摘　　要：为解决攀西地区某典型尾矿资源化利用问题,对该低品位尾矿进行了综合回收利用研究。基于尾矿工艺矿物学研究结果,研发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产率11.78%、K_(2)O品位7.77%、回收率25.92%的云母精矿和有效硅含量40%以上的硅肥产品,尾矿减少64.66%,实现了尾矿资源化及减量化。In order to solve the problems of typical tailings resource utilization from Panxi region,the technology of comprehensive utilization of the low-grade tailings was studied.Based on the research results of mineralogy of tailings process,the technical route of"floating-magnetic-gravity echelon 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 mica concentrate withyield of 11.78%、K_(2)O grade 7.77%、recovery rate of 25.92%and silicon fertilizer products with effective silicon more than 40%.The tailings can be reduced by 64.66%,thus realizing the resource recovery and reduction of tailing.
