Copper Range Company
The Copper Range Company was a major copper-mining company in the Copper Country of Michigan, United States. It began as the Copper Range Company in the late 19th century as a holding company specializing in shares in the copper mines south of Houghton, Michigan. The company was bought by Louisiana Land and Exploration in 1977. Amygdaloid native copper mining Copper Range controlled through share ownership the Copper Range Railroad and the Baltic Mining Company. The Copper Range Railroad served much of the southern part of the Copper Country, and the Baltic Mining Company owned the copper mine at Baltic, Michigan. In 1901, the Copper Range Company, prevented by Michigan law from issuing more shares of stock, incorporated a new entity in New Jersey, the Copper Range Consolidated Company. Copper Range Consolidated used its new shares to get control of more copper mining companies by stock swaps. It gained half the stock in the Champion mine. The company swapped shares to acquire n ...

Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

HudBay Minerals
Hudbay Minerals Inc. is a diversified Canadian mining company primarily producing copper concentrate (containing copper, gold, and silver) and zinc metal. Much of its history has centered on Flin Flon, Manitoba, where it has mined for over 90 years. Hudbay currently has operations in Manitoba and Peru, and is working towards building a copper mine in southern Arizona. The company also has exploration properties in Canada, Peru, Chile and the United States. History Hudson Bay Mining and Smelting Co. The Flin Flon orebody was discovered by David Collins, a local trapper, and shown to prospector Tom Creighton in 1914. The first claim was registered in 1915. It took more than a dozen years to bring the mine into production because the huge, high grade ore body required large amounts of hydro energy, was isolated, and copper production required a smelter. In 1927, Cornelius Vanderbilt Whitney (a member of the Whitney family of New York), along with Newmont Mining Corp and Mining Co ...

Echo Bay Mines Limited
Echo Bay Mines Limited was a Canadian company which was organized in 1964 by Northwest Explorers Limited to develop a silver deposit at Great Bear Lake, Northwest Territories, Canada, which had been staked in 1930 by The Consolidated Mining and Smelting Company. The company leased the old Port Radium settlement from Eldorado Mining and Refining Limited and used the old camp and mill to recover silver and copper values from what became known as the Echo Bay Mine. Production in the Echo Bay workings ceased in 1975. The company then reopened the old Eldorado Mine workings and produced more silver and copper until 1981 when low silver prices closed the mine for good. Echo Bay Mines Limited went on to open a new gold mine by that point, Lupin Mine, in what was then the Northwest Territories and is today in Nunavut. It entered production in 1982. Echo Bay Mines Limited developed numerous other properties, mostly in the United States, including two mines in Nevada, McCoy/Cove and Roun ...

Louisiana Land And Exploration
Louisiana , group=pronunciation (French: ''La Louisiane'') is a state in the Deep South and South Central regions of the United States. It is the 20th-smallest by area and the 25th most populous of the 50 U.S. states. Louisiana is bordered by the state of Texas to the west, Arkansas to the north, Mississippi to the east, and the Gulf of Mexico to the south. A large part of its eastern boundary is demarcated by the Mississippi River. Louisiana is the only U.S. state with political subdivisions termed parishes, which are equivalent to counties, making it one of only two U.S. states not subdivided into counties (the other being Alaska and its boroughs). The state's capital is Baton Rouge, and its largest city is New Orleans, with a population of roughly 383,000 people. Some Louisiana urban environments have a multicultural, multilingual heritage, being so strongly influenced by a mixture of 18th century Louisiana French, Dominican Creole, Spanish, French Canadian, Acad ...

Dashaveyor
The Dashaveyor was an automated guideway transit (AGT) system developed during the 1960s and '70s. Originally developed by the Dashaveyor Company for moving cargo, the system used motorized pallets that could be routed on the fly to any destination in an extended network. The pallets could run at high speeds between stations, climb steep grades at slower speeds, and even climb vertically. They were designed to replace several manned vehicles with a single automated one, controlled from a central operating station. One such system was installed and operated at the White Pine mine from 1968 to 1972, but was considered a failure. Bendix Corporation purchased the rights to the basic Dashaveyor system in order to use it as the basis for an AGT system during the heyday of urban transport research in the late 1960s. Often referred to as the Bendix-Dashaveyor in this form, the system used the basic design of the cargo system, but with a larger passenger body running on rubber wheels. ...

Nonesuch Shale
The Nonesuch Shale is a Proterozoic geologic formation that outcrops in Michigan and Wisconsin, United States, but has been found by drill holes to extend in the subsurface as far southwest as Iowa. The Nonesuch is a lacustrine sequence of shale, siltstone, and sandstone, 150 to 210 m thick, that conformably overlies the alluvial Copper Harbor Conglomerate and is conformably overlain by the fluvial Freda Sandstone. Together, the Copper Harbor, Nonesuch, and Freda make up the Oronto Group. The Nonesuch is Middle Proterozoic, with an estimated age of approximately 1.1 billion years. It was deposited in the Midcontinent Rift. The Nonesuch beds contain common organic carbon and pyrite. Natural resources The Nonesuch Formation has been a major source of copper, and is considered a prospective source of petroleum. Copper Copper was discovered in the Nonesuch in the 1800s, but early mining efforts, such as those at the Nonesuch Mine in Ontonagon County, Michigan, failed becau ...

Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...

Siltstone
Siltstone, also known as aleurolite, is a clastic sedimentary rock that is composed mostly of silt. It is a form of mudrock with a low clay mineral content, which can be distinguished from shale by its lack of fissility.Blatt ''et al.'' 1980, pp.381-382 Although its permeability and porosity is relatively low, siltstone is sometimes a tight gas reservoir rock, an unconventional reservoir for natural gas that requires hydraulic fracturing for economic gas production. Siltstone was prized in ancient Egypt for manufacturing statuary and cosmetic palettes. The siltstone quarried at Wadi Hammamat was a hard, fine-grained siltstone that resisted flaking and was almost ideal for such uses. Description There is not complete agreement on the definition of siltstone. One definition is that siltstone is mudrock ( clastic sedimentary rock containing at least 50% clay and silt) in which at least 2/3 of the clay and silt fraction is composed of silt-sized particles. Silt is defined a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chalcocite
Chalcocite (), copper(I) sulfide (Cu2S), is an important copper ore mineral. It is opaque and dark gray to black, with a metallic luster. It has a hardness of 2.5–3 on the Mohs scale. It is a sulfide with a monoclinic crystal system. The term ''chalcocite'' comes from the alteration of the obsolete name ''chalcosine'', from the Greek ''khalkos'', meaning "copper". It is also known as redruthite, vitreous copper, or copper-glance. Occurrence Chalcocite is sometimes found as a primary vein mineral in hydrothermal veins. However, most chalcocite occurs in the supergene enriched environment below the oxidation zone of copper deposits as a result of the leaching of copper from the oxidized minerals. It is also often found in sedimentary rocks. It has been mined for centuries and is one of the most profitable copper ores. The reasons for this is its high copper content (66.7% atomic ratio and nearly 80% by weight) and the ease at which copper can be separated from sulfur. ...
