The Hope Downs mine is an iron ore mine located in the Pilbara region of Western Australia, 100 kilometres northwest of Newman.〔(MINEDEX website: Hope Downs search result ) accessed: 6 November 2010〕 The mine is partly owned and operated by Rio Tinto Iron Ore and is one of twelve iron ore mines the company operates in the Pilbara.〔(Pilbara ) Rio Tinto Iron Ore website, accessed: 6 November 2010〕〔(Mining ) Rio Tinto Iron Ore website, accessed: 6 November 2010〕 In the calendar year 2009, the combined Pilbara operations produced 202 million tonnes of iron ore, a 15 percent increase from 2008.〔(Preparing for the future ) Rio Tinto presentation, published: 23 March 2010, accessed: 7 November 2010〕 The Pilbara operations accounted for almost 13 percent of the world's 2009 iron ore production of 1.59 billion tonnes.〔(Global iron-ore production falls 6,2% in 2009 - Unctad report ) miningweekly.com, published: 30 July 2010, accessed: 7 November 2010〕〔(Production of iron ore fell in 2009, but shipments continued to increase, report says ) UNCTAD website, published: 30 July 2010, accessed: 7 November 2010〕 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.〔(Iron fact sheet - Australian Resources and Deposits ) Geoscience Australia website, accessed: 7 November 2010〕 The project leases are estimated to have 1,450 million tonnes of mineable ore and the mines to have an expected life of more than 30 years.〔(【引用サイトリンク】title=Hope Downs Iron Ore Project )〕 ==Overview== Rio Tinto iron ore operations in the Pilbara began in 1966.〔 Exploration work through Hancock Prospecting at Hope Downs deposit began in 1992. Hancock unsuccessfully tried to develop the project with a number of partners, briefly rumored to be planning to join up with the Fortescue Metals Group in 2005, who was then developing its Cloud Break mine in the region.〔(Hope Downs is still a one-mine track ) ''The Age'', published: 13 April 2005, accessed: 7 November 2010〕 The development of the project suffered further delays when attempts to gain access to BHP Billiton's rail network failed, burdening the project with a further A$1 billion in cost to construct rail and port infrastructure.〔''The Australian Mines Handbook - 2003-04 edition'', editor: Ross Louthean, publisher: Louthean Media Pty Ltd, page: 240〕 Eventually, in July 2005, Rio Tinto became a partner in the project instead, making thereby the construction of major infrastructure unnecessary, and, after spending A$1.3 billion, the mine moved into production in November 2007.〔(Hope Downs JV ) Hancock Prospecting website, accessed: 7 November 2010〕 The mine has an annual production capacity of 30 million tonnes of iron ore, sourced from open-pit operations. The ore is processed on site before being loaded onto rail.〔(Hope Downs mine ) Rio Tinto Iron Ore website, accessed: 6 November 2010〕 In the first half of 2009, Rio Tinto upgraded the mine from an annual production of 22 million tonnes to 30 million tonnes.〔(Western Australian Mineral and Petroleum Statistic Digest 2008-09 ) Department of Mines and Petroleum website, accessed: 8 November 2010〕 Ore from the mine is then transported to the coast through the Hamersley & Robe River railway, where it is loaded onto ships.〔(Rail ) Rio Tinto Iron Ore website, accessed: 6 November 2010〕 The 30 kilometre spur line connecting the mine with Rio Tinto's existing railway system was named "Lang Hancock Railway" in honor of Lang Hancock, founder of Hancock Prospecting and discoverer of the iron ore deposit.〔(Hope Downs deal sees wheel turn full circle ) ''The Age'', published: 5 July 2005, accessed: 7 November 2010〕 The mines workforce is on a Fly-in fly-out roster.〔 In the calendar year 2009, the mine employed 787 people, an increase in comparison to 2008, when it only employed 453.〔 Rio Tinto declared its intention to expand the mine, spending a further A$1.78 billion on its new Hope Downs 4 project, scheduled to produce 15 million tonnes of iron ore annually by 2013.〔(Rio Tinto to invest $1.78b in Hope Downs ) ''The Sydney Morning Herald'', published: 30 August 2010, accessed: 7 November 2010〕〔(Rio Tinto proceeds with Hope Downs iron project ) ''ABC Rural'', published: 31 August 2010, accessed: 7 November 2010〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hope Downs mine」の詳細全文を読む スポンサード リンク
