• Copper Refining Electrolyte and Slime Processing

    Copper electro-refining (Cu-ER) is the principal method for producing >70 of high or 99.97 pure copper cathodes from 97-99 pure blister/fire refined-scrap copper anodes. While the inert and most of less soluble impurities settle as anode slime/sludge other soluble impurities particularly the metalloids (group VA/15 elements or Q As Sb and Bi) and some transition metals (Mt) co-dissolved

    2020-10-13 · Copper electrorefining occurs after the pyrometallurical processing of ores not amenable to acid leaching. The process produces high purity copper either by plating on a re-usable stainless cathode or a copper starter sheet. Copper starter sheets are produced during a 21-hour plating cycle using titanium sheet cathodes which are likewise stripped.
