Iron ore mining in Western Australia has grown into a massive industry over the last fifty years. In 2017, Western Australia was the largest iron ore producer in the world, accounting for about 98% of Australia's Economic Demonstrated Resources (EDR) of the metal, which is around 28 billion tonnes. The major iron ore producers in Western Australia include BHP Billiton, Rio Tinto, Fortescue Metals Group (FMG), and Roy Hill. There are at least 63 iron ore mines in Australia, according to GlobalData's mines and projects database, with 18 mines in the Pilbara region alone.

Iron ore exports
Iron ore mining in Western Australia has been a major industry and export for the state, dating back to the late 1890s. While the Pilbara iron ore deposits were known, it was not until 1960 that mining began in earnest when the Australian government lifted the embargo on iron ore exports. Up until the mid-1960s, iron ore production in Western Australia was negligible, at less than 10 million tons per year. In 1960, Australia shipped 500 tons of iron ore overseas; in 2013, this number had grown to 300 million tons.
Western Australia is home to numerous iron ore mines, with the Pilbara region being the biggest producer, accounting for over 92% of Australia's iron ore output. The first mine in the Pilbara, the Goldsworthy mine, was developed in 1965 by Mount Goldsworthy Mining Associates, a joint venture between British-owned Consolidated Goldfields (Aust) Pty Ltd, Cyprus Mines Corporation of Los Angeles, and the Utah Construction & Mining Company of San Francisco.
The two biggest producers, Rio Tinto and BHP, accounted for 90% of all iron ore production in the state in 2008-09. Rio Tinto operates twelve iron ore mines in Western Australia, while BHP operates seven. Both companies have expanded their output over the years, with Rio Tinto reporting a 2% production growth in 2018 and BHP reporting a 3% increase in production from the previous year.
Australia plays a critical role in the global iron ore supply chain, with a significant portion of its iron ore exported for overseas consumption. In 2023, the value of iron ore exported from Australia to China amounted to around 115 billion Australian dollars, making China the leading export destination for Australian iron ore. Japan, South Korea, and Taiwan are also major importers of Australian iron ore products.
The export of iron ore has had significant impacts on Western Australia. The mining boom in the early 2000s led to an influx of workers, increased land prices, and negatively impacted tourism due to limited accommodation. Additionally, the development of mines and port facilities at Finucane Island, Port Hedland has resulted in the construction of infrastructure such as the Goldsworthy railway.

Rio Tinto operations
Rio Tinto is one of the world's leading producers of iron ore. Its iron ore operations in the Pilbara region of Western Australia comprise a network of 17 iron ore mines, four independent port terminals, and a 1,900-kilometre rail network. Rio Tinto's operations in the Pilbara began in 1966 with the opening of the Mount Tom Price mine, which was the company's first mine in the region. The company operates 12 iron ore mines in Western Australia, all located in the Pilbara region.
Rio Tinto's iron ore mines in Western Australia include the Greater Tom Price Mine, a surface mine that produced an estimated 51.62 million tonnes per annum (mtpa) of iron ore in 2023 and is expected to operate until 2035. The company's other mines in the region include the Brockman 4 mine, which is being expanded to produce 40 million tonnes of iron ore per annum, and the Western Turner Syncline project, which is expected to produce 15 million tonnes per annum. Rio Tinto also operates the Hamersley and Robe River railway lines, which transport iron ore from the company's mines to the ports of Cape Lambert and Dampier.
Rio Tinto's operations in Western Australia include the use of advanced technology such as autonomous trucks, trains, plants, and drills. The company's $2.6 billion Gudai-Darri iron ore project is its most technologically advanced mine, featuring over 70 design innovations. Rio Tinto also utilizes a "digital asset," a digital replica of the mine site that combines data from processing plants and historical design information to optimize plant operations. The company's AutoHaul™ system, its first driverless heavy-haul, long-distance train, improves safety and cycle times by using automated responses to speed restrictions and alarms.
Rio Tinto's iron ore operations in Western Australia have contributed to the state's iron ore production boom since the early 2000s. The company, along with BHP, accounted for 90% of all iron ore production in Western Australia during the 2008-2009 financial year. Rio Tinto's expansion projects, such as the Hope Downs 4 project, aim to further increase production capacity. The company's operations have had social and economic impacts on the Pilbara region, including an influx of workers, rising land prices, and increased employment opportunities for Indigenous Australians.
