Abstract
Przedmiotem zgłoszenia jest sposób elektrorafinacji miedzi, w którym elektrorafinację miedzi anodowej prowadzi się w wannie procesowej wypełnionej elektrolitem zawierającym rozpuszczony w wodzie kwas siarkowy, w którym zanurzona jest co najmniej jedna anoda i co najmniej jedna katoda, z okresową zmianą kierunku prądu lub z okresową przerwą w podawaniu prądu, charakteryzujący się tym, że w bezpośredniej bliskości katody, korzystnie w odległości mniejszej od 10 mm od katody, umieszcza się elektrodę, a następnie mierzy się różnicę potencjałów pomiędzy katodą, a elektrodą i steruje się wartością natężenia prądu płynącego w obwodzie wanny do elektrorafinacji miedzi w trakcie impulsu katodowego w taki sposób by wartość różnicy potencjałów między katodą, a elektrodą utrzymywała się na zadanym stałym poziomie.The subject of the application is a method of copper electrorefining, in which anode copper electrorefining is carried out in a process tank filled with electrolyte containing sulfuric acid dissolved in water, in which at least one anode and at least one cathode is immersed, with a periodic change of direction of the current or with a periodic break in feeding current, characterized in that in the immediate vicinity of the cathode, preferably at a distance of less than 10 mm from the cathode, an electrode is placed, and then the potential difference between the cathode and the electrode is measured and the value of current flowing in the circuit of the electro-refining bath is controlled copper during the cathode pulse in such a way that the value of the potential difference between the cathode and the electrode remains constant at a given level.
