| 摘 要： | 对某含砷、含碳金精矿进行常规氰化浸出,金浸出率仅为40.82%。采用焙烧预氧化—氰化提金工艺进行处理,取得了较好的技术指标:砷、硫、碳脱除率分别为71.23%、96.60%、87.63%,金氰化浸出率达到91.40%。这为有效利用含砷、含碳双重难处理金矿资源提供了技术依据。 |

| Abstract: | Experimental study on extraction of gold from refractory gold concentrates containing arsenie and ear- bon by roasting-cyanide leaching process was performed. Conventional cyanide leaching towards arsenic and carbon contained gold concentrates simply obtains a gold leaching rate of 40.82 %. A roasting-cyanide leaching process was used and reached a rewarding result. At optimum conditions, the technic indexes obtained are as follows： arsenic re- moval rate is 71.23 %, desulphurization rate is 96.60 % and carbon removal rate is 87.63 %, and leaching rate of gold is 91.40 %. This provides technical foundations for the treatment of refractory gold resources with double obsta- cles. |
