The pre-concentration and tailings discarding technique was adopted in the processing of vanadium-titanium magnetite in Panxi region. Based on analysis and summarization, it is found that the ores in the Baima Mine belongs to low TiO₂-grade vanadium-titanium magnetite, and pre-concentration and tailings discarding process can be adopted. As for pre-concentration, medium-intensity magnetic separator (MIMS) is suitable for discarding larger lumps (-300 mm), a process of roughing with MIMS combined with scavenging with MIMS is suitable for discarding small lumps (-40 mm), and wet high-intensity magnetic separator is suitable for discarding coarser-grained ore (-12 mm or-5 mm). As a result, the TiO₂ grade of final discarded tailings can be finally controlled within 2.5%. However, the vanadium-titanium magnetite in Panzhihua, Hongge and Taihe mines have a high grade of titanium, for which it is appropriate to adopt the above-mentioned processes for pre-concentration and discarding of small lump (-25 mm) ores and coarser-grained ores. And after classification of the tailings, the finer fraction is sent for titanium separation, leading to the TiO₂ grade of the final discarded tailings within 3.5%. It is shown that the above-mentioned processing technique and flowchart can greatly discard qualified tailings, which can provide a reference for development and utilization of similar resources.

对预选抛尾技术在攀西钒钛磁铁矿中的应用情况进行了分析和总结。结果表明：白马矿区矿石属低钛型钒钛磁铁矿，可采用大块、小块和粗粒进行预选抛尾，其中大块抛尾宜采用中磁选，小块抛尾宜采用中磁选粗选+中磁选扫选，粗粒抛尾宜采用湿式强磁选，可将最终抛尾尾矿TiO₂品位控制在2.5%以内；攀枝花、红格和太和矿区矿石属于高钛型钒钛磁铁矿，不宜采用大块抛尾，可采用小块和粗粒进行预选抛尾，其中小块抛尾宜采用中磁选粗选+强磁选扫选，粗粒抛尾宜采用湿式强磁选，其尾矿进行分级后，细粒级进入选钛系统，可将最终抛尾尾矿TiO₂品位控制在3.5%以内。上述抛尾方式和流程能大幅抛出合格尾矿，可为同类型资源的开发利用提供参考。
