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.

The invention relates to a method and current measuring arrangement for measuring electric current flowing in an individual electrode in an electrolysis system. The electrolysis system comprises a plurality of interleaved electrodes (1, 2), cathodes (1) and anodes (2), arranged in an electrolysis cell (3) and immersed in electrolyte, said electrolysis system having a busbar (4) disposed on a separating cell wall (5) between each of the two adjacent cells to conduct electric current to the electrodes via a contact point (6) between the busbar and a hanger bar (7) of the electrode, and the current sensing arrangement comprises a magnetic field sensing means (8; 8 1 , 8 2 ; 10) for measuring the magnetic field induced by said current. The magnetic field sensing means (8; 8 1 , 8 2 ; 10) are arranged to sense the magnetic field substantially at the level of the contact point (6).

According to an aspect of the invention, the invention is a system for electro¬ lytic processing or recovery of a metal from an electrolyte solution (233). The system comprises electrolysis cells (210,220) and a rectifier (240). The cells comprise interleaved anodes (216) and cathodes (214).The anodes or the cathodes of a first cell have an elec¬ trical connection to a positive (204) or a negative terminal (202) of the recti¬ fier (240), respectively, via a first electrical path having a first re¬ sistance (215).The anodes or the cath¬ odes of a second cell have an electrical connection to a positive or a negative terminal of the rectifier, respectively, via a second electrical path having a second resistance (225). The second re¬ sistance is configured to be higher than the first resistance. The system further comprises a channel (232) for electro¬ lyte from the first cell to the second cell, the electrolyte containing the metal in a dissolved ionic form, metal concentration in the first cell being higher than in the second cell.
