The exploration of the ore deposits began in 1988 by Somincor. In June 2004, Somincor, which owns the mine, was acquired by EuroZinc from Empresa de Desenvolvimento Mineiro and Rio Tinto . In October 2006, EuroZinc was acquired by Lundin Mining . In May 2017, Lundin Mining announced an expansion project for

156-521: A CAU (Contact, Agreement or Understanding). Typologies have emerged to distinguish distinct forms of cartels: A survey of hundreds of published economic studies and legal decisions of antitrust authorities found that the median price increase achieved by cartels in the last 200 years is about 23 percent. Private international cartels (those with participants from two or more nations) had an average price increase of 28 percent, whereas domestic cartels averaged 18 percent. Less than 10 percent of all cartels in

234-413: A behavioural approach is often used to identify behavioural collusive patterns, to initiate further economic analysis into identifying and prosecuting those involved in the operations. For example, studies have shown that industries are more likely to experience collusion where there are fewer firms, products are homogeneous and there is a stable demand. Leniency programmes were first introduced in 1978 in

312-614: A key factor in recommending the transaction to its shareholders. In March 2010, it was announced that Chinalco would invest $ 1.3 billion for a 44.65% stake in Rio Tinto's iron ore project in Simandou , Guinea. Rio Tinto retained 50.35% ownership at Simandou. In November 2011, Rio joined with Chinalco to explore for copper resources in China's complex landscape, by setting up a new company, CRTX, 51% owned by Chinalco and 49% by Rio Tinto. Under

390-553: A larger impact in World War II. Because cartels are likely to have an impact on market positions, they are subjected to competition law , which is executed by governmental competition regulators . Very similar regulations apply to corporate mergers . A single entity that holds a monopoly is not considered a cartel but can be sanctioned through other abuses of its monopoly. Prior to World War II, members of cartels could sign contracts that were enforceable in courts of law except in

468-419: A leniency program: The application of leniency programme penalties varies according to individual countries policies and are proportional to cartel profits and years of infringement. However, typically the first corporation or individual to cooperate will receive the most reduced penalty in comparison to those who come forward later. The effectiveness of leniency programmes in destabilising and deterring cartels

In 1993, the company acquired Nerco and the United States coal mining businesses of Cordero Mining Company . In 2000, Rio Tinto acquired North Limited , an Australian company with iron ore and uranium mines, for $ 2.8 billion. The takeover

624-556: A memorandum of understanding to develop Rio Tinto's iron ore project in the Simandou mine in Simandou , Guinea . On 29 July 2010, Rio Tinto and Chinalco signed a binding agreement to establish this joint venture covering the development and operation of the Simandou mine. Under the terms of the agreement, the joint venture maintains Rio Tinto's 95% interest in the Simandou project as follows: By providing US$ 1.35 billion on an earn-in basis through sole funding of ongoing development over

702-481: A syndicate consisting of Deutsche Bank (56% ownership), Matheson (24%) and the civil engineering firm Clark, Punchard and Company (20%). At an auction held by the Spanish government to sell the mine on 14 February 1873, the group won with a bid of £ 3.68 million ( ESP 92.8 million). The bid also specified that Spain would permanently relinquish any right to claim royalties on the mine's production. Following purchase of

780-435: A transition phase in which prices tend to rise, and end with a stationary phase in which price variance remains low. Indicators such as price changes alongside import rates, market concentration, time period of permanent price changes and stability of companies' market shares are used as economic markers to help supplement the search for cartel behaviour. On the contrary, when aiming to create suspicion around potential cartels,

858-550: A two-to-three-year period, Chalco, a subsidiary of Chinalco, would acquire a 47% interest in the joint venture. Once the full sum was paid, Rio Tinto would be left with a 50.35% interest in the project and Chalco would have 44.65%. The remaining 5% would be owned by the International Finance Corporation (IFC), the financing arm of the World Bank . On 22 April 2011 Rio Tinto, its subsidiary Simfer S.A. (Simfer), and

Rio Tinto is primarily organised into four operational businesses, divided by product type: These operating groups are supported by separate divisions providing exploration and function support. Rio Tinto is structured as a dual-listed company , with listings on both

1092-442: Is wholly owned. Operations typically include mining of ore through to production of 99.99% purified copper, including extraction of economically valuable by-products . Together, Rio Tinto's share of copper production at its mines totalled nearly 700,000 tonnes , making the company the fourth-largest copper producer in the world. Rio Tinto Copper continues to seek new opportunities for expansion, with major exploration activities at

