摘要

摘要: 为查清新疆某低品位难选钒钛磁铁矿的矿石性质及影响选矿指标的因素，开展了详细的工艺矿物学研究。结果表明：该矿石为辉长岩型低品位钒钛磁铁矿，矿石TiO₂品位4.53%、TFe品位14.06%，其它有价元素含量低。钛磁铁矿为选矿回收铁元素的目的矿物，其中铁的分布率占总铁的47.892%，钛铁矿为选矿回收钛元素的目的矿物，其钛的分布率占总钛的60.881%。钛磁铁矿中常见固溶体分离矿物、蚀变矿物绿泥石及磷灰石等，粒度微细、嵌布复杂，磨矿难以与钛磁铁矿有效解离，易混入铁精矿影响铁精矿品质；钛铁矿中亦包含有微量蚀变矿物榍石及微细粒钛磁铁矿、磷灰石及硫化物等，混入钛精矿将导致钛精矿中Ca、Mg、Si、S、P等含量升高，影响精矿质量。同时，钛磁铁矿中的片晶状钛铁矿及钛铁晶石磨矿难以有效解离，在选铁环节易随钛磁铁矿进入铁精矿，这部分钛铁矿属于合理损失。

Abstract: In order to find out the ore properties of a low-grade refractory vanadium-titanium magnetite ore and the factors affecting the beneficiation index, carried out detailed process mineralogy research. The research shows that the ore is a low-grade vanadium-titanium magnetite ore of gabbro type. The grade of TiO₂ is 4.53 %, the grade of TFe is 14.06% and the content of other valuable elements is low. Titanomagnetite is the target mineral for beneficiation recovery of iron, in which the distribution rate of iron accounts for 47.892% of the total iron. Ilmenite is the target mineral for beneficiation recovery of titanium, and its distribution rate of titanium accounts for 60.881% of the total titanium. The solid solution separation minerals, altered minerals chlorite and apatite are common in titanomagnetite. The particle size is fine and the dissemination is complex. It is difficult to effectively dissociate from titanomagnetite by grinding, and it is easy to be mixed with iron concentrate to affect the quality of iron concentrate. The ilmenite also contains trace alteration minerals such as titanite and fine-grained titanomagnetite, apatite and sulfide. The addition of titanomagnetite to the ilmenite concentrate will lead to the increase of Ca, Mg, Si, S and P in the ilmenite concentrate, which will affect the quality of the concentrate. At the same time, the lamellar ilmenite and ilmenite in titanomagnetite are difficult to be effectively dissociated by grinding, and it is easy to enter the iron concentrate with titanomagnetite in the iron separation process. This part of ilmenite is a reasonable loss.
