• US5783057AMethod of purifying copper electrolytic

    A method of purifying a copper electrolytic solution circulated in a copper electrorefining system wherein a portion of the solution is withdrawn and recycled to the system after purification treatment. The purification treatment includes the addition of a hydrosulfide to the withdrawn solution to generate only the necessary quantity of hydrogen sulfide gas required in the reaction.
