| 摘 要： | 在试验研究基础上,提出了一种提高含砷金精矿二段焙烧-氰化浸出工艺金浸出率方法.试验结果表明,含砷金精矿经一段焙烧(450～500℃)除砷后,加入一定量的添加剂SR,再进行二段焙烧(630～650℃),然后经稀硫酸除铜后进行氰化浸出,可使金的氰化浸出率提高4.65%.该方法可获得较好的经济效益和社会效益. |

| Abstract: | Based on experimental researches,a two-stage roasting and cyanidation technique is proposed to enhance the gold leaching rate of a gold concentrate containing arsenic.After the first stage roasting（450~500 ℃） to remove arsenic,an additive SR is added before the second stage roasting（630~650 ℃）,and then dilute sulphuric acid is used for copper removal,the final process is cyanidation leaching.The test results show that the leaching rate of gold increases 4.65%,and good economic and social benefits are obtained. |
| Keywords: | gold concentrate containing arsenic two-stage roasting cyanidation gold leaching rate |
