Research and Application of Titanium Resource Recovery and Utilization Technology for a Low-grade Vanadium-titanium Magnetite
In order to comprehensively recover titanium resources from the coarse magnetic separation tailings of a low-grade vanadium-titanium magnetite ore,an experimental study on titanium recovery pro-cess was carried out based on the study of ore properties.The test results show that the ilmenite concentrate with TiO2 grade of 47.26%and TiO2 recovery of 19.34%can be obtained by the process of classification-one stage high intensity magnetic separation-grinding and low intensity magnetic separation iron removal-two stage high intensity magnetic separation-flotation,and the separation index is good.The industrial applica-tion results show that the recovery of one stage high intensity magnetic concentrate is 290 550 t,and the av-erage grade of TiO2 is 11.31%,which is higher than the quality requirements of the raw materials for titani-um separation in the beneficiation workshop.The annual profit can be increased by 31.46 million yuan,and the economic and social benefits are remarkable.
