摘要
攀枝花白马低品位钒钛磁铁矿选铁尾矿含钛5.59%,含铁10.51%,由于某些特殊原因一直没有开发利用。本文主要针对攀枝花白马钒钛磁铁矿选铁尾矿中再回收钛资源进行了研究,其目的在探讨该资源二次开发利用的可行性。根据铁尾矿工艺矿物学性质,分别开展了磁场强度、磨矿细度、冲程、冲次、转速等变量对磁选指标的影响,最终开发了适应于处理该尾矿的高梯度磁选-浮选联合工艺。试验结果表明,采用该工艺能够获得TiO_2品位47.31%、回收率39.52%的钛精矿产品。该技术的开发为后期尾矿资源化的开发奠定了坚实的技术基础,从而为国内同类钒钛资源的综合利用提供技术支撑。
The iron tailing of Baima vanadium-titanium magnetite in Panzhihua contains 5.59%titanium and 10.51%iron,but it has not been developed and utilized for some special reasons.This paper focuses on the recovery of titanium resources from the separation tailings of vanadium-titanium magnetite in Panzhihua to explore the feasibility of the secondary development and utilization of the resources.According to the mineralogy of iron tailings,the effect of magnetic field intensity,grinding fineness,magnetic stroke,specific water-cycle and rotary speed on the separation results were studied.Therefore,a combination beneficiation flowsheet of high gradient magnetic separation-flotation was developed.Finally,the titanium concentrate with TiO2 grade of 47.31%and TiO2 recovery of 39.52%was achieved.Therefore,the development of this technology has built a solid technical foundation for the utilization of tailings resources,thus providing technical support for the comprehensive utilization of domestic vanadium and titanium resources.
