Mining industry of Libya : ウィキペディア英語版 | Mining industry of Libya
The mining industry of Libya does not contribute significantly to its economy. Mining resources are located in remote regions with limited accessibility. The fuel sector, including oil reserves (which have a capacity of 29.5 billion barrels) and natural gas (which has 1.31 trillion cubic meters of reserve) is the major revenue-generating industry. Africa's largest proven oil reserves are in Libya. The first well was drilled in 1956 and oil was struck in the following year. The Wadi ash-Shati' may hold one of the world's biggest iron ore deposits. ==Production and impact== The identified sources of minerals relate to diamondiferous kimberlites in the East Saharan craton and metamorphic belts with potential for gold in the southern region of the country. Large gypsum deposits have produced 150,000 tons per year for the manufacture of cement. Other sources include sulfur extraction (about 13,000 tons/year) as a byproduct of refining petroleum and natural gas. Iron ore from Wadi ash-Shati', approximately from the sea, is also of note, with a reserve identified of 795 million tons of 52% grade. This has not been extracted due to the remoteness of its location.〔 Substantial reserves of magnesium and potassium salts have been recorded, but apart from magnetite, phosphate rock, and sulfur, these are yet to be mined. There are large salt flats in the north; production in the 1980s amounted to 11,000 tons of salt per annum. Oil fields include the Bouri Field, the Mediterranean's largest producing oilfield;〔(Middle East Reservoir Review )〕 El Sharara, Elephant, Raguba, Sarir, Waha, and Zelten.
