To address the problems of high titanaugite silicate content in ilmenite and the low recovery of the existing gravity separation process from a certain area in Xinjiang, a systematic experimental study on flotation was conducted. Under the conditions of a raw ore TiO2 grade of 15.64% and an ilmenite distribution rate of 77.37%, using a composite binary organic acid as the titanaugite depressant and adopting the beneficiation process flowsheet of "desulfurization reverse flotation-ilmenite direct flotation", an ilmenite concentrate with a yield of 26.02%, a TiO2 grade of 45.62%, and a recovery of 76.27% was obtained through the closed-circuit test. Compared with the existing gravity separation process, the TiO2 recovery rate in ilmenite concentrate by high intensity magnetic separation-flotation process is increased by 8.1 precentage points, and the ilmenite content in the concentrate reached 91.22%, which achieved the effective flotation separation of ilmenite and titanaugite. Zeta potential measurements and adsorption tests indicate that the composite binary organic acid has a greater impact on the surface potential of titanaugite and a higher adsorption amount, which increases the floatability difference between titanaugite and ilmenite, and provides a basis for their flotation separation.

针对新疆某地钛铁矿中钛辉石硅酸盐含量高、现有重选工艺回收率低等问题，开展了系统的浮选试验研究。在原矿TiO2品位为15.64%，钛铁矿分布率达到77.37%的条件下，以复合二元有机酸为钛辉石抑制剂，采用“脱硫反浮选-钛铁矿正浮选”的选矿工艺流程，闭路试验获得了产率为26.02%，TiO2品位为45.62%、回收率为76.27%的钛精矿，采用强磁-浮选工艺的钛精矿TiO2回收率较现有重选工艺提高了8.1个百分点，精矿中钛铁矿含量达91.22%，实现了钛铁矿与钛辉石的有效浮选分离。Zeta电位测定和吸附量测试表明，复合二元有机酸对钛辉石表面电位影响更大、吸附量更高，增大了钛辉石与钛铁矿的可浮性差异，为二者分离浮选提供了依据。

针对新疆某地钛铁矿中钛辉石硅酸盐含量高、现有重选工艺回收率低等问题，开展了系统的浮选试验研究。在原矿TiO2品位为15.64%，钛铁矿分布率达到77.37%的条件下，以复合二元有机酸为钛辉石抑制剂，采用“脱硫反浮选-钛铁矿正浮选”的选矿工艺流程，闭路试验获得了产率为26.02%，TiO2品位为45.62%、回收率为76.27%的钛精矿，采用强磁-浮选工艺的钛精矿TiO2回收率较现有重选工艺提高了8.1个百分点，精矿中钛铁矿含量达91.22%，实现了钛铁矿与钛辉石的有效浮选分离。Zeta电位测定和吸附量测试表明，复合二元有机酸对钛辉石表面电位影响更大、吸附量更高，增大了钛辉石与钛铁矿的可浮性差异，为二者分离浮选提供了依据。

To address the problems of high titanaugite silicate content in ilmenite and the low recovery of the existing gravity separation process from a certain area in Xinjiang, a systematic experimental study on flotation was conducted. Under the conditions of a raw ore TiO2 grade of 15.64% and an ilmenite distribution rate of 77.37%, using a composite binary organic acid as the titanaugite depressant and adopting the beneficiation process flowsheet of "desulfurization reverse flotation-ilmenite direct flotation", an ilmenite concentrate with a yield of 26.02%, a TiO2 grade of 45.62%, and a recovery of 76.27% was obtained through the closed-circuit test. Compared with the existing gravity separation process, the TiO2 recovery rate in ilmenite concentrate by high intensity magnetic separation-flotation process is increased by 8.1 precentage points, and the ilmenite content in the concentrate reached 91.22%, which achieved the effective flotation separation of ilmenite and titanaugite. Zeta potential measurements and adsorption tests indicate that the composite binary organic acid has a greater impact on the surface potential of titanaugite and a higher adsorption amount, which increases the floatability difference between titanaugite and ilmenite, and provides a basis for their flotation separation.
