AbstractAddressng the issueof excessvely high oxygencontent inanode plates during thecopper pyro-refining proces，，a systematicanalysisofthkeyfactorsifluencingoxygencontentwasconductedExperimentalresearchaimedatreducingtheoxgen contentinanodeplateswascarriedoutthrough processoptimizationandequipmentimprovements.Theresultsindicatethatby adoptingashalowoxidationprocesscombinedwithsulfur-containingreduction，theoxygenmass fractionattheoxidationendpoint was reduced from 0.40% to a range of 0.33% to 0.38% . Following the introduction of the Leward intelligent judgment system for the oxidation-reductionendpoint，theoxygen mass fractionatthereductionendpointwasconsistentlystabilized below 0.15% ： Furthermore，modfcationstosealthelaunderefectivelyminimizedscondaryoxidationduringthecastingprocess.Throughthese comprehensivemeasures，theaverageoxygen massfraction inanode plates producedbytheNo.1anode furnacedecreased from 0.159 0% to 0.0950%，andfortheNo.2anode furnace，itdecreasedfrom 0.1835% toO.O96O%.This studysignificantlyreduces the dissolutionrateofcopperanodesduringelectrolysis，rovidingatheoreticalbasisandpracticalguidanceforimprovingthequalityof electrolytic copper.
