Unless otherwise indicated or required by context, as used in this prospectus, references to “we,” “us,” and “our” refer to Tronox Limited (as defined below), when discussing the business following completion of the Transaction (as defined below), and to Tronox Incorporated (as defined below), when discussing the business prior to completion of the Transaction.

Our Company

Overview

Tronox Limited, a public limited company registered under the laws of the State of Western Australia, Australia, and its subsidiaries (collectively referred to as “Tronox” or “the Company”) is a global leader in the production and marketing of titanium- bearing mineral sands and titanium dioxide pigment (“TiO₂”). Our world-class, high performance TiO₂ products are critical components of everyday applications such as paint and other coatings, plastics, paper and other applications. Our mineral sands business consists primarily of two product streams—titanium feedstock and zircon. Titanium feedstock is used primarily to manufacture TiO₂. Zircon, a hard, glossy mineral, is used for the manufacture of ceramics, refractories, TV glass and a range of other industrial and chemical products. We have global operations in North America, Europe, South Africa and Australia.

Tronox Limited was formed on September 21, 2011 for the purpose of the Transaction (see below). Prior to the completion of the Transaction, the Company was wholly-owned by Tronox Incorporated, and had no operating assets or operations. Tronox Incorporated, a Delaware corporation (“Tronox Incorporated”), was formed on May 17, 2005, in preparation for the contribution and transfer by Kerr-McGee Corporation of certain entities, including those comprising substantially all of its chemical business into a separate operating company.

For the three months ended March 31, 2013, we had net sales of $470 million, adjusted EBITDA of $73 million and a net loss attributable to Tronox Limited of $57 million. As of March 31, 2013, we had approximately $2,411 million of total indebtedness outstanding. For the year ended December 31, 2012, we had net sales of $1,832 million, adjusted EBITDA of $503 million and net income attributable to Tronox Limited of $1,134 million. As of December 31, 2012, we had approximately $1,645 million of total indebtedness outstanding.

Acquisition of Mineral Sands Operations

Consistent with our strategy to become a fully integrated global producer of mineral sands and TiO₂ with production facilities and sales and marketing presence strategically positioned throughout the world, on June 15, 2012 (the “Transaction Date”), we combined the existing business of Tronox Incorporated with Exxaro Resources Ltd’s (“Exxaro”) mineral sands operations, which includes its Namakwa Sands and KwaZulu-Natal (“KZN”) Sands mines, separation and slag furnaces in South Africa, along with Exxaro’s 50% share of the Tiwest Joint Venture in Western Australia (together, the “mineral sands business”) (the “Transaction”).

The Transaction was completed in two principal steps. First, Tronox Incorporated became a subsidiary of Tronox Limited, with Tronox Incorporated shareholders receiving one Class A ordinary share (“Class A Share”) and $12.50 in cash (“Merger Consideration”) for each Tronox Incorporated common share. Second, Tronox Limited issued 9,950,856 Class B ordinary shares (“Class B Shares”) to Exxaro and one of its subsidiaries in

consideration for the mineral sands business. Upon completion of the Transaction, former Tronox Incorporated shareholders held 15,413,083 Class A Shares and Exxaro held 9,950,856 Class B Shares, representing approximately 60.8% and 39.2%, respectively, of the voting power in Tronox Limited. Exxaro retained a 26% ownership interest in the South African operations that are part of the mineral sands business in order to comply with the Black Economic Empowerment (“BEE”) legislation of South Africa.

During 2012, we repurchased approximately 12.6 million Class A Shares, which was approximately 10% of our total voting securities. During October 2012, Exxaro purchased 1.4 million Class A Shares in market purchases. At March 31, 2013 and December 31, 2012, Exxaro held approximately 44.4% and 44.6%, respectively, of our voting securities.

Prior to the Transaction Date, Tronox Incorporated and Exxaro Australia Sands Pty Ltd., a subsidiary of Exxaro, operated the Tiwest Joint Venture, which included a chloride process TiO₂ plant located in Kwinana, Western Australia, a mining operation in Cooljarloo, Western Australia, and a mineral separation plant and a synthetic rutile processing facility, both in Chandala, Western Australia. As part of the Transaction, we acquired Exxaro Australia Sands Pty Ltd. and therefore Exxaro’s 50% interest in the Tiwest Joint Venture. As such, as of the Transaction Date, we own 100% of the operations formerly operated by the Tiwest Joint Venture.

