Current Situation and Outlook of Iron, Titanium and Phosphorus Beneficiation of Ultra-poor Vanadic Titanomagnetite in Chengde

Objective To mainly summarize the research progress on the development and utilization of iron, titanium and phosphorus resources and the beneficiation separation process in Chengde ultra-low vanadium-titanium magnetite. Method Through literature review, the current research status of iron, titanium and phosphorus beneficiation in Chengde ultra-low vanadium-titanium magnetite is analyzed, and the existing technical situation of the development and utilization of Chengde ultra-low vanadium-titanium magnetite is systematically sorted out. Result At present, the development of ultra-poor vanadium-titanium magnetite in Chengde area has reached a certain scale. The mainstream iron separation process adopts the combined process of strong magnetic - flotation, and is equipped with technologies such as high-pressure roller grinding, dry/wet pre-selection, stage grinding and stage weak magnetic separation. Phosphorus selection mainly relies on coarse and fine classification - flotation process, but the overall comprehensive utilization level is relatively low, and the recovery problem of fine-grained titanium and phosphorus minerals has not been effectively solved. Conclusion Subsequently, research on microbubble flotation processes for fine-grained titanium and phosphate minerals should be carried out, high-selectivity collectors should be developed, and the flotation reagent system should be optimized, so as to achieve efficient and comprehensive utilization of ultra-poor vanadium-titanium magnetite resources.
