Tronox Announces Completion of Agreement with RTI for New Titanium Sponge Facility at Hamilton, Miss., Site

Oklahoma City, March 25, 2008 – Tronox Incorporated (NYSE: TRX, TRX.B) today announced that its wholly owned subsidiary Tronox LLC signed a definitive agreement with RTI International Metals, Inc. under which RTI will purchase titanium tetrachloride (TiCl4) from Tronox’s Hamilton, Miss., titanium dioxide plant. The TiCl4 will be used in the manufacturing of titanium sponge at a new plant that RTI will build adjacent to Tronox’s Hamilton facility. Tronox expects to generate annual operating profits from TiCl4 sales and incremental cost savings in the range of $12 million to $15 million once the plant reaches full production. RTI estimates the plant will come on line in 2010, ramping up production over the next several years.

“This project will add incremental value to our world-class Hamilton facility and is just one example of our business development efforts to create long-term value for the company,” said Tom Adams, Tronox chairman and chief executive officer. “A talented team of Tronox employees from both the Hamilton plant and corporate office leveraged our pigment technical expertise as they successfully pursued this new business opportunity. With our industry experience and co-existing facilities, we expect to achieve synergies that result in long-term cost savings and create incremental value for both our pigment and electrolytic businesses in Hamilton.

“I want to thank Governor Haley Barbour, the Mississippi Development Authority and the Monroe County Chamber of Commerce for helping us attract this global manufacturer to Hamilton. Their continued efforts to grow the Mississippi economy are truly making a difference in the state’s business environment and quality of life,” said Adams. “In addition, I want to welcome RTI to Hamilton and to our new business partnership. We are committed to continuing our joint technical and commercial work during construction of the facility, and look forward to being a long-term supplier to RTI and continuing our joint integration efforts as neighboring facilities.”

As a chloride pigment producer, Tronox has expertise in the production of TiCl4, which is a key input for its product, titanium dioxide pigment, and also RTI’s titanium sponge, used in the manufacture of titanium metal for aircraft, military equipment and chemical, medical and customer applications. The titanium metals market is projected to experience significant growth over the next decade.

Headquartered in Oklahoma City, Tronox is the world’s third-largest producer and marketer of titanium dioxide pigment, with an annual production capacity of 642,000 tonnes. Titanium dioxide pigment is an inorganic white pigment used in paint, coatings, plastics, paper and many other everyday products. The company’s five pigment plants, which are located in the United States, Australia, Germany and the Netherlands, supply high-performance products to approximately 1,100 customers in 100 countries. In addition, Tronox produces electrolytic products, including sodium chlorate, electrolytic manganese dioxide, boron trichloride, elemental boron and lithium manganese oxide.
