| 中文摘要: |
| 随着优质金矿不断被开发消耗，难处理金矿占比不断地提高，从难处理金矿中回收金是金产业未来发展的必然趋势。本文简要分析了难处理金矿浸出困难的原因，介绍了焙烧氧化法、热压氧化法、生物氧化法、机械活化法、微波法5种预处理技术和氰化法、硫脲法、硫代硫酸盐法、卤素法、火法5种金回收技术的研究进展，并比较了5种预处理技术和4种湿法金回收技术的优势与不足。在此基础上对难处理金矿预处理和金回收技术的前景进行了展望。 |
| 英文摘要: |
| With the continuous exploitation and consumption of high-quality gold ores, the proportion of refractory gold ores is increasing. Recovering gold from refractory gold ores is the inevitable trend of the future development of gold industry. The causes of difficult leaching of refractory gold ores are briefly analyzed in this review，and the research progress of five pretreatment technologies including roasting oxidation, hot pressing oxidation, biological oxidation, mechanical activation and microwave, as well as five gold recovery technologies including cyanidation, thiourea, thiosulfate, halogen and pyrometallurgical are also introduced. The advantages and disadvantages of five pretreatment technologies and four wet-process gold recovery technologies are compared. Finally, future developments in the pretreatment methods and the recovery technology of refractory gold ores are prospected. |
