RIO TINTO

Overview

Rio Tinto is a diversified mining and metals company that produces materials used in infrastructure, transport, communications and decarbonisation-related supply chains. Its portfolio includes iron ore, aluminium, bauxite, alumina, copper, titanium dioxide, lithium, borates, salt and diamonds. The company states that its purpose is to be “finding better ways to provide the materials the world needs,” and says it aims to do so efficiently, effectively and sustainably while creating long-term value for stakeholders.[1]+3

The company has a broad international footprint, stating that it is active in 35 countries through mines and production facilities, exploration, and commercial, research, sales and corporate activities, and that the majority of its assets are located in OECD countries. Rio Tinto reported 2024 consolidated sales revenue of $53.7 billion and said it had about 60,000 employees worldwide, indicating a large-scale global operating base.[1]+4 [1]+7

Products & services

Rio Tinto’s disclosed product set is led by iron ore, with additional sales from aluminium, alumina and bauxite, copper, industrial minerals, gold, diamonds, and other products and freight services. In 2024, consolidated sales revenue by product was US$30.8 billion for iron ore (57.4% of total), US$13.0 billion for aluminium, alumina and bauxite (24.2%), US$4.7 billion for copper (8.8%), US$2.7 billion for industrial minerals including titanium dioxide slag, borates and salt (5.0%), US$0.8 billion for gold (1.5%), US$0.3 billion for diamonds (0.5%), and US$1.4 billion for other products and freight services (2.6%).[9][10]

More specifically, Rio Tinto discloses iron ore mining and iron ore pellets production at Iron Ore Company of Canada; titanium dioxide feedstock plus high-purity iron and steel production at Rio Tinto Fer et Titane; diamond mining and processing at Diavik; borates mining, refining and marketing at U.S. Borax; and copper mining, smelting and refining at Kennecott.[11] The industrial minerals revenue line specifically comprises titanium dioxide slag, borates and salt.[10] Rio Tinto also identifies lithium carbonate as an emerging product at Rincon, with planned system capacity of 60 kt per year of battery-grade lithium carbonate.[12]

On technical capabilities, Rio Tinto states that its Pilbara iron ore system has medium-term capacity of 345-360 million tonnes per year, and it notes flexibility to alter iron ore products’ technical specification as steelmaking demand changes.[13][14] In aluminium, the ELYSIS programme is scaling toward commercial-size smelting cells operating at 450kA, and the company is also developing hydrogen-based calcination at Yarwun.[15]+2 As a customer-facing service capability, Rio Tinto markets lower-carbon, responsibly sourced and traceable products and distributes them through a global logistics network; freight services are also reported as a separate revenue line.[18][10] [9]+9

Geographic presence

Rio Tinto’s operating footprint is centered on Australia, Canada, Mongolia and the United States, with additional operations and projects in Brazil, Argentina, Guinea, Madagascar, New Zealand, Singapore and South Africa. Its principal country exposures include iron ore and salt in Australia; diamonds, iron ore, aluminium and titanium dioxide feedstock in Canada; copper and gold in Mongolia; copper, borates and copper development/technology activities in the US; bauxite and alumina in Brazil; ilmenite in Madagascar; mineral sands and titanium dioxide-related products in South Africa; aluminium smelting in New Zealand; commercial activities in Singapore; and lithium development in Argentina. Rio Tinto states that the majority of its assets are located in OECD countries.[11][19]

Its asset base is weighted toward Australia and North America. In 2023, non-current assets other than excluded items were US$31.4 billion in Australia, US$15.4 billion in Canada, US$14.2 billion in Mongolia and US$7.2 billion in the United States, with additional concentrations in South America at US$3.6 billion and Africa at US$3.4 billion.[20]

Sales are more concentrated in Asia than the asset footprint. In 2024, 57.4% of consolidated sales revenue was destined for Greater China, 16.8% for the US, 6.9% for Asia excluding Greater China and Japan, 6.5% for Japan, 4.8% for Europe excluding the UK, 2.9% for Canada and 2.0% for Australia. Rio Tinto defines destination geographically by the ultimate country of destination where known, or otherwise by the customer shipping address.[21][22]

Rio Tinto is headquartered in London and has a corporate office in Melbourne; its registered offices are at 6 St James’s Square, London, and 120 Collins Street, Melbourne. The group also identifies a commercial hub in Singapore and services hubs in Brisbane, Perth and Montreal. On its website, Rio Tinto says it operates across 34 countries and 6 continents with 61,000+ employees, including more than 24,000 people in Australia and New Zealand and more than 20,000 people in Africa, the latter figure including contractors and joint venture partners.[23]+5 [11]+10

Business segments

Rio Tinto reports four principal operating segments under its product-group management structure: Iron Ore, Aluminium, Copper and Minerals, with performance assessed primarily using underlying EBITDA. The segment disclosures are presented as “financial information by business unit,” showing both the four reportable segments and their main operating units within each segment.[29]+2

Iron Ore is centered on Pilbara iron ore and Dampier Salt, and was by far the largest segment in FY2024, contributing about 51% of reportable segment revenue ($29.3bn of $57.8bn) and about 66% of underlying EBITDA ($16.2bn of $24.4bn). Aluminium covers bauxite, alumina, North American Aluminium and Pacific Aluminium, plus integrated operations, and contributed about 24% of revenue and 15% of underlying EBITDA. Copper includes Kennecott, Escondida and Oyu Tolgoi, contributing about 16% of revenue and 14% of underlying EBITDA. Minerals includes Iron Ore Company of Canada, Rio Tinto Iron & Titanium, Rio Tinto Borates and Diamonds, and contributed about 10% of revenue and 4% of underlying EBITDA.[32]+2

At a more detailed level, Rio Tinto’s segment notes show the internal composition of each segment rather than a second, separate official segmentation: Iron Ore is mainly Pilbara; Aluminium is split across bauxite, alumina and primary aluminium businesses; Copper is anchored by Kennecott, Escondida and Oyu Tolgoi; and Minerals groups a broader set of specialty mining assets including IOC, titanium feedstocks, borates and diamonds.[31] [29]+4

Company history

Rio Tinto traces its origins to the Rio Tinto mines in Spain, where the Rio Tinto Company was incorporated in 1873 to reopen ancient copper workings. The business later expanded beyond Spain, including exploration in what is now Zambia from 1929. In Australia, Rio Tinto Limited was incorporated in 1959, and in 1962 the Australian interests of The Consolidated Zinc Corporation and The Rio Tinto Company were merged to form Conzinc Riotinto of Australia (CRA), which was renamed CRA Limited in 1980.[34]+2

Mid-20th-century discoveries and developments helped shape the group’s modern asset base, including the 1955 discovery of bauxite at Weipa, the start of commercial bauxite mining there in 1963, and the first Pilbara iron ore shipment to Japan in 1966. The modern corporate structure was created in 1995, when RTZ and CRA were merged contractually through a dual-listed companies structure under a common board; in 1997, RTZ became Rio Tinto plc and CRA became Rio Tinto Limited.[37]+3

Rio Tinto continued to expand through major acquisitions, including North Ltd in 2000. In 2007, it completed the takeover of Alcan, a transaction that significantly enlarged its aluminium business and made it a global leader in that sector.[41]+2 [34]+9