Principal Business Lines

Subsequent to the Transaction, we have two reportable operating segments, Mineral Sands and Pigment. Additionally, our corporate activities include our electrolytic manufacturing and marketing operations.

Mineral Sands Operations

The Mineral Sands segment includes the exploration, mining and beneficiation of mineral sands deposits. “Mineral sands” refers to concentrations of heavy minerals in an alluvial environment (sandy or sedimentary deposits near a sea, river or other water source). We separate these minerals from these primary sources. We process ilmenite into either slag or synthetic rutile. Other than zircon, all of these materials are sometimes referred to as titanium feedstock. Titanium feedstock is the most significant raw material used in the manufacture of TiO₂.

We acquired the mineral sands business from Exxaro on the Transaction Date. The mineral sands business operations are comprised of the KZN Sands and Namakwa Sands mines, both located in South Africa, and Cooljarloo Sands mine located in Western Australia, which have a combined production capacity of 753,000 metric tons (“tonnes”) of titanium feedstock and 265,000 tonnes of zircon. The KZN Sands operations involve the exploration, mining and beneficiation of mineral sands deposits in the KwaZulu-Natal province of South Africa, and the Namakwa Sands operations involve the exploration, mining and beneficiation of mineral sands deposits in the Western Cape province of South Africa. The Tiwest operations conduct the exploration, mining and processing of mineral sands deposits and the production of titanium dioxide pigment in Western Australia.

We are the third largest global producer of titanium feedstock and a global leader in zircon production. Titanium feedstock is the most significant raw material used in the manufacture of TiO₂. We believe annual production of titanium feedstock from our mineral sands operations will continue to exceed the raw material supply requirement for our TiO₂ operations. Zircon is primarily used for the manufacture of ceramics, a market which has grown substantially during the previous decade and is favorably positioned to long-term development trends in the emerging markets, principally China.

The table set forth under “The Businesses—Property—Mineral Reserves” summarizes Tronox Limited’s proven and probable ore reserves and estimated mineral resources as of December 31, 2012.

Pigment Operations

We are the world’s third-largest producer and marketer of TiO₂ manufactured via chloride technology. The pigment segment primarily produces and markets TiO₂, and has production facilities at the following locations: Hamilton, Mississippi; Botlek, the Netherlands; and Kwinana, Western Australia, representing an aggregate of 465,000 tonnes of annual TiO₂ production capacity.

TiO₂ is used in a wide range of products due to its ability to impart whiteness, brightness and opacity, and is designed, marketed and sold based on specific end-use applications. TiO₂ is used extensively in the manufacture of paint and other coatings, plastics and paper and in a wide range of other applications, including inks, fibers, rubber, food, cosmetics and pharmaceuticals. According to TZMI data, the paint and coatings sector is the largest consumer of pigment averaging approximately 58% of total pigment consumption in 2011. The plastics sector accounted for approximately 22% of TiO₂ consumption in 2011, while the remaining 20% was divided between paper, inks, fibers and other.

TiO₂ is a critical component of everyday consumer applications due to its superior ability to cover or mask other materials effectively and efficiently relative to alternative white pigments and extenders. TiO₂ is considered to be a quality of life product and some research indicates that consumption generally increases as disposable income increases. We believe that, at present, TiO₂ has no effective mineral substitute because no other white pigment has the physical properties for achieving comparable opacity and brightness or can be incorporated in as cost-effective a manner.

We supply and market TiO₂ under the brand name TRONOX^® to more than 1,000 customers in approximately 90 countries, including market leaders in each of the key end-use markets for TiO₂, and have supplied each of our top ten customers with TiO₂ for more than ten years. These top ten customers represented approximately 46% of our total TiO₂ sales in 2012. The tables below summarize our 2012 TiO₂ sales volume by geography and end-use market:

We operate three TiO₂ facilities at the following locations: Hamilton, Mississippi; Botlek, the Netherlands; and Kwinana, Australia, representing an aggregate of 465,000 tonnes of annual TiO₂ production capacity. We are one of a limited number of TiO₂ producers in the world with chloride production technology, which we believe is preferred for many of the largest end-use applications compared to TiO₂ manufactured by other TiO₂ production technologies. We hold more than 200 patents worldwide and have a highly skilled work force.

