钒钛磁铁矿尾矿综合利用研究进展

目前综合利用钒钛磁铁矿尾矿的方法主要分为两大类:尾矿再选（有价金属回收）和整体利用。根据尾矿性质与组分的不同，尾矿再选主要是采用重选、磁选、浮选、化学选矿和联合分选等选矿工艺，对尾矿中有价元素进行回收；整体利用主要是用尾矿制备建筑材料、陶瓷和瓷砖等，该方法能大量消纳尾矿，可有效解决尾矿堆存问题。基于已有的研究工作，指出对尾矿"物性"（物理化学性质）的研究是实现尾矿中有价元素回收的基础，加强联合分选工艺、细粒级有用矿物回收技术及新设备的研究是今后综合利用钒钛磁铁矿尾矿的发展方向。 

Research Progress on Comprehensive Utilization of Vanadium-Titanium Mag-netite Tailings

At present, the methods of comprehensive utilization of vanadium-titanium magnetite tailings are mainly divided into two categories: tailings reseparation (Valuable metal recycling) and overall utilization. According to the nature and composition of the tailings, in the tailings reseparation uses gravity separation, magnetic separation, flotation, chemical beneficiation and combined separation and other beneficiation processes are used mainly for recovery the valuable elements from the tailings; In overall utilization tailings are mainly used to prepare building materials, ceramics and tiles. This method can consume a large amount of tailings and can effectively solve the problem of tailings inventory. Based on the existing research work, it is pointed out that the research on the "physical properties" (physical and chemical properties) of the tailings is the basis for the recovery of valuable elements from the tailings, and strengthens the joint separation process, fine-grained useful mineral recovery technology and new equipment research is the development direction of comprehensive utilization of vanadium-titanium magnetite tailings in the future.
