摘　　要：以大量的试验研究和生产实践为依据,分析了不同预处理技术对难选冶金矿石的适应性。通过分析研究,进一步阐述了难选冶金矿石预处理技术的选择依据和方法。针对难选冶金矿石的工艺特性,采取科学合理的预处理提金工艺,可最大限度地提取金并综合回收多种有价元素,从而实现资源的高效利用。Based on a number of experimental research and production practices,the accessibility of various pre- treatment processes towards refractory gold ores is analyzed. According to the analysis, it is further explained why and how the pretreatment process of refractory ores is chosen. In light of the characteristics of the gold ores, proper pretreat- ment processes are adopted, comprehensively extracting many precious elements besides maximizing the recovery of gold. Thus highly efficient utilization of resources is achieved.
