According to the United States Geological Survey, Vietnam is estimated to hold the world's third-largest bauxite ore reserves, after Guinea and Australia.〔 The majority of Vietnam's reserves are located in the Central Highlands (Tây Nguyên) and have only been minimally mined. Bauxite is typically strip mined and is used to produce aluminum. According to estimates by Vietnam's Ministry of Industry and Trade, Vietnam's reserves in the Central Highlands amount to 5.4 billion tons.〔Tre, Tuoi. (Vietnam OKs bauxite mines. ) ''Vietnews.'' 10 April 2009.〕 Despite its large reserves, Vietnam produces only 30,000 tons of bauxite per year.〔(Bauxite and Alumina ) ''U.S. Geological Survey, Mineral Commodity Summaries.'' January 2009.〕 == 21st century plans for bauxite production expansion == A draft mining plan for bauxite was approved by the Vietnamese government in 2007. Vinacomin, a Vietnamese mining company, has laid out a plan for 6 bauxite mining projects covering over 1800 square kilometers in Vietnam's mountainous Central Highlands. The first two processing plants for the plan have been contracted to Chalco, a Chinese mining company. The Nhan Co project in Dak Nong Province and the Tan Rai complex in Lâm Đồng Province are expected to produce 600,000 tons of alumina per year.〔(Vietnam bauxite decision may affect Alcoa project. ) ''Reuters.'' 29 April 2009.〕 Vietnam has indicated that it needs about $15.6 billion to invest in major bauxite and alumina refining projects by 2025. Prime Minister Nguyễn Tấn Dũng has approved several large mining projects for the Central Highlands, asserting that bauxite exploitation is "a major policy of the party and the state."〔Hoang, Duy. (Vietnam bauxite plan opens pit of concern. ) ''Asia Times Online.'' 17 March 2009.〕 The mining plans have met with strong criticism from scientists, environmentalists and Vietnam's general population.〔(Vietnam scientists clash with government over bauxite project. ) ''Viet Tan.'' 10 April 2009.〕 Forests and agricultural land used by coffee and tea farmers are threatened by the plans and opponents have raised concerns about the toxic waste red mud generated through the refinement of bauxite. Vietnamese general Vo Nguyen Giap has offered strong criticism of the plans, saying that a 1980s study led to experts advising against mining due to severe ecological damage.〔Lam, Tran Dinh Thanh. (Vietnam farmers fall to bauxite bulldozers. ) ''Asia Times.'' 2 June 2009.〕 In March 2010, Google indicated that malicious software targeting Vietnamese opponents of bauxite mining had infected potentially tens of thousands of users.〔Mehta, Neel. (The chilling effects of malware. ) ''Google Online Security Blog.'' 30 March 2010.〕 The malware was used in denial-of-service attacks against dissenting political blogs and installed itself after users downloaded altered Vietnamese language software. The malware was also used to spy on users. The cyber attacks appeared to be a politically motivated attack, according to George Kurtz of McAfee.〔(Google says Vietnam mine opponents under cyber attack. ) ''BBC News.'' 31 March 2010.〕 Vietnamese Foreign Ministry Spokesperson Nguyen Phuong Nga claimed such comments were groundless.〔Kirk, Jeremy. (Vietnam Rebuffs Hacking Claims From Google. ) ''PC World.'' 6 April 2010.〕 In November 2010, Nguyen Tan Dung, the prime minister of Vietnam, announced that Vietnam's bauxite deposits might total 11,000 Mt; this would be the largest in the world.〔(【引用サイトリンク】accessdate=2010-11-28 )〕 ==Companies involved== * Vinacomin (Vietnam National Coal and Mineral Industries Group) * United Company RUSAL has struck a deal with a Vietnamese firm to build an alumina refinery using bauxite from a deposit in the Bình Phước Province〔 * Chalco, (Aluminum Corporation of China Limited) 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「Bauxite mining in Vietnam」の詳細全文を読む スポンサード リンク
