Overview
Tronox Limited is a United States-based global chemicals and minerals company focused on the titanium products industry. Its principal business is titanium dioxide pigment, commonly abbreviated as TiO2, a white pigment used to provide brightness, opacity and durability in coatings, plastics, paper and other manufactured products. Tronox is distinctive among pigment producers because its operations extend upstream into mining and processing the mineral sands used to make titanium feedstocks. This vertical integration gives the company exposure to both the raw-material and finished-pigment stages of the titanium value chain. The company originated within Kerr-McGee Corporation, which had developed a substantial chemicals business alongside its oil and gas operations. Kerr-McGee separated the chemical business through a public offering in November 2005, and Tronox became an independent company in March 2006. The separation was later heavily criticized because environmental and other legacy liabilities associated with Kerr-McGee's historical operations were transferred to Tronox while Kerr-McGee retained its more valuable oil and gas assets. The inherited liabilities contributed to severe financial pressure, a collapse in Tronox's share price and a Chapter 11 bankruptcy filing in January 2009. Tronox emerged from bankruptcy protection in February 2011. Its reorganization included a litigation trust intended to pursue claims connected with the legacy environmental liabilities. The company subsequently rebuilt its operating position and expanded its mineral-sands platform. In June 2012, Tronox completed the acquisition of Exxaro Resources' mineral-sands business, combining titanium-bearing mineral-sands mining, feedstock upgrading and pigment production under the Tronox group. The transaction materially strengthened Tronox's vertical integration and made it a major participant in global titanium feedstocks as well as titanium dioxide. The company's mineral-sands activities produce or sell titanium ore and upgraded feedstocks, including ilmenite, rutile and synthetic-rutile-related materials, as well as zircon and pig iron. Mineral-sands operations and processing facilities include assets in South Africa, Western Australia and New South Wales. The company describes itself as one of the world's largest integrated producers and marketers of titanium dioxide pigment and a significant producer of titanium feedstocks and zircon. Monazite, a mineral containing rare-earth elements, is also associated with some of its mineral-sands activities. Tronox's pigment manufacturing footprint includes plants in Brazil, the United States, Australia, France, the United Kingdom and Saudi Arabia. Its products serve industrial customers rather than end consumers, with demand tied to construction, architectural and industrial coatings, paints, plastics, laminates, paper and other applications. The company also operates electrolytic and specialty-chemical businesses serving industries including paper and batteries. In April 2019, Tronox acquired Cristal Global, a Saudi Arabian titanium dioxide pigment producer. The acquisition expanded Tronox's geographic footprint and pigment capacity while reinforcing its position as a global integrated titanium dioxide supplier. Tronox announced in 2012 that it would move its headquarters from Oklahoma City to Stamford, Connecticut. Its current business identity is therefore shaped by three main developments: the separation from Kerr-McGee, the restructuring after bankruptcy connected with environmental liabilities, and expansion through mineral-sands and pigment acquisitions.
History
Tronox's corporate history is rooted in Kerr-McGee Corporation's chemicals operations. Kerr-McGee was historically active in oil and gas as well as chemical manufacturing, and its chemical division included titanium dioxide and related businesses. In the mid-2000s, Kerr-McGee separated the chemicals activities into a new publicly traded company. Tronox's initial public offering took place on November 21, 2005. The company became independent in March 2006 after Kerr-McGee distributed its remaining interest. In the first quarter of 2006, Tronox replaced Meade Instruments in the S&P SmallCap 600 index, and its Class B shares began regular-way trading on the New York Stock Exchange on March 31, 2006. The separation created a serious legacy-liability problem. Tronox inherited environmental obligations connected with decades of historical Kerr-McGee operations, while Kerr-McGee retained its oil and gas assets. The inherited sites and liabilities reportedly included contaminated chemical and fuel-related locations, radioactive waste associated with uranium and rare-earth activities, and the Henderson, Nevada, industrial site, where perchlorate contamination affected groundwater and the Lake Mead and Colorado River water system. Other sites connected with the historical operations included locations in the Navajo Nation and former wood-treatment facilities contaminated by creosote. The liabilities extended across numerous U.S. states. Tronox's financial condition deteriorated sharply during the late 2000s. Its share price fell substantially in 2008, and both classes of stock became penny stocks. In September 2008, the stock moved from the New York Stock Exchange to over-the-counter trading. On January 14, 2009, Tronox filed for Chapter 11 bankruptcy protection. The filing excluded