Champion Mining Company
The Champion Mining Company was created in 1899 to manage the Champion Mine located in the heart of copper country in Painesdale, Michigan, United States. The Champion Mine in Painesdale was closed in 1967. The Champion #4 Shaft-Rock house is the oldest shaft-rock house standing in the Keweenaw. Champion #4 was one of the many Copper Range Company mines that ran from Atlantic Mine to Painesdale. During the 1930s the mine was working the 48th level, 4,800 feet from the surface on the incline at the #4 shaft house. Some buildings and many ruins remain from this once active mine. Although primarily a copper mine, the Champion Mine also contained prehnite and 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. ... deposits.

Copper Country
The Copper Country is an area in the Upper Peninsula of Michigan in the United States, including Keweenaw County, Michigan, Houghton, Baraga and Ontonagon counties as well as part of Marquette County. The area is so named as copper mining was prevalent there from 1845 until the late 1960s, with one mine (the White Pine mine) continuing through 1995. In its heyday in the latter half of the 19th century and the early 20th century, the area was the world's greatest producer of copper. Native copper Copper Country is highly unusual among mining districts in that the copper mined was predominantly in its elemental (" native") form, rather than in the form of compounds (mostly oxides and sulfides) that form the basis of the copper ore at almost every other copper-mining district. History Native Americans mined copper from small pits as early as 3000 B.C. on this peninsula surrounded by the waters of Lake Superior. Douglass Houghton, the State Geologist of Michigan in th ...

Painesdale, Michigan
Painesdale is an unincorporated community in Houghton County, Michigan, United States. Painesdale is located in Adams Township along M-26, southwest of South Range. Painesdale has a post office with ZIP code 49955. History Painesdale was built by the Champion Mining Company between 1899 and 1917, and named after the Boston businessman William A. Paine, who was associated with many mines as well as the Paine Webber brokerage. Painesdale was located near the copper load, and the company designed the town following theories of efficient planning. In 1993, the town was added to the National Register of Historic Places The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artist ....Bogue, Margaret Beattie (2007)''Around the Shores of Lake Superior: A Guide to Historic Sites'' p. 300.

Copper Mine
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals. It is then concentrated using mineral flotation. The concentrate is typically sold to distant smelters, although some large mines have smelters located nearby. Such colocation of mines and smelters was more typical in the 19th and early 20th centuries, when smaller smelters could be economic. The sulfide concentrates are typically smelted in such furnaces as the Outokumpu or I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prehnite
Prehnite is an inosilicate of calcium and aluminium with the formula: Ca2Al(AlSi3O10)(OH)2. Limited Fe3+ substitutes for aluminium in the structure. Prehnite crystallizes in the orthorhombic crystal system, and most often forms as stalactitic or botryoidal aggregates, with only just the crests of small crystals showing any faces, which are almost always curved or composite. Very rarely will it form distinct, well-individualized crystals showing a square-like cross-section, including those found at the Jeffrey Mine in Asbestos, Quebec, Canada. Prehnite is brittle with an uneven fracture and a vitreous to pearly luster. Its hardness is 6-6.5, its specific gravity is 2.80-2.90 and its color varies from light green to yellow, but also colorless, blue, pink or white. In April 2000, rare orange prehnite was discovered in the Kalahari Manganese Fields, South Africa. Prehnite is mostly translucent, and rarely transparent. Though not a zeolite, prehnite is found associated with minerals su ... [...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. ...
