Jan 01, 2006 The Blackbird copper mine, at the southeast end of the anticline, shipped several thousand tons of copper ore to the Kennecott smelter north of the Bingham mine at Magna in the 1950s. The old Blackbird copper mine returned to production in the 1960s with construction of a 200-ton-per-day acid leach plant.
Mining activities remained relatively limited until 1906 when the district became the first in the world to begin large-scale (for the time) open-pit copper mining (for more mine history, see Race to Ore The Beginnings of Open-Pit Copper MiningA Century of Open-Pit Mining at Bingham Canyon in Survey Notes, v. 39, no. 2).

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
As a primary ore, platinum has never been mined in Arizona its only production has come from trace amounts recovered in the final stage of refining copper ores. The geologic environment of Arizona, diverse as it is, does not encourage the search for platinum-group metals, graphite, cobalt, nickel, bauxite, diamonds, and a number of other ...
World-class ore deposits. Exploration conducted by mining stakeholders, both public and private, has led to the discovery of several sizable ore deposits in Qubec, many of which are considered world-class, namely the Horne, Gasp Copper, Selbaie (former producers) and LaRonde mines for base metals, and the Doyon and Sigma-Lamaque mines for gold.

Many of the Surveys early publications describe Idahos natural wealth of mineral resources, both metallic minerals and industrial or non-metallic minerals. The Idaho Bureau of Mines and Geology (IBMG) Pamphlet series includes most of these early works on the
While most mines operate with copper concentrations of between 0.2 and 0.8 %, some of the richest ore bodies, located in central to southern Africa, can contain 5 6% copper. According to the US Geological Survey, since 1950, reports have regularly shown that there have always been, on average, 40 years of copper reserves and over 200 years ...

The Encampment mining district in the Sierra Madre mainly produced copper after its discovery in 1874. However, gold and silver were significant byproducts of copper mining. The Encampment (also known as the Grand Encampment) district includes the entire Sierra Madre in south-central Wyoming and extends into Colorado.
Jul 23, 2015 Copper as well as a number of other commodities are harvested by solution mining methods. Water-soluble salts such as potash (sylvite), rock salt (halite), thenardite (sodium sulfate) and nahcolite (sodium bicarbonate) are commonly derived from massive sedimentary deposits by in-situ methods. Most of the sulfur produced in the Gulf of Mexico region is recovered by a solution mining
For already-mined resources, the estimated pre-mining geologic resource is based on assumption of 85% of the original geologic resource extracted during underground mining and 90% of copper recovered by the mill. Data sources previously mined copper in the Keweenaw Peninsula from Weege and Pollack (1971) and unmined native copper from unpublished

The geologic characteristics of porphyry copper deposits recently have been reviewed by John and others (2010), Sinclair (2007), and Seedorff and others (2005). Therefore, only salient features are summarized here. Porphyry copper deposits are found around the world, most commonly in areas with active or ancient volcanism (Fig. 2).
Vermont copper mines operated sporadically through the 1950s, and the closing of the Elizabeth Mine in 1958 brought an end to metal mining in Vermont. Ore minerals have not been exhausted in the Orange County copper district, but the ore grade is marginal and structural complexity makes mining extremely difficult (Ratte, 1982).
May 09, 2013 It was 1943 and World War II raged on and Allied Forces were on the offensive in the Pacific and European theaters. Back home mineral exploration for critical minerals was essential to the war effort. As part of this effort, geologists of the Arizona Bureau of Mines meticulously mapped the geology of the copper-rich Superior mining area of Arizona.

Because of its geologic similarity to important metal mining districts in Canada, the Carolina Slate Belt has been an area of extensive exploration. It is considered a good site for the discovery of base metal deposits (copper, lead and zinc) and gold associated with ancient hot-spring systems.
