摘要
从难处理金矿石中提金是黄金产业发展的必然趋势,而如何绿色、高效地回收金是当前面临的技术难题之一。概述了难处理金矿石的特征,综述了难处理金矿石预处理技术和研究现状,评述了浸金方法的研究进展,并分析了各方法的显著特点和作用机理,以及其优点和局限性,同时展望了预处理技术和浸金方法的合理配置将是难处理金矿石绿色提金的发展方向,为提金技术的进一步研究及应用提供参考依据。
Extracting gold from refractory gold ores is an inevitable trend in the development of the gold industry.However,how to recover gold from refractory gold ores in a green and efficient manner is one of the technical challenges currently.Therefore,the characteristics of refractory gold ores were summarized,the pretreatment technology for refractory gold ores and their current research status were reviewed,the research progress of the leaching processes was evaluated,and the features and reaction mechanisms of each method were analyzed as well as their benefits and limitations.In the meantime,the outlook is that the reasonable allocation of pretreatment technology and leaching method should be the development trend for green gold extraction from refractory ores.The research provides basis for further research and application of gold extraction technology.
