Ilmenite, iron-black, heavy, metallic oxide mineral, composed of iron and titanium oxide (FeTiO3), that is used as the major source of titanium. It forms solid-solution series with geikielite and pyrophanite in which magnesium and manganese, respectively, replace iron in the crystal structure.
The phase equilibrium information of slag plays an important role in pyrometallurgical processes to obtain optimum fluxing conditions and operating temperatures. The smelting reduction of titanomagnetite and ilmenite ores in an iron blast furnace (BF) can form Ti(C,N) particles, causing the increased viscosities of slag and …
A green separation routes for Fe and Ti from ilmenite via molten salt electrolysis is proposed in CaCl 2-NaCl-CaO molten salt.FeTiO 3 powder can be dissolved into the molten salt, directly.
