COMINAK (Compagnie minière d'Akokan) is a national uranium mining company of Niger. It is a joint venture between the French company Areva NC and the state of Niger, which operates in the field of mining. COMINAK was established in 1974, following a memorandum of understanding between France, Japan and Niger. They commenced uranium production in 1978, and reached a record production in 1981 with 2,260 tons of uranium. COMINAK's plant is installed in Akokan, not far from the town of Arlit.〔 COMINAK is one of two national mining companies in Niger, the other being SOMAIR in the nearby Akokan.〔 ==History== The earliest reported exploration for uranium started in 1956 was initially by the French Atomic Energy Commission (CEA) which was continued by COGEMA. This was followed by extraction of the mines at Akouta and Akola by COMINAK. In 1970, France-Japan-Niger research signed an agreement on the scope of exploitation of Akouta underground mines.〔 COMINAK then became the second in the line of firms established to mine and process uranium in Niger. The consortium was founded in 1971, but it is in business of uranium mining in Niger after establishing its plant in 1978, and since then has progressively expanded its interest over the years. Its active mines in Nigeria are the underground mines which are claimed as the largest underground mines in the world. However, in 1975 the leasing or transfer of mining rights of Akouta’s area to COMINAK was concluded by COGEMA. In 1981 COMANAC mines achieved the maximum production rate 2,260 metric tons per year; however, in 1986 the production rate per year was restricted to 1,960 metric tons. Akola area was leased to COMINAK for extraction, in 1987. In 1998, uranate, the processed uranium of 40 million tons was packed under containers, which was followed by signing of a new mining agreement in 2001 for the period 2004-2013. Feasibility study for the Afasto site was initiated and the extraction of the mines was started during 2007. ISO 14001 certification on sustainable development and environmental protection was given in 2003, renewed in 2006 and 2008. A rectification and development plan was also launched for the period 2006-08. During 2006 the Agebout and Afouday areas were also taken up for exploration studies. COMINAK was granted a mining permit in 2006 to operate in the southern part of the Ebba deposit. The Imourarean ore area, located 80 km to the south of Arlit, which was first discovered in 1969, was also explored in 2006 considering the favorable market condition for uranium in the world. Mining at this large mine was started in 2011.〔 It is now the second largest active uranium mine in the African continent. The reserves were expected to last for another 15 years as of 2010 at the extraction rate of 1,433 metric tons of concentrate.〔 The Akouta region, where uranium concessions are operational since 1978, is west of Arlit; the mines were discovered in 1966-67 by the French Atomic Energy Commission (CEA). When established the programme was to have a production rate of 2000 tons of processed ore by 1980. The second company to be established to mine and process uranium in Niger, its plant became operational in 1978. 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「COMINAK」の詳細全文を読む スポンサード リンク
