Natural rutile was the feedstock of choice at the early years of the Kroll process, but nowadays it comes in limited supply. Titanium dioxide slags are produced by reduction smelting of ilmenite in electric arc furnaces. The slag grade (sulfate or chloride) depends essentially on the quality of the ore or concentrate fed to the slag furnaces.
