Experimental Study on Oxygen Enriched Sintering of

Nov 22, 2018 Compared with the sintering of ordinary iron ore, vanadium-titanium magnetite has lower iron, FeO, and SiO 2 contents but higher TiO 2, MgO, and Al 2 O 3 contents. These characteristics are not favorable for sintering, resulting in low production, low grade, poor strength, low yield, and high solid energy consumption of the sintered ore [ 1 , 2 ].

Titanomagnetite an overview ScienceDirect Topics

Ti x O 4) [also written xFe 2 TiO 4 (1 – x)Fe 3 O 4] forms a complete solid solution series between end members of magnetite (Fe 3 O 4) and ulv spinel (Fe 2 TiO 4). They are cubic minerals with inverse spinel structures that commonly carry the magnetic remanence of rocks; i.e. TM60 ( x = 0.6) is the dominant magnetic mineral in rapidly ...