1170-480: The Australian Competition & Consumer Commission . The largest barrier to completing the investment may come from Rio Tinto's shareholders; support for the deal by shareholders was never overwhelming and has reportedly declined in 2009, as other financing options (such as a more traditional bond issuance) are beginning to appear more realistic as a viable alternative funding source. A shareholder vote on

The dual-listed company structure grants shareholders of the two companies the same proportional economic interests and ownership rights in the consolidated Rio Tinto, in such a way as to be equivalent to all shareholders of

1404-504: The London Stock Exchange , where it is a component of the FTSE 100 Index , and the Australian Securities Exchange , where it is a component of the S&P/ASX 200 index. American depositary shares of Rio Tinto's British branch are also traded on the New York Stock Exchange , giving it listings on three major stock exchanges. In the 2020 Forbes Global 2000 , it was ranked the world's 114th-largest public company. Rio Tinto has faced widely criticism by environmental groups as well as

1482-611: The Pilbara , Western Australia. The Pilbara iron ore operations include 16 iron ore mines, four independent port terminals, a 1,700-kilometre rail network and related infrastructure. The corporation also has had a majority stake in Iron Ore Company of Canada since its 2000 hostile takeover of North Limited. Copper was one of Rio Tinto's main products from its earliest days operating at the Rio Tinto complex of mines in Spain. Since that time,

1560-514: The Resolution Copper project in the United States, Winu in Australia, and Oyu Tolgoi underground mine in Mongolia. In addition, the company is seeking to become a major producer of nickel, with exploration projects currently underway in the United States and Indonesia. Although not the primary focus of Rio Tinto Copper's operations, several economically valuable by-products are produced during

1638-561: The Rio Tinto , in Huelva , Spain, from the Spanish government. It has grown through a long series of mergers and acquisitions. Although primarily focused on extraction of minerals, it also has significant operations in refining, particularly the refining of bauxite and iron ore. It has joint head offices in London , England and Melbourne , Australia. Rio Tinto is a dual-listed company traded on both

1716-464: The Spanish Civil War , World War II and Franco's nationalistic policies . In the 1950s, the political situation made it increasingly difficult for mostly British and French owners to extract profits from Spanish operations, and the company decided to dispose of the mines from which it took its name. Thus, in 1954, Rio Tinto Company sold two-thirds of its stake in the Rio Tinto mines, disposing of

1794-480: The government of Norway for the environmental impacts of its mining activities. Since antiquity, a site along the Rio Tinto in Huelva , Spain, has been mined for copper, silver, gold and other minerals. Around 3000 BC, Iberians and Tartessians began mining the site, followed by the Phoenicians , Greeks , Romans , Visigoths and Moors . After a period of abandonment, the mines were rediscovered in 1556 and

1872-419: The price of oil . Drawing upon research on organizational misconduct, scholars in economics, sociology and management have studied the organization of cartels. They have paid attention to the way cartel participants work together to conceal their activities from antitrust authorities. Even more than reaching efficiency, participating firms need to ensure that their collective secret is maintained. “However,

Westinghouse filed an antitrust lawsuit against cartel members in 1976 and the cartel disbanded. Like many major mining companies, Rio Tinto has historically grown through a series of mergers and acquisitions. The company's first major acquisition occurred in 1929, when the company issued stock for

2028-435: The $ 16 billion Canadian group's " poison pill " defence was not valid. Ivanhoe had developed Oyu Tolgoi in Mongolia, one of the world's largest-known copper deposits. On 28 January 2012, Rio Tinto gained control of Ivanhoe Mines and removed the management. In October 2013, Rio Tinto agreed to sell its majority stake in Australia's third-largest coal mine to Glencore and Sumitomo for a little over US$ 1 billion, as part of

2106-526: The 18th and 19th centuries. Around 1870, cartels first appeared in industries formerly under free-market conditions. Although cartels existed in all economically developed countries, the core area of cartel activities was in central Europe. The German Empire and Austria-Hungary were nicknamed the "lands of the cartels". Cartels were also widespread in the United States during the period of robber barons and industrial trusts . The creation of cartels increased globally after World War I . They became

2184-628: The Australian coal businesses of the Peabody Energy . On 14 November 2007, Rio Tinto completed its largest acquisition to date, purchasing Canadian aluminium company Alcan for $ 38.1 billion, as of 2014 , "the largest mining deal ever completed". Alcan's chief executive, Jacynthe Côté, led the new division, renamed Rio Tinto Alcan with its headquarters situated in Montreal . Activity in 2008 and 2009

