Features of the Reducibility of Titanomagnetite Iron Ore Materials

Abstract:

The reducibility of titanomagnetite iron ore materials (agglomerate, pellets) with various TiO₂ contents are studied. The mineralogical features of agglomerate and pellets before and after reduction are investigated. Calculations of technical and economic indicators of blast furnace smelting using iron ore materials with different TiO₂ contents are carried out. It is shown that an increase in the content of titanium dioxide in pellets and agglomerate (with an increase in the amount of concentrate introduced into them) does not change the quality of iron ore preparation for blast furnace smelting.
