我国钒钛磁铁矿资源丰富,最具代表性的攀枝花地区钒钛磁铁矿的选矿多是经弱磁选铁后,磁选尾矿再选钛.用于选钛的矿石中主要含钛矿物是钛铁矿,但仍有少量残余的钛磁铁矿.在磁选尾矿的浮选中,钛磁铁矿具有比钛铁矿更好的可浮性,同时由于残余磁铁矿的剩磁较大,加之磨矿加剧了磁团聚,部分脉石会随钛磁铁矿一起进去精矿,从而影响品位和回收率,也造成药剂的浪费.钒钛磁铁矿浮钛时残余钛磁铁矿有十分不利的影响,应在浮选前采取多次弱磁处理,尽量把钛磁铁矿去除干净.
China’s vanadium-titanium magnetite is rich in resources, the most representative of Panzhihua vanadium-titanium magnetite beneficiation is mostly after the weak magnetic separation of iron, magnetic separation of tailings re-election of titanium. Titanium ore for the main titanium The mineral is ilmenite, but there is still a small amount of residual titanium magnetite.In the flotation of magnetic tailings, the titanomagnetite has better floatability than the ilmenite, and at the same time due to the residual magnetite More remanence, combined with grinding aggravate the magnetic agglomeration, some gangue will join the magnetite together with the concentrate, thus affecting the grade and recovery, but also result in the waste of chemicals. Magnetite has a very adverse impact, should be taken before the flotation weak magnetic treatment, try to remove the titanium magnetite clean.