2262-460: The Australian firm Consolidated Zinc to form the Rio Tinto – Zinc Corporation (RTZ) and its main subsidiary, Conzinc Riotinto of Australia (CRA). The merger provided Rio Tinto the ability to exploit its new-found opportunities, and gave Consolidated Zinc a much larger asset base. RTZ and CRA were separately managed and operated, with CRA focusing on opportunities within Australasia and RTZ taking

2340-600: The Guinean Government signed a settlement agreement that secured Rio Tinto's mining rights in Guinea to the southern concession of Simandou, known as blocks 3 and 4. According to the agreement, Simfer would pay US$ 700 million and receive mining concession and government approval of the proposed Chalco and Rio Tinto Simandou joint venture. In April 2011, Rio Tinto gained a majority stake in Riversdale Mining . In 2011,

2418-561: The Italian word cartello , which means a "leaf of paper" or "placard", and is itself derived from the Latin charta meaning "card". The Italian word became cartel in Middle French , which was borrowed into English. In English, the word was originally used for a written agreement between warring nations to regulate the treatment and exchange of prisoners from the 1690s onward. From 1899 onwards,

2496-489: The Rio Tinto Mine was the world's leading producer of copper. From 1870 through 1925, the company was inwardly focused on fully exploiting the Rio Tinto Mine, with little attention paid to expansion or exploration activities outside of Spain. The company enjoyed strong financial success until 1914, colluding with other pyrite producers to control market prices. However, World War I and its aftermath effectively eliminated

2574-428: The Spanish government began operating them once again in 1724. However, Spain's mining operations there were inefficient, and the government itself was otherwise distracted by political and financial crises, leading the government to sell the mines in 1873 at a price later determined to be well below actual value. The purchasers of the mine were led by Hugh Matheson 's Matheson & Company , which ultimately formed

The company's failure to diversify during this period led to the slow decline of the company among the ranks of international mining firms. However, this changed in 1925, when Sir Auckland Geddes succeeded Lord Alfred Milner as chairman. Geddes and the new management team he installed focused on diversification of

2886-476: The United States strictly turned away from cartels. After 1945, American-promoted market liberalism led to a worldwide cartel ban, where cartels continue to be obstructed in an increasing number of countries and circumstances. Cartels have many structures and functions that ideally enable corporations to navigate and control market uncertainties and gain collusive profits within their industry. A typical cartel often requires what competition authorities refer to as

2964-768: The United States. Before 1945, cartels were tolerated in Europe and specifically promoted as a business practice in German-speaking countries. In U.S. v. National Lead Co. et al. , the Supreme Court of the United States noted the testimony of individuals who cited that a cartel, in its versatile form, is a combination of producers for the purpose of regulating production and, frequently, prices, and an association by agreement of companies or sections of companies having common interests so as to prevent extreme or unfair competition. The first legislation against cartels to be enforced

Stern Hu was also accused of bribery by Chinese steel mill executives for sensitive information during the iron ore contract negotiations. On 19 March 2010 Rio Tinto and its biggest shareholder, Chinalco , signed

3120-549: The breakdown of the cooperation needed to sustain the cartel. Cartels are usually associations in the same sphere of business, and thus an alliance of rivals. Most jurisdictions consider it anti-competitive behavior and have outlawed such practices. Cartel behavior includes price fixing , bid rigging, and reductions in output. The doctrine in economics that analyzes cartels is cartel theory . Cartels are distinguished from other forms of collusion or anti-competitive organization such as corporate mergers . The word cartel comes from

3198-519: The company has divested itself from its original Spanish mines, and grown its copper-mining capacity through acquisitions of major copper resources around the world. The copper group's main active mining interests are Oyu Tolgoi mine in Mongolia, Kennecott Utah Copper in the United States, and Minera Escondida in Chile. Most of these mines are joint ventures with other major mining companies, with Rio Tinto's ownership ranging from 30% to 80%; only Kennecott

Rio Tinto also performs processing on some of these materials, with plants dedicated to processing bauxite into alumina and aluminium, and smelting iron ore into iron. The company also produces other metals and minerals as by-products from

3354-558: The company rekindled its interest in potash when it entered a joint venture with Acron Group to develop the Albany potash development, in southern Saskatchewan , Canada. Following an exploration program, Acron in a June 2014 statement described Albany as "one of the best potash development opportunities in the world". On 13 December 2011, an independent arbitrator cleared the way for Rio Tinto, which had owned 49% of Ivanhoe Mines (now known as Turquoise Hill Resources ), to take it over: he said

