摘要
为了回收利用攀西某选厂强磁选尾矿中的TiO2,在矿样性质研究的基础上,开展了尾矿再选钛工艺试验研究.试验结果表明:矿样经粗细分级—细粒级1粗1精1扫强磁选预富集,获得了TiO2品位19.02%、TiO2回收率41.46%的预富集精矿;针对预富集精矿,通过浮选闭路试验,最终获得了产率31.74%、TiO2品位47.14%、TiO2回收率79.11%的钛精矿,全流程钛综合回收率为32.80%;研究成果可为该选厂强磁尾矿再选钛提供技术支撑,对其他强磁尾矿资源的再选具有借鉴意义.
Abstract
In order to recycle and reuse TiO2 from the tailings of high intensity magnetic separation in a concentrator in Westem Panzhihua,based on the study of the properties of ore samples,the experimental study on the process of titanium re-separation from tailings is carried out.The results show that the pre-en-riched concentrate with TiO2 grade of 19.02%and TiO2 recovery of 41.46%is obtained by pre-concentrating the ore sample by coarse and fine classification-fine grained one roughing one cleaning one scavenging high intensity magnetic separation.For the pre-enriched concentrate,titanium concentrate with yield of 31.74%,TiO2 grade of 47.14%,and TiO2 recovery rate of 79.11%is finally obtained through flotation closed-circuit test.The comprehensive recovery rate of titanium in the whole process is 32.80%.The research results can pro-vide technical support for the re-separation of titanium from high intensity magnetic tailings in the concentra-tor,and have reference significance for the re-separation of other high intensity magnetic tailings resources.
