摘要：

In this research, ferrotitanium was produced from titania slag by an aluminothermic process in an Electro Slag Crucible Melting (ESCM) furnace. The effect of Al and flux additions on titanium recovery, ferrotitanium yield and Ti/Al ratio were studied. It was found that an increase in Al amount led to a decrease in Ti recovery and Ti/Al ratio, in addition to an increase in ferrotitanium yield. Furthermore, increasing the flux amount led to an increase in ferrotitanium yield and Ti/Al ratio. X-ray diffraction (XRD) patterns of the ferrotitanium slag showed that the titanium recovery declined due to the formation of titanium suboxides and tialite in slag. Analysis of ferrotitanium samples, prepared in various conditions, were 45-54.5% Ti, 6-11% Al, 9-11% Si, 0.7-0.9% C, 1.6-2 % Mn, 0.07-0.08 % P and 0.004-0.009% S. © Canadian Institute of Mining, Metallurgy and Petroleum.