3432-456: The company's dual-listed company structure, management powers of the Rio Tinto are consolidated in a single senior management group led by a board of directors and executive committee. The board of directors has both executive and non-executive members, while the executive committee is composed of the heads of major operational groups. Rio Tinto engages professional lobbyists to represent its interests in various jurisdictions. In South Australia,

3510-498: The company's investment strategy and the introduction of organisational and marketing reforms. Geddes led the company into a series of joint ventures with customers in the development of new technologies, as well as exploration and development of new mines outside of Spain. Between 1925 and 1931, Geddes recruited two directors: JN Buchanan (finance director) and RM Preston (commercial director), as well as other executives involved with technical and other matters. Perhaps most significant

3588-453: The economy. At the same time, American lawyers increasingly turned against trade restrictions , including all cartels. The Sherman act , which impeded the formation and activities of cartels, was passed in the United States in 1890. The American viewpoint, supported by activists like Thurman Arnold and Harley M. Kilgore , eventually prevailed when governmental policy in Washington could have

3666-491: The firm's plans to focus on larger operations. Less than a year later, Rio Tinto rejected two merger proposals from Glencore, proffered in July and August 2014; the merger of Glencore and Rio Tinto would have created the world's largest mining company. In May 2015, Rio Tinto announced plans to sell some of its aluminium assets as part of a possible $ 1 billion deal, two years after a similar but failed attempt. In September 2020, it

3744-415: The incentives to form a new cartel return, and the cartel may be re-formed. Publicly known cartels that do not follow this business cycle include, by some accounts, OPEC. Cartels often practice price fixing internationally. When the agreement to control prices is sanctioned by a multilateral treaty or protected by national sovereignty, no antitrust actions may be initiated. OPEC countries partially control

3822-475: The leading form of market organization , particularly in Europe and Japan. In the 1930s, authoritarian regimes such as Nazi Germany , Italy under Mussolini , and Spain under Franco used cartels to organize their corporatist economies . Between the late 19th century and around 1945, the United States was ambivalent about cartels and trusts. There were periods of both opposition to market concentration and relative tolerance of cartels. During World War II ,

3900-455: The market. A cartel is an organization formed by producers to limit competition and increase prices by creating artificial shortages through low production quotas, stockpiling , and marketing quotas. Cartels can be vertical or horizontal but are inherently unstable due to the temptation to defect and falling prices for all members. Additionally, advancements in technology or the emergence of substitutes may undermine cartel pricing power, leading to

3978-402: The mean duration of discovered cartels is from 5 to 8 years and overcharged by approximately 32%. This distribution was found to be bimodal, with many cartels breaking up quickly (less than a year), many others lasting between five and ten years, and still some that lasted decades. Within the industries that have operating cartels, the median number of cartel members is 8. Once a cartel is broken,

At the end of the 1880s, control of the firm passed to the Rothschild family , who increased the scale of its mining operations. Following their purchase of the Rio Tinto Mine, the new ownership constructed a number of new processing facilities, innovated new mining techniques, and expanded mining activities. From 1877 to 1891,

Rio Tinto (corporation) Rio Tinto Group is a British-Australian multinational company that is the world's second largest metals and mining corporation (behind BHP ). It was founded in 1873 when a group of investors purchased a mine complex on

4212-510: The orchestrator, often the vendor with all information, typically remains unnoticed by antitrust authorities, raising questions about the culpability of unaware distributors.” The scientific analysis of cartels is based on cartel theory . It was pioneered in 1883 by the Austrian economist Friedrich Kleinwächter and in its early stages was developed mainly by German-speaking scholars. These scholars tended to regard cartels as an acceptable part of

4290-546: The processing of its main resources, including gold, silver, molybdenum , sulphuric acid , nickel, potash , lead and zinc . Rio Tinto controls gross assets of $ 81 billion in value across the globe, with main concentrations in Australia (35%), Canada (34%), Europe (13%) and the United States (11%), and smaller holdings in South America (3%), Africa (3%) and Indonesia (1%). The Australian operations of Rio Tinto Iron Ore (RTIO) comprises an integrated iron ore operations in

4368-502: The proposed deal was expected in the third quarter of 2009. Rio Tinto is believed to have pursued this combined asset and convertible bond sale to raise cash to satisfy its debt obligations, which required payments of $ 9.0 billion in October 2009 and $ 10.5 billion by the end of 2010. The company has also noted China's increasing appetite for commodities, and the potential for increased opportunities to exploit these market trends, as

