Electrowinning cathode use for gold

  • "Gold Recovery for Dummies" Finishing

    Start with 6V dont use a Cu cathode, use gold, this will keep you from having to refine with acids and some other headaches Remember pH and do NOT pour the CN solution down the sink If youre going to pour make sure the CN is totally killed with something like CaO, Baking soda
