Miami Information

  • General 2015-05-10
    Description: Miami includes an open-pit copper mine, an operating smelter and a rod mill. Did you know? The Miami Mine historically has been the major copper producer in the Globe-Miami mining area, one of America's premier copper mining districts. Miami is now conducting an extensive, award-winning reclamation program and is in partnership with other mining companies from the area to remediate contaminated ground water downstream of the historic production sites. Ores: The Miami mine is developed on a porphyry copper deposit that has leachable oxide and secondary sulfide mineralization. The predominant oxide copper minerals are chrysocolla, copper-bearing clays, malachite and azurite. Chalcocite and covellite are the most important secondary copper sulfide minerals. Processes and facilities: SX/EW plant, smelter and rod mill. In October 2009, FCX announced initiatives to resume limited mining activities at the Miami mine. Background: The first prospecting expeditions visited the area in the 1860s. Copper was mined underground until after World War II, when the first open-pit mining began. Miami was among the first to employ “vat leaching” (1926) and precipitation plants to recover oxide minerals. It did this in conjunction with its flotation concentrator, which processed sulfide minerals. The plant'’s smelter was modernized in 1974 to meet Clean Air Act standards and further modernized and expanded in 1992. The success of an SX/EW plant commissioned in 1979 led to the demise of vat leaching by the mid-1980s and ultimately the concentrator in 1986. The rod plant was commissioned in 1966 and refinery in 1993.

    Democratic Republic of Congo state miner Gecamines has challenged Freeport McMoRan Inc's sale of its majority stake in the Tenke copper mine at the International Court of Arbitration in Paris, Gecamines said on Wednesday. Gecamines Secretary-general Deogratias Ngele told Reuters that Gecamines had asserted a right of first offer following Freeport's agreement in May to sell its 56% stake in Tenke, one of the world's largest copper mines, to China Molybdenum for $2.65-billion.

    Gecamines, the State-owned miner in the Democratic Republic of Congo, said any decision by Lundin Mining to also withdraw from the Tenke Fungurume copper mine could present another obstacle to Freeport McMoRan’s proposed sale of its stake in the project. By exiting at the same time and transferring full ownership of the project to new parties without securing Gecamines’ approval, Lundin and Freeport would be further violating the state-owned miner’s rights, Chairman Albert Yuma said by e-mail Friday. Gecamines must be permitted to match the offers for the stake, or it could stop any deal going through, he said.
