摘　　要：针对黄金冶炼过程中存在的问题,采用化学法黄金精炼工艺代替原火法冶炼工艺。改造后,金锭纯度由88%提高至99.99%,冶炼回收率提高了0.95%,每年可额外回收银250 kg,取得了良好的经济效益。In view of the problems existing in the gold smelting process, gold refining with chemical process is adopted to replace the original pyrometallurgy process. After the modification, the purity of gold ingot is increased from 88% to 99.99% , the recovery in smelting increases by 0.95% and additional 250 kg silver can be recovered every year with good economic benefits.
