我国金矿资源概况及选冶技术研究进展

General Situation of Gold Resources and Research Progress of Mineral Processing and Hydrometallurgy Technology in China

我国金矿资源主要集中在山东、甘肃、新疆、内蒙古、河南和云南等6省区,主要为砂金、岩金和伴生金3种类型。我国金矿资源丰富,是世界上最大的黄金生产国、消费国和进口国,但对外依存度较高,金消费大量依赖进口。加强国内金矿资源选冶技术攻关,实现其高效、合理开发,是保障金矿资源安全的重要举措。本文介绍了国内外金矿资源分布及概况,综述了金矿选矿工艺及选矿药剂研究现状、难处理金矿预处理工艺研究现状及湿法浸出工艺研究现状,阐述了金矿选冶技术的显著特点,以及其优点和局限性,展望了无氰浸出工艺和绿色高效的无氰浸出药剂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借鉴。

Gold resources in China are mainly concentrated in Shandong,Gansu,Xinjiang,Inner Mongolia,Henan and Yunnan Provinces,which are mainly composed of placer gold,rock gold and associated gold.China has rich gold resources and is the largest gold producing,consuming and importing country in the world,but it has a high degree of foreign dependence and a large amount of gold consumption depends on imports.It is an important measure to ensure the safety of gold resources to strengthen the research of domestic gold mining technology and realize its efficient and rational development.This paper introduces the distribution and general situation of gold ore resources in China and abroad,summarizes the research status of gold ore beneficiation technology and beneficiation reagents,pretreatment technology of refractory gold ore and wet leaching technology,expounds the salient characteristics of gold ore beneficiation technology,as well as its advantages and limitations.It is expected that cyanide-free leaching process and green and efficient cyanide-free leaching agents will be the development direction of green gold extraction from refractory gold ores,which will provide reference for further research and application of gold extraction technology.
