某低品位磁铁矿钛铁矿矿石含铁13.66%、钛3.01%，磁铁矿、钛铁矿为回收目的矿物。试验进行了“弱磁选-强磁选”和“弱磁选-摇床重选”两方案的对比，研究结果表明，“弱磁选-摇床重选”方案选矿效果较好，最终可获得铁品位60.25%、铁回收率35.57%的铁精矿和钛品位38.57%、钛回收率37.48%的钛铁矿精矿。
某低品位磁鐵礦鈦鐵礦礦石含鐵13.66%、鈦3.01%，磁鐵礦、鈦鐵礦為迴收目的礦物。試驗進行瞭“弱磁選-彊磁選”和“弱磁選-搖床重選”兩方案的對比，研究結果錶明，“弱磁選-搖床重選”方案選礦效果較好，最終可穫得鐵品位60.25%、鐵迴收率35.57%的鐵精礦和鈦品位38.57%、鈦迴收率37.48%的鈦鐵礦精礦。

A low-grade magnetite-ilmenite ore contains Fe 13.66% and TiO2 3.01%, magnetite and ilmenite are the objective mineral to recovery. “Low intensity magnetic separation-high intensity magnetic separation” and “low intensity magnetic separation-riffle gravity concentration” process flowsheet technology were used to test and comparison, “low intensity magnetic separation-riffle gravity concentration” process flowsheet got better effect: magnetite concentrate with a Fe grade and recovery of 60.25%and 35.57%, ilmenite concentrate with a TiO2 grade and recovery of 38.57%and 37.48%have been obtained.
