the electrosis stage of copper processing

  • Electrolysis

    In chemistry and manufacturing, electrolysis is a technique that uses a direct electric current (DC) to drive an otherwise non spontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell.

  • copper extraction and purification

    The purification uses an electrolyte of copper(II) sulphate solution, impure copper anodes, and strips of high purity copper for the cathodes. The diagram shows a very simplified view of a cell. At the cathode, copper(II) ions are deposited as copper. At the anode, copper goes into solution as copper(II) ions.
