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.
