The mine is owned by Robe River Iron Associates (53% Rio Tinto) and operated by Rio Tinto Iron Ore and is one of twelve iron ore mines the company operates in the Pilbara.[2][3] In the calendar year 2009, the combined Pilbara operations produced 202 million tonnes of iron ore, a 15 percent increase from 2008.[4] The Pilbara operations accounted for almost 13 percent of the world's 2009 iron ore production of 1.59 billion tonnes.[5][6]

The Hamersley Range, where the mine is located, contains 80 percent of all identified iron ore reserves in Australia and is one of the world's major iron ore provinces.[7]

Overview
Iron ore mines in the Pilbara region.

Rio Tinto's iron ore operations in the Pilbara began in 1966.[2] The mine itself began operations in 2002. The mine has an annual production capacity of 29.5 million tonnes of iron ore, sourced from open-pit operations. The ore is processed on site before being loaded onto rail.[8]

Ore from the mine is then transported to the coast through the Hamersley & Robe River railway, where it is loaded onto ships.[9] Ore from West Angelas, like from Mesa J, is taken to Cape Lambert by rail to be exported as fines. The fines have a maximum size of 9.5 mm.[10]

The mine's workforce is on a fly-in fly-out roster.[8] In the calendar year 2009, the mine employed 989 people, an increase in comparison to 2008, when it only employed 867.[11]

West Angelas is the site of Rio Tinto's "Mine of the future" project. The mine operates automated trucks, automated rockbreakers, automated drills and blasts, which are controlled from a Perth operations centre rather than local operators on site.[12]

Robe River Iron Associates

Robe River Iron, owner of the mine, is jointly owned by the following companies:[1]

Robe River Iron operates the West Angelas, Mesa A and Mesa J mines.[11] Rio Tinto acquired its share of 53% in late 2000, when it took over mining company North Limitd.[13]

gollark: The MPU6050 has an accelerometer + gyroscope for that, and I think it has *some* way to give you absolute orientation data through something.
gollark: And there's no way to get it to get absolute orientation using the magnetometer data too?
gollark: How would you not be able to get that if you used the magnetometer + MPU6050?
gollark: It should probably be fine.
gollark: Oh, I used one of those for a thing, the drift was fine and the magnetometer probably lets you compensate for it.
