2021-6-11 The comprehensive utilization of vanadium-titanium magnetite ore (VTM) has always been a hot topic in metallurgy research. In the blast furnace ironmaking process, significantly increasing the content of VTM can effectively improve the recovery and utilization of vanadium-titanium resources.[1,2,3] Unfortunately, serious slagging difficulties, such as slag foaming and poor fluidity of the slag ...

A total of 100 kg of the raw hematite ore sample was first crushed using a jaw crusher and then sieved to a size of 2 mm in our laboratory. One kilogram of each of the 12 samples of the crushed hematite ore was then reduced to magnetite ore, under a total volumetric gas rate of 120 L/h, using a gas mixture of 50% H 2 –50% N 2. The reduction ...
