对于加拿大马尼托巴省派普斯通湖含钒的钛磁铁矿矿床，现已在实验室开发出一种火冶和水治相结合的方法，以回收钛、钒和铁。矿石含Fe57．5％、V0.66％和TiO216．6％．矿石经过选择还原熔炼，因此，大部分的铁存在于金属相中，而钒和钛则存在于渣相中．铁的纯度达到99％，渣中含FeO9％～35％、ToO231％～46％和V1．2％～1．6％．98％以上的钛和钒成为渣相。渣在950℃的条件下，用苏打发焙烧，然后用80℃的热水浸析以回收钒。浸析后的残余物在105℃的条件下再用盐酸加以处理，主要除去铁、镁和铝，以提高TiO2的含量。最终产品含TiO282．9％、FeO1.5％、SiO215．6％、MgO1％、Al2O32％和CaO0.3％；钛的总回收率为90％以上。这种产品可用作颜料工业的原料．
For the vanadium-bearing vanadium-bearing titanium magnetite deposit in Lake State, Manitoba, Canada, a combination of firemaking and water treatment has been developed in the laboratory to recover titanium, vanadium and iron. Ore containing Fe57.5%, V0.66% and TiO216.6%. The ore is selectively reduced and smelted, so most of the iron is present in the metal phase, while vanadium and titanium are present in the slag phase. Iron purity of 99%, slag containing FeO9% ~ 35%, ToO231% ~ 46% and V1.2% ~ 1.6%. More than 98% of titanium and vanadium become the slag phase. Slag was fired at 950 ° C using baking soda and then leached with hot water at 80 ° C to recover vanadium. The leached residue is then treated with hydrochloric acid at 105 ° C to remove iron, magnesium and aluminum, in order to increase the TiO2 content. The final product contains TiO282.9%, FeO1.5%, SiO215.6%, MgO1%, Al2O32% and CaO0.3%; the total recovery of titanium is above 90%. This product can be used as a raw material for the pigment industry.
