摘要/Abstract

摘要： 针对攀西地区某钒钛磁铁矿选矿厂工艺流程长、生产效率低等问题,使用X 射线衍射仪、X 射线荧光分
析仪、振动磁强计等仪器,分析了现场塔磨机排矿的矿物组成与金属分布规律、不同粒级的磁化特性等,并借助三产
品磁选柱进行了分选试验。结果表明,该矿样中主要含铁矿物为钛磁铁矿和钛铁矿,主要脉石矿物为辉石。原矿TFe
品位为55. 34%,TiO2 品位为11. 36%,-0. 074 mm 粒级含量为87. 21%,Fe 分布率为89. 11%,TiO2 分布率为86. 81%。
经过三产品磁选柱分选,获得的精矿、中矿和尾矿的TFe 品位分别为60. 02%、54. 03%和22. 96%,回收率分别为50.
68%、47. 33%和1. 99%,TiO2 的品位分别为9. 98%、10. 52%、29. 92%,回收率分别为68. 05%、17. 90%和14. 05%。采
用三产品磁选柱能够从塔磨机排矿中直接获得合格铁精矿,同时实现钛资源的高效回收,降低了后续选矿成本,为同
类矿石的高效分选提供了新的技术途径。

Abstract: Aiming at the problems of long process flow and low production efficiency of a vanadium-titanium magnetite
ore dressing plant in the Panxi area,using X-ray diffractometers,X-ray fluorescence analyzers,and vibrating sample magnetometers,
the mineral composition and metal distribution patterns of the on-site tower mill discharge ore,as well as the magnetization
characteristics of different particle sizes,were analyzed,and carried out sorting tests with the help of three-product magnetic
separator columns. The results show that the main iron-bearing minerals in the ore sample are titanomagnetite and ilmenite,
with main gangue mineral of pyroxene. The grade of TFe is 55. 34%,the grade of TiO2 is 11. 36%,the content of -0. 074 mm
grain size is 87. 21%,the distribution rate of Fe is 89. 11%,and the distribution rate of TiO2 is 86. 81%. After the three-product
magnetic separation column sorting,the TFe grades of the obtained concentrate,middle ore,and tailings were 60. 02%,54.
03%,and 22. 96%,with recoveries of 50. 68%,47. 33%,and 1. 99%,respectively. The grades of TiO2 were 9. 98%,10. 52%,
and 29. 92%,with recoveries of 68. 05%,17. 90%,and 14. 05%. Using a three-product magnetic separation column can obtain
qualified iron ore concentrate directly from the tower mill discharge and,at the same time,realize the efficient recovery of titanium
resources,reduce the subsequent beneficiation cost,and provide a new technical way for the efficient sorting of similar
ores.
