The McArthur River Uranium Mine, in northern Saskatchewan, Canada, is the world's largest high-grade uranium deposit. The McArthur River deposit was discovered in 1988. The property is located 620 air kilometres north of Saskatoon, Saskatchewan and 80 kilometres northeast of the Key Lake mill in the uranium rich Athabasca Basin. Mine construction began in 1997, with production commencing in 1999. The mine achieved full commercial production in November 2000. Production is regulated at 18.7 million pounds of yellowcake a year with the ore being processed through the Key Lake mill. Between 2000 and 2013, the McArthur River/Key Lake operation has produced 250.6 million pounds U3O8.〔(【引用サイトリンク】url=http://www.cameco.com/mining/mcarthur_river/ )〕 In 2012, McArthur River was the world's largest producing uranium mine, accounting for 13% of world mine production. (Canada, as a whole, produces 15% of the world's uranium production.) __NOTOC__ ==Reserves== As of December 31, 2013, the mine has proven and probable reserves of 1,037,400 tonnes at an average grade of 15.76% U3O8.〔(【引用サイトリンク】url=http://www.cameco.com/annual_report/2013/mda/mineral-reserves-resources/reserves/ )〕 (360.5 Million pounds) 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「McArthur River uranium mine」の詳細全文を読む スポンサード リンク
