2016-10-1 Present study determines conditions for titanium magnetite concentrate processing with fairly complete titanium conversion to the slag and iron and vanadium separation in the hot metal. It is quite difficult to process titanium magnetite concentrate in the blast furnaces due to low fusibility of charge and direct electrical melting which cause process instability.

The titanium dioxide(TiO 2) was prepared by efficient decomposition of titanium- bearing blast furnace slag (TBBFS) in molten salt system. The as-prepared TiO 2 were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Almost complete leaching of Ti was achieved when TBBFS was carried out at 500 °C for about 3 h

Complex processing of such ores by blast furnaces is practically impossible because of formation of high-melting-point slag with a high TiO2 content. The task of efficient and complex processing of titano-magnetite ores is solved by using highly efficient cooling system of the smelting unit MAGMA that allows to use high temperatures in the ...

2020-10-1 Titanium-bearing magnetite ore is generically defined as magnetite with > 1% titanium dioxide (TiO 2) and is usually vanadium-bearing. The iron and titanium occur as a mixture of magnetite (Fe 3O 4) and ilmenite (FeTiO 3) with vanadium oxide usually occurring within the solid solution of the titanium-bearing magnetite phase.
