In 2011, Namibia was ranked as the 4th largest producer of uranium worldwide, behind Kazakhstan, Canada, and Australia. When Uranium prices fell after the Fukushima incident production was reduced. In 2012, Namibia produced 7.1% of Uranium oxide worldwide, trailing behind Niger as well.〔 Some of the factual statements are only available in the offline version of this article.〕 ==Background and history== Uranium mineralization was first discovered in the Namibia's Rossing Mountains, Namib Desert in 1928 by Capt. G. Peter Louw. Though he tried promoting prospecting, it did not occur for another three decades. In the late 1950s, Anglo-American Corp of South Africa drilled and performed some underground exploration, but because of unstable uranium values and poor economic prospects, the search was abandoned. Uranium exploration was restarted in the country in the following decade, with Rio Tinto obtaining exploration rights for the Rössing deposit in 1966 and starting production in 1976. The United Nations held special hearings on "The plunder of Namibian uranium" in 1980. Jacob ''et al.'' reported in the mid-1980s that the country's uranium mineralization was concentrated in the Central Zone of the Pan-African Damaran Orogen. In 1999, the International Atomic Energy Agency reported that the only operating mine in the county was the Rössing uranium mine, the largest uranium mine the world. However, there has been a resurgence in the industry since 2003, and in 2008 uranium mine production in the whole of Africa increased by 16% compared to the previous year. Primary mines have since been opened, including Valencia, Ida Dome, and Goanikontes, as well as two secondary mines, Langer Heinrich (started in 2006) and Trekkopje (started in 2012).〔 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「Uranium mining in Namibia」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
