河南栾川某尾矿库回采综合回收白钨矿试验研究与生产实践

Experimental Study and Production Practice of Comprehensive Recovery of Scheelite Ore from a Tailings Reservoir in Luanchuan Henan Province

随着矿业经济的快速发展,矿产资源不足的矛盾日益加剧,积极开发尾矿回采技术,对实现资源节约、改善生存环境、提高效益以及资源优化配置和可持续发展都具有重要的意义。河南栾川某尾矿库在原矿WO_3品位为0. 116%左右的情况下,经过粗选、精选可获得品位在31. 37%左右的白钨精矿,整体回收率在82. 32%左右,实现了资源的综合回收。

With the rapid development of mining economy, the shortage of mineral resources is becoming more and more serious. It is of great significance for realizing the resource saving, improving the living environment, improving the efficiency, optimizing the allocation of resources and sustainable development to develop tailings mining technology actively. A tailings reservoir in Luanchuan, Henan Province, under the condition of 0. 116% grade of WO3, through roughing up, can obtain scheelite concentrate with grade of 31.37% or so, and the overall recovery rate is about 82. 32%. The comprehensive utilization of resources, economy, society and resources is achieved.
