Jarosite
Jarosite is a basic hydrous sulfate of potassium and ferric iron (Fe-III) with a chemical formula of KFe3(SO4)2(OH)6. This sulfate mineral is formed in ore deposits by the oxidation of iron sulfides. Jarosite is often produced as a byproduct during the purification and refining of zinc and is also commonly associated with acid mine drainage and acid sulfate soil environments. Physical properties Jarosite has a trigonal crystal structure and is brittle, with basal cleavage, a hardness of 2.5-3.5, and a specific gravity of 3.15-3.26. It is translucent to opaque with a vitreous to dull luster, and is colored dark yellow to yellowish-brown. It can sometimes be confused with limonite or goethite with which it commonly occurs in the gossan (oxidized cap over an ore body). Jarosite is an iron analogue of the potassium aluminium sulfate, alunite. Solid solution series The alunite supergroup includes the alunite, jarosite, beudantite, crandallite and florencite subgroups. The aluni ...

Porphyry Copper Deposit
Porphyry copper deposits are copper ore bodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the deposit itself. Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its name. In later stages, circulating meteoric fluids may interact with the magmatic fluids. Successive envelopes of hydrothermal alteration typically enclose a core of disseminated ore minerals in often stockwork-forming hairline fractures and veins. Because of their large volume, porphyry orebodies can be economic from copper concentrations as low as 0.15% copper and can have economic amounts of by-products such as molybdenum, silver, and gold. In some mines, those metals are the main product. The first mining of low-grade copper porphyry deposits from large open pits coincided roughly with the introduction of steam shovels, the construction of railroads, and a surge ...

Zinc Sulfate
Zinc sulfate is an inorganic compound. It is used as a dietary supplement to treat zinc deficiency and to prevent the condition in those at high risk. Side effects of excess supplementation may include abdominal pain, vomiting, headache, and tiredness. The most common form includes water of crystallization as the heptahydrate, with the formula . It was historically known as "white vitriol". Zinc sulfate and its hydrates are colourless solids. Uses Medicine In medicine it is used together with oral rehydration therapy (ORT) and an astringent. Manufacturing The hydrates, especially the heptahydrate, are the primary forms used commercially. The main application is as a coagulant in the production of rayon. It is also a precursor to the pigment lithopone. It is also used as an electrolyte for zinc electroplating, as a mordant in dyeing, and as a preservative for skins and leather. Other Zinc sulfate is used to supply zinc in animal feeds, fertilizers, toothpaste, and agricul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gunningite
Gunningite is one of the minerals in the Kieserite group, with the chemical formula . Its name honours Henry Cecil Gunning (1901–1991) of the Geological Survey of Canada and a professor at the University of British Columbia. Occurrence Gunningite is rare. It is found in dry areas of the oxidized portions of sphalerite-bearing deposits. It has been noted in mines in Canada (Yukon Territory, British Columbia and New Brunswick), the United States (Nevada and Arizona), Switzerland (Valais), Greece, Attica and Germany (Baden-Württemberg).

Ottawa
Ottawa (, ; Canadian French: ) is the capital city of Canada. It is located at the confluence of the Ottawa River and the Rideau River in the southern portion of the province of Ontario. Ottawa borders Gatineau, Quebec, and forms the core of the Ottawa–Gatineau census metropolitan area (CMA) and the National Capital Region (NCR). Ottawa had a city population of 1,017,449 and a metropolitan population of 1,488,307, making it the fourth-largest city and fourth-largest metropolitan area in Canada. Ottawa is the political centre of Canada and headquarters to the federal government. The city houses numerous foreign embassies, key buildings, organizations, and institutions of Canada's government, including the Parliament of Canada, the Supreme Court, the residence of Canada's viceroy, and Office of the Prime Minister. Founded in 1826 as Bytown, and incorporated as Ottawa in 1855, its original boundaries were expanded through numerous annexations and were ultimately ...

Geological Survey Of Canada
The Geological Survey of Canada (GSC; french: Commission géologique du Canada (CGC)) is a Canadian federal government agency responsible for performing geological surveys of the country, developing Canada's natural resources and protecting the environment. A branch of the Earth Sciences Sector of Natural Resources Canada, the GSC is the country's oldest scientific agency and was one of its first government organizations. History In September 1841, the Province of Canada legislature passed a resolution that authorized the sum of £1,500 sterling be granted to the government for the estimated expense of performing a geological survey of the province. In 1842, the Geological Survey of Canada was formed to fulfill this request.Christy Vodden (1992)No Stone Unturned: The First 150 years of the Geological Survey of Canada Geological Survey of Canada Web site William Edmond Logan was in Montreal at the time and made it known that he was interested in participating in this survey.

Campbell River (Vancouver Island)
The Campbell River is a river on Vancouver Island, British Columbia, Canada. It drains into Discovery Passage at the northwest end of the Strait of Georgia at the City of Campbell River. The Kwak'wala name for the river, or for the village near its mouth, at Campbell River Indian Reserve No. 11, is ''Tla'mataxw''. The source of the river is Buttle Lake. Name origin The river was named for Dr. Samuel Campbell, ship's surgeon aboard from 1857 to 1861. Campbell Bay on Mayne Island and Samuel Island were also named for him, as may also have been Campbell Point on Loughborough Inlet and Campbell Island, the location of the community of Bella Bella, and Plumper's Cove on Keats Island. Hydroelectricity Three hydroelectric dams are located on the Campbell River: the John Hart Dam, finished in 1947, which impounds John Hart Lake; upstream, the Ladore Dam, completed in 1949 on Lower Campbell Lake; and the Strathcona Dam, completed 1958, impounding Upper Campbell Lake Upper Camp ...

Keno Hill, Yukon
Keno City is a small community in Yukon, Canada at the end of the Silver Trail highway. Keno City was the site of a former silver- lead mining area proximal to Keno Hill. Keno City is 13 kilometres away from Elsa, Yukon, which is owned by Hecla mining who currently own and operate the various Ag-Pb-Zn deposits in the Keno Hill area. Rich silver and lead ore deposits were found on Keno Hill in 1919, and since then the population of the community has fluctuated in response to the mining activity in the area. When in 1989 United Keno Hill closed the mines, literally overnight, the people in the Keno area who decided to stay chose a more sustainable economy: tourism. They successfully marketed Keno City as a quiet, tranquil community. History Keno City was named after the gambling game Keno popular in mining camps at the turn of the 20th century. A small placer mining operation is behind Keno City, indicating the present support for active disturbance of earth materials t ...

Fault Zone
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...

Groundwater
Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available freshwater in the world is groundwater. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology. Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil moisture, perma ...

Deposits
A deposit account is a bank account maintained by a financial institution in which a customer can deposit and withdraw money. Deposit accounts can be savings accounts, Transaction account#Current accounts, current accounts or any of several other types of accounts explained below. Transactions on deposit accounts are recorded in a bank's books, and the resulting balance is recorded as a Liability (accounting), liability of the bank and represents an amount owed by the bank to the customer. In other words, the banker-customer (depositor) relationship is one of debtor-creditor. Some banks charge fees for transactions on a customer's account. Additionally, some banks pay customers Interest (finance), interest on their account balances. Types of accounts * How banking works In banking, the verbs "deposit" and "withdraw" mean a customer paying money into, and taking money out of, an account, respectively. From a legal and financial accounting standpoint, the noun "deposit" is used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