Electrolytic and Other Chemical Products Operations

Our electrolytic and other chemical products operations are primarily focused on advanced battery materials, sodium chlorate and specialty boron products. Battery material end-use applications include alkaline batteries for flashlights, electronic games, medical and industrial devices as well as lithium batteries for power tools, hybrid electric vehicles, laptops and power supplies. Sodium chlorate is used in the pulp and paper industry in pulp bleaching applications. Specialty boron product end-use applications include semiconductors, pharmaceuticals, high-performance fibers, specialty ceramics and epoxies as well as igniter formulations.

We operate two electrolytic and other chemical facilities in the United States: one in Hamilton, Mississippi producing sodium chlorate and one in Henderson, Nevada producing electrolytic manganese dioxide (“EMD”) and boron products.

Industry Background and Outlook

Titanium Feedstock Industry Background and Outlook

Titanium feedstock is considered to be a single product, although it can be segmented based on the level of titanium contained within the feedstock, with substantial overlap between each segment. Different grades of titanium feedstock have similar characteristics, and are generally suitable substitutes for one another; therefore, TiO₂ producers generally source a variety of feedstock grades, and supply a wide variety of feedstock grades to the TiO₂ producers.

Titanium minerals (ilmenite, rutile and leucoxene), titanium slag (chloride slag and sulphate slag) and synthetic rutile are all used primarily as feedstock for the production of TiO₂ pigment. According to the latest data provided by TZMI, approximately 90% of the world’s consumption of titanium feedstock is used for the production of TiO₂ pigment.

There are a small number of large mining companies or groups that are involved in the production of titanium feedstock. We believe we are the third largest titanium feedstock producer with approximately 10% of global titanium feedstock production. Rio Tinto, through its ownership of Canadian based Fer et Titane, its share in Richards Bay Minerals (“RBM”) in South Africa and ownership of QMM Madagascar, is the largest producer of titanium feedstock in the world. Australian-based Iluka Resources Limited is the second largest manufacturer, with operations in Australia and the United States. A number of other manufacturers, such as Cristal Global (Saudi Arabia), Eramet SA (France), Kenmare Resources plc (Ireland), Kronos Worldwide Inc. (Europe), Pangang Titanium Industry Co Ltd (China), Kerala Mines and Metals Limited (India) and Ostchem Holding AG (Eastern Europe) also supply titanium feedstock to the global market.

Beyond our structurally assured, relative low cost position, our competitive advantages are our depth of experience in various mining methods and technologies, our ability and know-how to produce upgraded products by means of direct current smelting of ilmenite and the synthetic rutile process, and our capacity to market zircon and rutile for use in a broad range of end-use applications. We are furthermore in a position to supply TiO₂ feedstock, zircon and high purity pig iron from any one of several production units in different geographical locations.

Although we use agents and distribution for some sales in the Asia-Pacific region, direct relationship marketing is the primary technique that we employ for the marketing of titanium feedstocks. Multi-year contracts are negotiated with periodic pricing for the pigment industry, while the contract period for other industries tends to be less than one year (either per shipment, quarterly, half-year or one year). Pricing for titanium feedstocks is usually adjusted either on a quarterly or half-year basis. In some instances, we use traders or agents for the sale of titanium feedstocks.

The geographic market for titanium feedstock is global in scope, and TiO₂ producers regularly source and transport titanium feedstock from suppliers located around the world.

Zircon Industry Background and Outlook

Zircon is extracted, alongside ilmenite and rutile, as part of the initial mineral sands beneficiation process. Zircon is a mineral which is primarily used as an additive in ceramic glazes to add hardness, which makes the ceramic glaze more water, chemical and abrasion resistant. It is also used for the production of zirconium and zirconium chemicals, in refractories, as a molding sand in foundries, and for TV glass, where it is noted for its structural stability at high temperatures and resistance to abrasive and corrosive conditions.

