% titanium is in the iron concentrate after mineral processing, after smelting process the blast furnace slag containing 20%-22% TiO2 were produced[1]. The content of TiO2 in the slag is too low to separate titanium dioxide, and it is also too high to produce slag cement[2]. This slag has been already accumulated 50 million tons so far, and it is still increasing with a rate of 3 million tons per......
is vanadium-titanium bearing magnetite, deposited mostly around the southwestern part. About 53% titanium is in the iron concentrate after mineral processing, after smelting process the blast furnace slag containing 20%-22% TiO2 is produced[1]. Several mineral processing and metallurgical processes have been proposed for treating the slag[2-4], however, owing to the dispersed distribution of titanium......
