  • Electrowinning Copper Chemistry Tutorial

    Electrowinning refers to the process of using electrolysis to extract a metallic element from the compounds in its ore. Copper occurs on Earth both as native copper (the uncombined element, Cu), and in ores (copper compounds, or mixtures of compounds, from which copper metal can

  • Electrorefining of Metals,electrorefining of Copper

    The process of electrorefining of metals involves the following steps: The electrolyte is usually an aqueous solution of the salt of the metal with some corresponding acid, if necessary. A thick block of impure metal is made the anode. A thin rod/sheet of pure metal is made the cathode.

    In copper processing: Electrorefining. This is the final step in both pyro and hydrometallurgical processing. In the electrolytic process, copper anodes and starting sheets are immersed in an electrolytic solution made up of copper sulfate and sulfuric acid. An electric current is passed through the solution, and copper Read More nickel

    An example where copper is further purified is at the Asarco electrolytic plant in Amarillo, Texas. The 99% pure copper from the anode furnace is cast into 750pound, 3inch thick, rectangular slabs called anodes. The final step is a process called electrorefining.

    At this current density, the refining process is relatively slow, requiring about 28 days to refine a crude anode weighing about 650 lb. The maximum current density (refining rate) is essentially limited by the rate at which copper ions are transported through the electrolyte from the anode to the cathode.
