摘要
云南某金矿提金后的氰化尾矿堆存量日益增大,对安全环保等带来不良影响。同时尾矿中含有Au、Ag、Cu、Pb、Fe等有价金属,采用磁化焙烧工艺对其进行处理,可综合回收有价金属,在消除环境危害的同时增加经济效益。
The stockpiling volume of cyaniding tailings from gold extraction in a gold mine in Yunnan is increasing progessively, which brings harmful effect to safety and environmental protection. At the same time, there are several valuable metals in the tailings, such as Au, Ag, Cu, Pb, Fe and so on, the tailings can be treated by magnetic roasting technology to reclaim valuable metals comprehensively, which can eliminate environmental hazards and increase economic benefit.
