  • 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).

  • Copper Refining

    In the electrolytic process, copper is electrodeposed to obtain a spongy powder deposit at the cathode rather than a smooth, adherent one. In this feature, it differs from the process of copper refining where a strongly adherent product is desired. Low copper ion concentration and high acid content in the electrolyte favor formation of powder deposits.

  • The Extraction of Copper

     · Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated before refining (e.g., via froth flotation).
