摘要
介绍了用空气氧化预浸加石灰焙烧焙砂中的ＣａＳ，以消除其对金氰化的影响。预浸后金的氰化浸出率可从５８％提高到８０％以上。
It was reported in this paper that CaS in the calcined ore of refractary gold ore roasted with the addition of lime was eliminated by oxidation with air. After the pretreatment of oxidation ,the cynide leaching rate of gold increased to over 80%.