Zircon typically represents a relatively low proportion of heavy mineral sands mining but has high value compared to other heavy mineral products, resulting in it contributing a significant portion to total revenue. Refractories containing zircon are expensive and are only used in demanding, high-wear and corrosive

applications in the glass, steel and cement industries. Foundry applications use zircon when casting articles of high quality and value where accurate sizing is crucial, such as aerospace, automotive, medical and other high-end applications. Historically, zircon has constituted a relatively minor part of the total value produced as a result of the mining and processing of titanium minerals. However, from early 2000, zircon has increased in value as a co-product, although it remains dependent on the mining of titanium minerals for its supply.

Pigment Industry Background and Outlook

TiO₂ is used in a wide range of products due to its ability to impart whiteness, brightness and opacity, and is designed, marketed and sold based on specific end-use applications. TiO₂ is used extensively in the manufacture of paint and other coatings, plastics and paper and in a wide range of other applications, including inks, fibers, rubber, food, cosmetics and pharmaceuticals. According to TZMI data, the paint and coatings sector is the largest consumer of pigment averaging approximately 58% of total pigment consumption in 2011. The plastics sector accounted for approximately 22% of TiO₂ consumption in 2011, while the remaining 20% was divided between paper, inks, fibers and other.

TiO₂ is a critical component of everyday consumer applications due to its superior ability to cover or mask other materials effectively and efficiently relative to alternative white pigments and extenders. TiO₂ is considered to be a quality of life product and some research indicates that consumption generally increases as disposable income increases. We believe that, at present, TiO₂ has no effective mineral substitute because no other white pigment has the physical properties for achieving comparable opacity and brightness or can be incorporated in as cost-effective a manner.

According to the latest TZMI data, industry production capacity grew to 6.4 million tonnes from 6 million tonnes in the prior year. The global market in which our TiO₂ business operates is competitive. Competition is based on a number of factors such as price, product quality and service. We face competition from major international producers, including DuPont, Cristal Global, Huntsman, and Kronos, as well as smaller regional competitors such as Sachtleben Chemie GmbH and Ishihara Sangyo Kaisha, which operate multiple plants on single continents. We estimate that, based on nameplate capacity, these seven companies accounted for more than 64% of the global market share. During 2012, we had global TiO₂ production capacity of 465,000 tonnes per year, which was approximately 7% of global pigment capacity. In addition to the major competitors discussed above, we compete with numerous smaller, regional producers, including producers in China that have expanded their sulphate production capacity during the previous five years.

Worldwide, we believe that we and the other major producers mentioned above are the only companies that have perfected and successfully commercialized the chloride process technology for the production of TiO₂. According to TZMI, among the seven largest multi-national producers, 77% of available capacity uses the chloride process, compared to smaller producers who, on average, produce 6% of products using the chloride process, whileTiO₂ produced using chloride process technology is generally preferred for some TiO₂ end-use and specialty applications.

We have global operations with production facilities and a sales and marketing presence in the Americas, Europe and the Asia-Pacific regions. Our global presence enables us to sell our products to a diverse portfolio of customers with whom we have well-established relationships.

In recent years, demand growth has increased in Asia-Pacific, Central and Eastern Europe, the Middle East and Africa and South America more than in the mature economies of North America, Western Europe and Japan. Capacity growth over the next ten or so years is expected to be driven by the above global average demand growth in such emerging markets. While there are several chloride projects planned in China, it is unlikely that they will contribute any significant output before 2014. The probability of new greenfield projects (locations where there is not an existing infrastructure) is limited, given the limitations in feedstock supply, as well as

financial risks associated with the large investments in a facility, a long lead time and difficulty in achieving permitting (in particular, environmental permitting). As a result no significant new chloride TiO₂ facility has been built since 1994; however, over the years, the industry has increased capacity through expansion of existing plants and debottlenecking, and we expect this to continue going forward.

