processing of copper rods from scrap using electro refining

Smelting is a type of refining process for extracting pure form of copper from its ore. It uses heat and chemical reducing agent for decomposition of copper ore, elimination of unwanted slag, and other elements for obtaining pure copper cathode. Electro-refining is a process, wherein copper ore is carried out in the presence of using aqueous

    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

    Black copper is the product of low grade copper scrap or WEEE/PCB by simple smelting. The composition of black copper is very complicated and impurities has to be removed by fire-refining in order to get copper anode possible for further processing by electro-refining to produce standard copper cathode and byproduct anode slime

    Electrorefining of Copper

    Electrorefining processes using a molten salt or non-aqueous electrolyte are used and, indeed, are the subject of further development. This is due to the possibilities they offer for increasing current densities and refining via lower oxidation states not stable in water (e.g. refining of copper via Cu+ would almost halve the energy requirement)
