摘　　要：以玉龙铜矿含铜尾矿为研究对象,通过实地调查取样、尾矿毒性鉴别、以及尾矿堆场土壤和水样的测试,证明该尾矿为第一类工业固体废物,可以直接堆存或填埋。采用物相分析证明尾矿中仍含有大量氧化铜矿物,使用硫酸浸取工艺可回收该尾矿中80%的铜,实现了环境保护和资源利用的"双赢"目的。This paper takes Tailings with copper from Yulong copper Mine as the object of study.Through field investigation and sampling,tailings＇ toxicity indentification and tests of soil and water from tailings storage yard,the results was proved that the tailings belong to the first class of industrial solid waste,which can be directly stacked or landfilled.Phase analysis was employed to prove that a lot of copper oxide minerals existed in the tailings.80% of copper in the tailings could be recyled by adopting the sulfuric acid leaching process,realizing the ＂Win-Win＂purpose of environmental protection and resource utilization.