TiO₂ is produced using one of two commercial production processes: the chloride process and the sulphate process. The chloride process is a newer technology, and we believe it has several advantages over the sulphate process: it generates less waste, uses less energy, is less labor intensive and permits the direct recycle of chlorine, a major process chemical, back into the production process. The sulphate process can use lower quality (and therefore less expensive) feedstock. Commercial production of TiO₂ results in one of two different crystal forms, either rutile or anatase. Rutile TiO₂ is preferred over anatase TiO₂ for many of the largest end-use applications, such as coatings and plastics, because its higher refractive index imparts better hiding power at lower quantities than the anatase crystal form and it is more suitable for outdoor use because it is more durable. Although rutile TiO₂ can be produced using either the chloride process or the sulphate process, some customers prefer rutile produced using the chloride process because it typically has a bluer undertone and greater durability.

We are one of a limited number of TiO₂ producers in the world with chloride production technology. TiO₂ produced using the chloride process is preferred for some of the largest end-use applications. As a result of these advantages, the chloride process currently accounts for substantially all of the industry-wide TiO₂ production capacity in North America and approximately 50% of industry-wide capacity globally. All of our TiO₂ is produced using the chloride process.

Our Competitive Strengths

Leading Global Market Positions

We are among the world’s largest producers and marketers of TiO₂ products with approximately 7% of of global pigment capacity in 2012, and one of the world’s largest integrated TiO₂ producers. We are the third largest global producer and marketer of TiO₂ manufactured via chloride technology, which we believe is preferred for many applications compared to TiO₂ manufactured by other TiO₂ production technologies. We are the third largest titanium feedstock producer and a leader in global zircon production. Additionally, our fully integrated and global production facilities and sales and marketing presence in the Americas, Europe, Africa and the Asia-Pacific region enables us to provide customers in over 90 countries with a reliable supply of our products. The diversity of the geographic regions we serve increases our exposure to faster growing geographies, such as the Asia-Pacific region, and also mitigates our exposure to regional economic downturns because we can shift supply from weaker to stronger regions. We believe our relative size and vertical integration provides us with a competitive advantage in retaining existing customers and obtaining new business.

Well Positioned to Capitalize on Trends in the Feedstock and TiO₂ Industries

We believe the markets in which we participate have been, and will be, supply-constrained over the medium term. In the medium term, we anticipate no extended periods during which the supply of higher grade titanium feedstock and TiO₂ will exceed demand for each of these products. Because our production of titanium feedstock exceeds or required consumption, we believe that we will be well positioned to benefit from these market conditions.

Vertically Integrated Platform with Security of Titanium Feedstock Supply

As of March 31, 2013, our integration plan is on track to more fully demonstrate the material cost advantages it gives us. The vertical integration of titanium feedstock and TiO₂ production provides us with a secure and cost competitive supply of high grade titanium feedstock over the long-term. Our ability to supply all

of the feedstock that our pigment operations require enables us to balance our consumption and sales in ways that we believe our competitors cannot. During the first quarter of 2013, titanium feedstock sold internally to the pigment segment increased. As a result, during the first quarter of 2013, we cancelled contracts with two external ore suppliers.

Low Cost and Efficient Production Network

We believe our TiO₂ operations, and specifically our plant in Hamilton, Mississippi, are among the lowest cost producers of TiO₂ globally. This is of particular importance as it positions us to be competitive through all facets of the TiO₂ cycle. Moreover, our three TiO₂ production facilities are strategically positioned in key geographies. The Hamilton facility is the third largest TiO₂ production facility in the world and has the size and scale to service customers in North America and around the globe. Our plant in Kwinana, Australia is well positioned to service growing demand from Asia. Our Botlek facility in the Netherlands services our European customers and certain specialized applications globally. Combined with our titanium feedstock assets in South Africa and Australia, this network of TiO₂ and titanium feedstock facilities gives us the flexibility to optimize asset and feedstock utilization and generate operational, logistical and market efficiencies.

TiO₂ and Titanium Feedstock Production Technology

We are one of a limited number of TiO₂ producers in the world with chloride production technology. Our production capacity exclusively uses this process technology, which is the subject of numerous patents worldwide. Although we do not operate sulphate process plants and therefore cannot make a direct comparison, we believe the chloride production process generates less waste, uses less energy and is less labor intensive than the alternative sulphate process. Additionally, our titanium feedstock operations in South Africa and Australia are one of a limited number of feedstock producers with the expertise and technology to produce upgraded titanium feedstock (i.e., synthetic rutile and chloride slag) for use in the chloride process.

