中文摘要: 镇沅含砷、锑、碳难处理金精矿直接氰化金浸出率小于10％，采用常规焙烧—焙砂氰化提金工艺金浸出率仅达到73．2％，而采用先行除锑，再焙挠脱除硫、碳、砷的提金工艺方案，金氰化浸出率达到90．4％，同时锑可作为锑精矿外售，经济效益明显。

Abstract:The gold extraction recovery from Zhenyuan arsenic and antimony bearing carbnous concentrate with cyanide leaching process is less than 10%, and it can be raised to 73.2% with roasting-cyandiation process. The gold recovery can be improved further to 90.4% with antimony removal with sodium sulfide, followed by roasting and cyanide leaching process. The antimony concentrates can be sold as by product.
