Quincy Smelting Works
The Quincy Smelter, also known as the Quincy Smelting Works, is a former copper smelter located on the north side of the Keweenaw Waterway in Ripley, Michigan. It is a contributing property of the Quincy Mining Company Historic District, a National Historic Landmark District. The smelter was built in 1898 by the Quincy Mining Company, operating from 1898 to 1931 and again from 1948 to 1971. The smelter was part of a Superfund site from 1986 to 2013. History Operational years The Quincy Mining Company incorporated in 1848. Like other mines in the area, Quincy had its own stamp mills, but did not produce enough copper to justify the investment of operating its own smelter. Before 1860, when the Lake Superior Smelter opened in Hancock, copper was shipped out to be smelted in cities such as Boston or Detroit. By the late 1890s, the quantity of rock mined by Quincy justified the company building its own smelter. In May 1898, the Quincy Mining Company started construction of the ...

National Priorities List
The National Priorities List (NPL) is the priority list of hazardous waste sites in the United States eligible for long-term remedial investigation and remedial action (cleanup) financed under the federal Superfund program. Environmental Protection Agency (EPA) regulations outline a formal process for assessing hazardous waste sites and placing them on the NPL. The NPL is intended primarily to guide EPA in determining which sites are so contaminated as to warrant further investigation and significant cleanup. As of 2022, 1333 sites are on the list, and 43 sites have been proposed for listing. 448 sites have been deleted from the list. Process for listing The Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), also known as "Superfund", requires that the criteria provided by the Hazard Ranking System (HRS) be used to make a list of national priorities of the known releases or threatened releases of hazardous substances, pollutants, or contamin ...

Environmental Protection Agency
A biophysical environment is a biotic and abiotic surrounding of an organism or population, and consequently includes the factors that have an influence in their survival, development, and evolution. A biophysical environment can vary in scale from microscopic to global in extent. It can also be subdivided according to its attributes. Examples include the marine environment, the atmospheric environment and the terrestrial environment. The number of biophysical environments is countless, given that each living organism has its own environment. The term ''environment'' can refer to a singular global environment in relation to humanity, or a local biophysical environment, e.g. the UK's Environment Agency. Life-environment interaction All life that has survived must have adapted to the conditions of its environment. Temperature, light, humidity, soil nutrients, etc., all influence the species within an environment. However, life in turn modifies, in various forms, its conditions. ...

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. The ... deposits.

Quincy Dredge Number Two
The Quincy Dredge Number Two (previously known as the Calumet and Hecla Dredge Number One) is a dredge currently sunk in shallow water in Torch Lake, across M-26 from the Quincy Mining Company Stamp Mills Historic District and just east of Mason in Osceola Township. It was constructed to reclaim stamping sand from the lake for further processing, and was designated a Michigan State Historic Site in 1978. History The Reclaiming Sand Dredge was constructed for the Calumet and Hecla Mining Company in 1914 by the Bucyrus Company of South Milwaukee, Wisconsin, and designated the Calumet and Hecla Dredge Number One. The dredge was used to reclaim previously-milled sand deposited in the lake after it had gone through the stamp mill. The dredged sand contained copper that earlier stamping technology had not been able to separate out. Improvements in stamping efficiency and cost increases in traditional shaft mining made these sand tailings economically feasible to reclaim and ...

Michigan Smelter
The Michigan Smelter was a copper smelter located at Cole's Creek on the Keweenaw Waterway north-west of Houghton, Michigan near the old Atlantic mill. The smelter was created in 1903-4 as a joint effort between the Copper Range Company and Stanton group of mines. An Atlantic dam on the site was reused by the smelter as a water source.Stevens, Horace. ''The Copper Handbook'' Volume 6. 1906. Pages 683--684Google books/ref> In 1905, the smelter broke a world record by casting 292,000 pounds of fine copper in seven hours with a single furnace and only ten men. The smelter operated through World War II and stopped all operations in 1948. The smelter was designed by Frank Klepetko and was the most modern plant in the district. The nearby hillside was used improve its efficiency of its operation.Lankton, Larry. ''Hollowed ground: copper mining and community building on Lake Superior'' 201Google bookspage 149.

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 ...

Tailings
In mining, tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are different to overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to concentrate the valuable minerals, or hard rock mining, which pulverizes the rock containing the ore and then relies on chemical reactions to concentrate the sought-after material. In the latter, the extraction of minerals from ore requires comminution, i.e., grinding the ore into fine particles to facilitate extraction of the target element(s). Because of this comminution, tailings consist of a slurry of fine particles, ranging from the size of a grain of sand to a few micrometres. Mine tailings are usually produced from the mill in slurry form, which i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quincy Mining Company Stamp Mills Historic District
The Quincy Mining Company Stamp Mills Historic District is a historic stamp mill (used to crush copper-bearing rock, separating the copper ore from surrounding rock) located on M-26 near Torch Lake, just east of Mason in Osceola Township. It was listed on the National Register of Historic Places in 2007. Original stamp mill (1860–1888) The original Quincy Stamp Mill was built in 1860 on Portage Lake in Hancock, close to the Quincy Mine. This facility, however, dumped an enormous amount of sand tailings into the lake, and the sand soon threatened to encroach on the navigable channel of the lake. In the mid-1880s, the federal government set minimum harbor lines and stiff penalties for breaching them, and eventually filed suit against the Quincy Mine for dumping in Portage Lake. In addition, Quincy was in the process of acquiring the nearby Pewabic Mine, and management knew they would need to increase the company's stamping capacity. Stamp mills require a large amoun ...

Torch Lake (Houghton County, Michigan)
Torch Lake is an approximately lake lying mostly within Torch Lake Township with portions within Osceola and Schoolcraft townships in Houghton County in the U.S. state of Michigan. The lake is fed by the Traprock River. The village of Lake Linden at the north end of the lake was once the site of the largest copper milling operation in North America. About of copper mill stamp sands were dumped into Torch Lake itself, filling about 20 percent of the lake's volume. The Environmental Protection Agency believes the contaminated sediments to be thick in some areas, and surface sediments contain up to 2,000 parts per million (ppm) of copper. The lake is about east-northeast of Houghton and is approximately long and wide at . The lake has a total surface area of , and a maximum depth of . A channel drains from the lake south into Torch Bay, which opens into Portage Lake. See also *List of lakes in Michigan This is a list of lakes in Michigan. The American state of Michigan ...
