Experimental Study on Oxygen-Enriched Sintering of

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 ].
