摘　　要：为解决某尾矿堆存和对环境潜在的污染问题,对该低品位尾矿进行了资源化处置与综合利用技术研究。根据尾矿工艺矿物学研究结果,进行了可利用有价元素及有用矿物综合回收研究、尾矿深度除杂试验研究、多功能矿物硅肥的制备技术研究。确定了适合该尾矿性质的"浮磁重梯次回收有用矿物-尾矿制硅肥"的工艺技术路线,在回收利用有价元素基础上,使难利用的尾矿资源变成了铜精矿、硫钴精矿、铁精矿、云母精矿与硅肥产品,实现了尾矿资源化及减量化。In order to solve the problems of tailings storage and potential pollution to the environment in a resource-intensive mining area,the technology of resource treatment and comprehensive utilization of the low-grade tailings was studied.According to the research results of mineralogy of tailings process,the research of comprehensive recovery of valuable elements and useful minerals,deep impurity removal test of tailings,and preparation technology of multifunctional mineral silicon fertilizer were carried out.The technical process of "floating magnetic gravity cascade recovery of useful mineral--silicon fertilizer from tailings" suitable for the tailing property is determined.On the basis of the recovery and utilization of valuable elements,the hard-to-use tailing resources are transformed into copper concentrate,sulfur cobalt concentrate,iron concentrate,mica concentrate and silicon fertilizer products,thus realizing the resource recovery and reduction of tailing.
