The titanium rich slag was produced from the low-grade ilmenite concentrate, i.e. the low TiO 2 content and the high content of impurities. During the production of the high-grade titanium slag (TiO 2 content: 75–80%), the impurity elements are transferred into the associated alloyed metal (cast iron). Thus, it can be used to smelt the steel.
