br /> Rio Tinto's Pilbara iron ore operations include 11 mines, three shipping terminals and a privately owned heavy freight rail network. The operations in the Pilbara began in 1966, at the Mount Tom Price mine, and currently have an annual capacity of 220 million tonnes In the Pilbara, Rio Tinto owns all of Hamersley Iron's six mines, Brockman, Nammuldi, Mount Tom Price, Marandoo, Paraburdoo and Yandicoogina, as well as operates the Channar mine (60 per cent), the Hope Downs mine (50:50 joint venture with Hancock Prospecting Pty Ltd) and the Eastern Range mine (54 per cent). Rio Tinto also has a 53 per cent operating interest in the West Angelas and Mesa J mines, owned by Robe River Iron Associates 
Rail and Ports
The rail system is a vital part of Rio Tinto's iron ore operations. The rail system services all 11 mines and transports ore to Rio Tinto's two ports, Dampier (100 per cent ownership) and Cape Lambert (53 per cent joint venture with Robe River).Advanced on board computers allow for a single man operation with the train control centre located in Perth. 
Mining and Processing
All of Rio Tinto's Pilbara operations use open pit mining methods. All the operations also contain on-site processing facilities. Ore from Eastern Range and Channar is partly processed on site with the secondary crushed material being sent to Paraburdoo processing plant via a conveyor belt for further processing. A range of different processing techniques are used at the 11 mines, ranging from conventional crushing and screening, to ore beneficiation processes to improve the ore quality .
Products
There are a number of different ore types that are produced by Rio Tinto's Pilbara operations. The Mesa J mine produces Robe River Lump and Fines, which is transported by rail to the port at Cape Lambert and exported into Japan, Europe and Asia). The Yandicoogina mine produces Hamersley Iron Yandicoogina Fines (HIY � F), with the rest of Rio Tinto's mines contributing to form Pilbara Blend Lump and Fines. Ore from the Hamersley Iron operations is transported by rail to the port of Dampier and is exported to supply the European and Pacific Rim steel industries
