The presence of Cr 2 O 3 was found to reduce the quality of sinter from high-chromium vanadium-titanium magnetite obtained by a blast furnace-basic oxygen furnace process. The kinetics and reaction mechanism of the solid-state reaction between Cr 2 O 3 and calcium ferrite (CF) were studied by a diffusion couple method. The phase of the product and the change in the …

Titaniferous magnetite (titanomagnetite) is nominally defined as magnetite deposits containing more than one mass percent of titanium dioxide (TiO2). Titanomagnetite deposits are known for being difficult to process; this is primarily due to the complex nature of the mineral compounds that make up the ore. The complex mineralisation means chemical upgrading processes are …

Nevertheless, BF process is still the only high–efficiency technique for smelting VTM in industry. Generally, VTM is agglomerated as sinter or pellet and then smelted in BF to obtain V–bearing hot metal and Ti–bearing BF slag [ 12 ]. Smelting VTM still has some difficulties in BF process owing to its high TiO 2 content.
