2 dagar sedan· Titanium processing Titanium processing Extraction and refining: The production of titanium metal accounts for only 5 percent of annual titanium mineral consumption; the rest goes to the titanium pigment industry. Pigments are produced using either a sulfate process or a more environmentally acceptable carbochlorination process (described below) that converts TiO2 into TiCl4.

· 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.
