龙山金锑矿低品位老窿残矿回收技术

Technology for Recovery of Longshan Gold Antimony Mine′s Low Grade Remnant Orebody with Remained Old Workings

在分析研究龙山金锑矿低品位老窿残矿特征的基础上,结合矿山生产实际,采用脉外平巷加穿脉群回采方案和部分优先—混合浮选工艺,综合回收低品位老窿残矿,经过1年多的生产实践证明,该项技术金锑回收率高、回采作业安全性好、经济效益显著,可为类似矿山提供借鉴。

Based on the analysis of the characteristics of low grade remnant orebody with remained old workings in Longshan gold-stibium mine. In consideration of using existing conditions of operation, stopping scheme with fringe drift heading and roadway across the vein and preferential fraction-mix flotation process on complex recovery of low grade remnant orebody with remained old workings are introduced. This technology offers high recoveries of gold and stibium and excellent stopping safety performance and obvious economic benefit through the demonstration of one years practice, which can be taken by similar mines for reference.
