摘要
某含砷、锑金精矿直接氰化金浸出率仅42.79%,采用常规焙烧—氰化工艺金浸出率仅48.22%,而采用碱浸—两段焙烧—磨矿—氰化工艺金浸出率达到了86.3%。同时锑脱除率达到了96.6%,也可作为产品外售。
The gold extraction recovery from refractory gold concentrate with As and Sb content using cyanide leaching process is only 42.79%,and it can be raised to 48.22% using roasting-cyandiation process.The gold recovery can be improved further to 86.3% by antimony removing with sodium sulfide,followed by roasting,milling and cyanide leaching process,while antimony removal rate reached to 96.6%,antimony can be sold as by-product.
