摘要
青海省地域辽阔,矿产资源丰富。近10年来,金矿地质找矿取得重大突破,在东昆仑等区域发现青海省的"金腰带",促进了青海省黄金产业的发展。为了进一步实现青海省金矿资源的高效、综合开发利用,对青海省黄金行业矿产资源信息和各黄金生产企业状况进行了收集、整理,并查阅了大量文献资料,对青海省岩金矿产资源的分布、特点、金资源量、已开发的岩金矿石类型、选冶工艺、生产指标和研发平台等有了系统了解。重点介绍了青海省难处理金矿浮选、浮选尾矿环保提金、金精矿生物预氧化和中温中压预氧化的最新研究成果。指出了青海省岩金矿开发研究和产业发展的方向,即加强工艺矿物学研究、选矿厂流程考察诊断和绿色矿山建设,从而实现矿产资源的综合、高效、循环、节约利用以及矿业开发与生态文明建设协调发展。
Qinghai Province has a vast territory and rich mineral resources.Great breakthroughs have been made in gold mine geological prospecting over the last decade.The“gold belt”of Qinghai Province has been found in east Kunlun and other areas,which has promoted the development of the gold industry in Qinghai Province.In order to further implement the comprehensive,efficient,circular and economical utilization of mineral resources in Qinghai Province,collected and sorted out information of the gold industry mineral resources and the production status of major gold enterprises,also consulted a large number of literature materials,so that understand the distribution,characteristics,amount of gold resources,types of developed rock gold mines,flotation-metallurgical process,production index and research and development platform of rock gold mineral resources in Qinghai Province.This paper mainly introduce the latest research results of the refractory gold mines flotation,flotation tailings environmental gold extraction,biological pre-oxidation and medium temperature medium voltage pre-oxidation of gold concentrate in Qinghai Province.At the same time,the direction of the development of research and industry development was proposed,that is strengthen the study of technological mineralogy,the process investigation and diagnosis of concentration plant,the construction of green mines and so achieve comprehensive,efficient,circular and economical utilization of mineral resources,as well as coordinated development of mining development and ecological civilization.
