In the titaniferous magnetite coarse particle, white grains (point 1) with a particle size of 3–5 μm and gray grains (point 2) with a particle size about 0.5 μm were distributed widely. EDS analysis showed that point 1 was the magnetite containing 4.75 wt % titanium, and point 2 was Fe 2 O 3 ·FeTiO 3 containing 15.31 wt % titanium.

Artificial rich ore for blast furnace use can be produced by sintering ultra-poor vanadium-titanium magnetite (PVTM) with a high-grade iron concentrate. Here, acid (R = 0.33, 0.50), self-fluxing (R = 1.10), and high-basicity (R = 2.60) PVTM sinters were produced in a sinter pot. Their performances were determined using the comprehensive …
