某低品位钒钛磁铁矿中含TFe 18．43％，含TiO28．63％，根据矿石性质，进行了原矿磨矿-磁选工艺和粗粒抛尾-阶段选别工艺的对比试验。由试验结果可知，粗粒抛尾-阶段选别工艺更适合该矿石。对粗粒抛尾所得的精矿进行了细磨-弱磁精选工艺和粗磨-磁团聚工艺的对比试验，试验结果表明，采用粗磨-磁团聚工艺更经济、更合理。
某低品位釩鈦磁鐵礦中含TFe 18．43％，含TiO28．63％，根據礦石性質，進行瞭原礦磨礦-磁選工藝和粗粒拋尾-階段選彆工藝的對比試驗。由試驗結果可知，粗粒拋尾-階段選彆工藝更適閤該礦石。對粗粒拋尾所得的精礦進行瞭細磨-弱磁精選工藝和粗磨-磁糰聚工藝的對比試驗，試驗結果錶明，採用粗磨-磁糰聚工藝更經濟、更閤理。

A low-grade vanadium -titanium magnetite contains TFe 18.43% and TiO2 8.63%. According to the ore properties , the contrast test of direct grinding and discarding coarse tailings -stage mineral processing was carried on .It was obtained that the technology of discarding coarse tailings -stage mineral processing was more suitable for the ore .Then, the contrast test of fine grinding low-intensity magnetic separation and rough grinding magnetic coagulation was carried on the obtained concentrate .The results showed that the rough grinding magnetic coagulation has grea-ter economic advantage .