4446-430: The purchase of ownership interests of Rio Tinto assets in its iron ore, copper and aluminium operations, plus $ 7.2 billion for convertible bonds . The transaction would bring Chinalco's ownership of the company to roughly 18.5%. The deal is still pending approval from regulators in the United States and China, and has not yet been approved by shareholders, although regulatory approval has been received from Germany and

4524-619: The purpose of raising 2.5 million pounds to invest in Northern Rhodesian copper mining companies, which was fully invested by the end of 1930. The Rio Tinto company consolidated its holdings of these various firms under the Rhokana Corporation by forcing the various companies to merge. Rio Tinto's investment in Rhodesian copper mines did much to support the company through troubled times at its Spanish Rio Tinto operations spanning

4602-529: The refining of copper ore into purified copper. Gold, silver, molybdenum and sulphuric acid are all removed from copper ore during processing. Due to the scale of Rio Tinto's copper mining and processing facilities, the company is also a leading producer of these materials, which drive substantial revenues to the company. Cartel A cartel is a group of independent market participants who collude with each other as well as agreeing not to compete with each other in order to improve their profits and dominate

4680-411: The rest of the world. However, the companies continued to trade separately, and RTZ's ownership of CRA dipped below 50% by 1986. The two companies' strategic needs eventually led to conflicts of interest regarding new mining opportunities, and shareholders of both companies determined a merger was in their mutual best interest. In 1995, the companies merged into a dual listed company , in which management

4758-451: The rest over the following years. The sale of the mines financed extensive exploration activities over the following decade. The company's exploration activities presented the company with an abundance of opportunities, but it lacked sufficient capital and operating revenue to exploit those opportunities. This situation precipitated the next, and perhaps most significant, merger in the company's history. In 1962, Rio Tinto Company merged with

Tightly organized sales cartels existed in the mining industry of the late Middle Ages, like the 1301 salt syndicate in France and Naples , or the Alaun cartel of 1470 between the Papal State and Naples. Both unions had common sales organizations for overall production called the Societas Communis Vendicionis ('Common Sales Society'). Laissez-faire (liberal) economic conditions dominated Europe and North America in

4914-480: The sample failed to raise market prices. In general, cartel agreements are economically unstable in that there is an incentive for members to cheat by selling at below the cartel's agreed price or selling more than the cartel's production quotas. Many cartels that attempt to set product prices are unsuccessful in the long term because of cheating punishment mechanisms such as price wars or financial punishment. An empirical study of 20th-century cartels determined that

4992-418: The trade or commerce among the several States, or with foreign nations, shall be deemed guilty of a felony, and, on conviction thereof, shall be punished by fine not exceeding $ 100 million if a corporation, or, if any other person, $ 1 million, or by imprisonment not exceeding ten years, or by both said punishments, in the discretion of the court. In practice, detecting and desisting cartels is undertaken through

5070-427: The two companies actually being shareholders in a single, unified entity. This structure was implemented to avoid adverse tax consequences and regulatory burdens. To eliminate currency exchange issues, the company's accounts are kept, and dividends paid, in United States dollars. Rio Tinto is one of the largest companies listed on either exchange. As such, it is included in the widely quoted indices for each market:

5148-619: The usage of the word became generalized as to mean any intergovernmental agreement between rival nations. The use of the English word cartel to describe an economic group rather than international agreements was derived much later in the 1800s from the German Kartell , which also has its origins in the French cartel . It was first used between German railway companies in 1846 to describe tariff- and technical standardization efforts. The first time

5226-414: The use of economic analysis and leniency programmes. Economic analysis is implemented to identify any discrepancies in market behaviour between both suspected and unsuspected cartel engaged firms. A structural approach is done in the form of screening already suspicious firms for industry traits of a typical cartel price path. A typical path often includes a formation phase in which prices decline, followed by

In October 2024, Rio Tinto signed an agreement to acquire U.S.-based Arcadium Lithium for $ 6.7 billion. The deal involved a cash offer of $ 5.85 per share, reflecting a nearly 90% premium over Arcadium's recent closing price. The acquisition, expected to close in mid-2025, would integrate Arcadium's lithium assets into Rio's operations, further enhancing its portfolio of critical minerals. The company has operations on six continents, but

5538-587: Was announced that the company's chief executive Jean-Sébastien Jacques , along with two executives, would resign because of Rio Tinto's destruction of two ancient rock shelters in the Pilbara region of Australia. The company's chief financial officer, Jakob Stausholm , became the new chief executive on 1 January 2021. In March 2022, Rio Tinto completed the acquisition of Rincon Mining's lithium project in Argentina for $ 825 million, following approval by Australia's Foreign Investment Review Board .
