| 中文摘要: |
| 针对低品位微细粒金矿中金的赋存特点，对其浮选精矿进行高压氧化-氰化浸出工艺处理。重点考察了高压氧化预处理过程中的温度、液固比和氧化时间对预处理效果的影响。预处理渣再磨后氰化浸出，金的浸出率(对浮选精矿)为94.30%，渣率为10.88%。 |
| 英文摘要: |
| Considering the occurrence features of gold in low-grade microgranular gold mine, high- pressure oxidation-cyanide leaching process was used for treating its flotation concentrate. The effects of temperature, liquid-solid ratio and oxidation time, during the process of high-pressure oxidation, on pre- treatment were investigated crucially. The pretreatment slag was ground and leached with sodium cyanide. The leaching rate of gold, for flotation concentrate, was 94.30%, and the residue rate was only 10.88%. |
