Tronox Holdings plc

Tronox is the world’s leading vertically integrated manufacturer of TiO 2 pigment. We operate titanium-bearing mineral sand mines and beneficiation and smelting operations in Australia and South Africa to produce feedstock materials that can be processed into TiO 2 for pigment, high purity titanium chemicals, including titanium tetrachloride, and ultrafine TiO 2 used in certain specialty applications. Our strategy is to be vertically integrated and produce enough feedstock materials to be as self-sufficient as possible in the production of TiO 2 at our seven pigment facilities located in the United States, Australia, Brazil, UK, France, and the Kingdom of Saudi Arabia. We believe that vertical integration is the best way to achieve our ultimate goal of delivering low cost, high-quality pigment to our approximately 1,200 TiO 2 customers throughout the world. The mining, beneficiation and smelting of titanium bearing mineral sands also creates meaningful quantities of co-products including zircon, pig iron and the rare-earth bearing mineral, monazite, which we also supply to customers around the world.