the company's non-U.S. operations. A proposed sale of certain assets to Huntsman Corporation was announced in 2009 but was terminated later that year. The bankruptcy reorganization established an Anadarko litigation trust to pursue claims against Anadarko Petroleum, which had succeeded to Kerr-McGee. Tronox emerged from Chapter 11 on February 14, 2011. Tom Casey became chief executive officer in October 2011. The post-bankruptcy company sought to strengthen its operating platform and gain greater control over the supply of titanium feedstocks. A major turning point came on June 15, 2012, when Tronox announced completion of its acquisition of Exxaro Resources' mineral-sands business. The combined operations brought together mineral-sands mining, processing and titanium dioxide production. The transaction gave Tronox access to titanium-bearing mineral sands and upgraded feedstocks, as well as zircon and other mineral products. Tronox also announced in June 2012 that it would move its headquarters from Oklahoma City to Stamford, Connecticut. The environmental-liability dispute continued after the bankruptcy. Tronox shareholders pursued claims against Anadarko, alleging that the scope of the liabilities had not been adequately disclosed before the separation. The United States government separately pursued cleanup costs. In April 2014, the federal government and Anadarko reached a settlement exceeding $5 billion, described in the supplied reference material as the largest environmental contamination settlement in American history. The settlement addressed a broad group of historical contamination sites, including locations associated with Lake Mead, the Navajo Nation and a thorium-contaminated Superfund site in New Jersey. Tronox continued to expand its pigment business internationally. On April 10, 2019, it acquired Cristal Global, a Saudi Arabian titanium dioxide pigment manufacturer. The transaction added pigment operations and strengthened Tronox's global manufacturing and marketing network. The company has subsequently been characterized by its combination of upstream mineral-sands operations, titanium feedstock production, titanium dioxide pigment manufacturing and specialty chemical activities. Its principal industrial markets include coatings, plastics, paper and battery-related applications.

Products and positioning
A vertically integrated global titanium-products company combining mineral-sands mining, feedstock upgrading, titanium dioxide pigment manufacturing and selected specialty chemicals. Tronox primarily serves industrial customers and competes through supply-chain integration, global production capacity and access to titanium-bearing raw materials.
Pigments
Titanium dioxide pigments
Tronox's core finished product is titanium dioxide pigment, a high-opacity white material used to improve brightness, whiteness and hiding power. It is sold primarily to industrial customers serving coatings, paints, plastics, paper and related applications. The pigment business is supported by Tronox's access to internally produced titanium feedstocks and a geographically distributed manufacturing network.
Mineral products
Titanium mineral sands and feedstocks
Tronox mines titanium-bearing mineral sands and processes them into higher-grade feedstock materials used in titanium dioxide production and other downstream applications. The portfolio includes titanium ore and upgraded materials derived from minerals such as ilmenite and rutile. This upstream position is central to the company's vertically integrated business model.
Mineral products
Zircon
Zircon is recovered from mineral-sands operations and sold directly to customers. It is an important coproduct of titanium-mineral production and is used in ceramic, foundry, refractory and other industrial applications. Tronox has been identified as one of the world's significant zircon producers.
Mineral products
Pig iron and other mineral coproducts
Tronox's mineral-sands upgrading operations produce pig iron and other mineral products alongside titanium feedstocks. These materials broaden the commercial output of the company's mines and processing facilities beyond titanium dioxide inputs.
Specialty chemicals
Electrolytic and specialty chemicals
The company has also operated electrolytic and specialty-chemical activities serving industrial customers, including the paper and battery sectors. These businesses complement the larger titanium-products platform but are less central to Tronox's public identity than pigments and mineral sands.
Controversies
2014
Federal environmental settlement involving Anadarko
The United States reached a settlement exceeding $5 billion with Anadarko over cleanup obligations connected with historical Kerr-McGee operations. The affected sites included locations associated with Lake Mead contamination, uranium-related waste in and around the Navajo Nation and other former industrial facilities.
2009
Legacy environmental liabilities and investor litigation
After the Kerr-McGee separation, Tronox inherited extensive historical environmental obligations, including contaminated chemical, radioactive-material and industrial sites. Shareholders sued Anadarko Petroleum, Kerr-McGee's successor, alleging that investors had not been adequately informed about the liabilities transferred to Tronox. The dispute contributed to Tronox's bankruptcy and led to the creation of a litigation trust during its reorganization.
