  • Electro-refining of copper - Finishing

    22.06.2008· 2002. A. Electrowinning is a fine way to remove copper from phosphoric acid, however, the mixture with nitric acid may make this impractical. If the nitric acid is strong enough, it will redissolve the copper as fast as you are plating it out. If it is weak enough, then electrowinning may work, however, I would not expect to get a dense, good quality plate.

  • Electrowinning - an overview | ScienceDirect Topics

    Electrowinning has proved to be an effective and simple method for recovering gold from the eluate. Electrowinning is done simultaneously with the elution. The barren eluate is recycled to the eluant tank and is recycled for the next elution after the reagents have been made up to their relevant concentrations. Two operating plants, namely Penjom Gold Mine and Barbrook Gold Mine, have now ...
