Abstract:
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.
