Buddy D. Ratner, Guigen Zhang, in Biomaterials Science (Fourth Edition), 2020 Titanium. In 1791, William Gregor, a Cornish amateur chemist, used a magnet to extract the ore that we now know as ilmenite from a local river. He then extracted the iron from this black powder with hydrochloric acid, and was left with a residue that was the impure oxide of titanium.
The current rate of industrial production of titanium dioxide, from natural ilmenite, is around 6500 kT per annum. The two main processes used, namely, sulfate and chloride processes, require concentrated corrosive acids and drastic conditions, such as 1000 °C, in open processes, thus contributing to considerable costs and environmental pollution.
The addition of sodium fluoride to the ilmenite sample, for example, in a mass ratio of 1:1 increased the degree of titanium extraction by almost six times in 60 min of leaching. The X ( t ) dependences on the initial sections had the form of convex curves, and the curves were well approximated by straight lines from the moment the reaction ...
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 carbo-chlorination process (described below) that converts TiO2 into TiCl4.
The mineral ilmenite is an iron-titanium oxide (FeTiO 3) which is concentrated within small oxide-bearing ultramafic intrusions (OUI) associated with the Duluth Complex in northeastern Minnesota.