Innovative, High-Performance Products

We offer innovative, high-performance products for nearly every major TiO₂ end-use application. We seek to develop new products and enhance our current product portfolio to better serve our customers and respond to the increasingly stringent demands of their end-use sectors. Our new product development pipeline has yielded successful grade launches specifically targeting the plastics markets. In addition, we have completed mid-cycle improvement initiatives on our key coatings grades resulting in more robust products across a wide range of coatings formulations.

Experienced Management Team and Staff

The diversity of our management team’s business experience provides a broad array of skills that contributes to the successful execution of our business strategy. Our TiO₂ operations team and plant managers, who have manufacturing experience, participate in the development and execution of strategies that have resulted in production volume growth, production efficiency improvements and cost reductions. Our mineral sands operations team and plant managers have a deep reservoir of experience in mining, engineering and processing skills gained over many years in various geographies. Additionally, the experience, stability and leadership of our sales organization have been instrumental in growing sales, developing and expanding customer relationships.

Business Strategy

Our business strategy is to grow the company and to enhance our shareholder equity value by optimizing the beneficial effects of our present business attributes. We expect to implement this strategy through a disciplined

focus on cost reduction and operating efficiencies. We also plan to grow the business through a combined focus on the expanded production of our existing products and through strategic acquisitions and business partnerships in areas related to our industry to increase our standing in our global markets.

More specifically, our strategy includes the following components:

Maintain Operational Excellence

We are continually evaluating our business to identify opportunities to increase operational efficiency throughout our production network with a focus on maintaining operational excellence and maximizing asset efficiency. Our focus on enhancing operational excellence positions us to maximize yields, minimize operating costs and meet market growth over the short term without investing additional capital for capacity expansion. In addition, we intend to continue focusing on increasing manufacturing efficiencies through selected capital projects, process improvements and best practices in order to maximize yields, lower unit costs and improve our margins.

Leverage Our Low-Cost Production Network and Vertical Integration to Deliver Profitability and Cash Flow

We currently have TiO2 manufacturing facilities designed to produce approximately 465,000 tonnes of TiO2 annually. We expect that (assuming variable conversion costs per tonne remain constant or decline) increased production from this fixed cost base should increase margins and profitability. In addition, by assuring ourselves of the availability of the supply of titanium feedstock that these production facilities require, and by participating in the profitability of the mineral sands market directly, we have several different means of optimizing profitability and cash flow generation.

Ore In Use Optimization

We take advantage of the integrated nature and scale of the combined business, which provides the opportunity to capitalize on a wide range of titanium feedstock grades due to the ability to optimize internal ore usage and pursue external titanium feedstock end-markets that provide superior profit margins

Expand Global Leadership

We plan to continue to capitalize on our strong global market position to drive profitability and cash flow by enhancing existing customer relationships, providing high quality products and offering technical expertise to our customers. Furthermore, our vertically integrated global operations provide us with a solid platform for future growth in the TiO2, titanium feedstock, zircon and pig iron markets. Our broad product offering allows us to participate in a variety of end-use sectors and pursue those market segments that we believe have attractive growth prospects and profit margins. Our operations position us to participate in developing regions such as Asia, Eastern Europe and Latin America, which we expect to provide attractive growth opportunities. We will also seek to increase margins by focusing our sales efforts on those end-use segments and geographic areas that we believe offer the most attractive growth prospects and where we believe we can realize relatively higher selling prices over the long-term than in alternate sectors. We believe our global operations network, distribution infrastructure and technology will enable us to continue to pursue global growth.

Maintain Strong Customer Focus

We continue to target our key customer groups with innovative, high-performance products that provide enhanced value to our customers at competitive prices. A key component of our business strategy is to continually enhance our product portfolio with high-quality, market-driven product development. We design our

TiO2 products to satisfy our customers’ specific requirements for their end-use applications and align our business to respond quickly and efficiently to changes in market demands. We continue to execute on product improvement initiatives for our major coatings and plastics products. These improvement strategies will provide value in the form of better optical properties, stability, and durability to our customers. Further, new and enhanced grades are in the pipeline for 2013 and 2014.
