    Electrode for use in electrometallurgical processes, particularly for use as an anode in copper electrorefining to deposit copper onto starting blanks to make starting sheets or cathode products. The electrode (10) is characterized by having a continuous planar body (11) and extending legs (12). The electrode also preferably has extending arms (13) which are useful as supports when the electrode is immersed in the electrolyte bath. In one configuration each leg (12) is a four sided metal shape having two parallel sides (12a) and (12b) of unequal dimension separated by a generally perpendicular edge and an edge forming an obtuse angle with the shorter of said parallel sides (12a).

    ABOUT
    This invention relates to the design of an anode for electrolytic refining of copper,
    The purpose of the invention is to increase the service life
    The drawing shows the proposed anode.
    The anode contains anode sheet 1 with ears 2 for hanging into an electrolysis bath and protrusions 3 into an quadrilateral with two parallel horizontal sides — short 4 and long 5; Length 5 sides long is up to 25% 10% anode height. The low angle is preferably 116 °, i.e. less than 120, although it may vary widely, for example, more than 135
    The anode works as follows
    A copper sulphate electrolytic bath of composition, g / l: copper 40; chloride 0.030, a titanium auxiliary cathode having edge bands to prevent deposition on the edges is placed in the electrolyzer, and connected to an electrical circuit as a cathode. 41 inches wide (965 tons 1040 mm). Similarly, a black copper bleed anode is immersed in the bath and connected as an anode. The dimensions of the submerged anode are 34.5 inches wide by 39 inches high (876 x 990 mm). In addition, the anode has two legs. OT extending from the bottom and adjacent to each vertical sidewall, 5 each with a height of 2 inches and parallel sides of 4 inches and 5 inches in length (respectively 50, 100 and 125 mm).
    Then, a cad is deposited on the auxiliary cathode at a current density of 24 A / ft (216 A / dm) for 24 hours, the copper is peeled off, and the procedure is repeated for a number of days. Copper is completely and evenly deposited on the surface of the auxiliary cathode. The cathode base is also easily peeled off from the auxiliary cathode.
