攀枝花白马选铁尾矿综合回收利用研究

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TiO2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。 

Research on comprehensive utilization of iron tailings from Baima Panzhihua

The Baima tailings(locaked in Panzhihua) from iron magnetic separation of a poor grade vandaium-titanium magnetite contain 5.95% TiO2 and 10.51% Fe respectively, which has not been comprehensively utilized for some reasons. This paper focus on separation ilmenite from iron tailings of a V-Ti magnetite ore in Pan Zhi Hua area，which aims on discussing the possiibility of re-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. Finanly, titanium concentrate with TiO2 grade of 47.31% and TiO2 recovery of 39.52% was achieved . Therefore, the development of this technology has build a solid technical foundation for the utilization of tailings resources, thus providing technical support for the comprehensive utilization of domestic vanadium and titanium resources.
