electrical current supply between the first lug and the metallic hanger bar based on a control signal transmitted to a terminal of the electrical switch unit. The electrode assembly also comprises a control unit configured to transmit the control signal to the terminal of the electrical switch unit. The electrode assembly has a power storage unit configured to supply power to the control unit, the power storage unit being charged from the first lug and the hanger bar when the electrical switch unit switches off electrical current supply between the first lug and the metallic hanger bar.

    摘要： The present invention provides a method of separating precious metals from anode sludge obtained from copper electrolysis, comprising (a) leaching the anode sludge in an aqueous sulfuric acid solution to remove leachable chlorides and to obtain a first leaching residue depleted of chlorides; (b) pressure leaching the first leaching residue to dissolve Ag and Se and to obtain a first filtrate comprising Ag and Se and a second leaching residue depleted of Ag and Se; and (c) leaching the second leaching residue with an aqueous hydrochloric acid solution to dissolve Au and PGMs to obtain a second filtrate comprising Au and PGMs and a final leaching residue.
