Sulfate ilmenite is best suited for titanium slag production (both chloride and sulfate slag), as high FeO is best for pig iron formation (which is important, as pig iron can be tapped off separately in the slag furnace to leave the Ti slag) (Plester pers. commun. 2018). There can be elements in the ilmenite that carry across and make the slag ...
