Kellogg, Idaho
Kellogg is a city in the Silver Valley of Shoshone County, Idaho, United States, in the Idaho Panhandle region. The city lies near the Coeur d'Alene National Forest and about 36 miles (58 km) east-southeast of Coeur d'Alene along Interstate 90. As of the 2010 United States Census, the city had a total population of 2,120, down by a third from its population in 1980. History Kellogg was incorporated in 1907. The city limits included mine property in 1955, and smelter property in 1956. The population in 1960 was about 6000. Kellogg is named after a prospector named Noah Kellogg. After nearly a century of bustling activity in the mines, including a history of disputes between union miners and mine owners, the Bunker Hill Mine (& smelter) closed in 1981, leaving thousands out of work and a history of lead contamination. Other mines reduced operations, as well. Since the mines have closed, Kellogg has been moving more towards a resort town; the development of new condo ...

City
A city is a human settlement of notable size.Goodall, B. (1987) ''The Penguin Dictionary of Human Geography''. London: Penguin.Kuper, A. and Kuper, J., eds (1996) ''The Social Science Encyclopedia''. 2nd edition. London: Routledge. It can be defined as a permanent and densely settled place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organisations and businesses, sometimes benefiting different parties in the process, such as improving efficiency of goods and service distribution. Historically, city-dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization, more than half of the world population now lives in cities, which has had profound consequences for g ...

Bunker Hill Smelter Operating In Winter Snow, 1970s
A bunker is a defensive military fortification designed to protect people and valued materials from falling bombs, artillery, or other attacks. Bunkers are almost always underground, in contrast to blockhouses which are mostly above ground. They were used extensively in World War I, World War II, and the Cold War for weapons facilities, command and control centers, and storage facilities. Bunkers can also be used as protection from tornadoes. Trench bunkers are small concrete structures, partly dug into the ground. Many artillery installations, especially for coastal artillery, have historically been protected by extensive bunker systems. Typical industrial bunkers include mining sites, food storage areas, dumps for materials, data storage, and sometimes living quarters. When a house is purpose-built with a bunker, the normal location is a reinforced below-ground bathroom with fiber-reinforced plastic shells. Bunkers deflect the blast wave from nearby explosions to prevent ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Monoxide
Carbon monoxide (chemical formula CO) is a colorless, poisonous, odorless, tasteless, flammable gas that is slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest molecule of the oxocarbon family. In coordination complexes the carbon monoxide ligand is called carbonyl. It is a key ingredient in many processes in industrial chemistry. The most common source of carbon monoxide is the partial combustion of carbon-containing compounds, when insufficient oxygen or heat is present to produce carbon dioxide. There are also numerous environmental and biological sources that generate and emit a significant amount of carbon monoxide. It is important in the production of many compounds, including drugs, fragrances, and fuels. Upon emission into the atmosphere, carbon monoxide affects several processes that contribute to climate change. Carbon monoxide has important biological roles across phylogenetic ...

SCBA
A self-contained breathing apparatus (SCBA), sometimes referred to as a compressed air breathing apparatus (CABA) or simply breathing apparatus (BA), is a device worn to provide breathable air in an atmosphere that is immediately dangerous to life or health. They are typically used in firefighting and industry. The term ''self-contained'' means that the SCBA is not dependent on a remote supply of breathing gas (e.g., through a long hose). If designed for use under water, it is also known as a Scuba set (self-contained underwater breathing apparatus). When not used underwater, they are sometimes called industrial breathing sets. Unofficial names include ''air pack'', ''air tank'', ''oxygen cylinder'' or simply ''pack'', which are mostly used in firefighting. An SCBA typically has three main components: a high-pressure tank (e.g., , about 150 to 374 atmospheres), a pressure regulator, and an inhalation connection (mouthpiece, mouth mask or face mask), connected together and mount ...

Hopcalite
Hopcalite is the trade name for a number of mixtures that mainly consist of oxides of copper and manganese, which are used as catalysts for the conversion of carbon monoxide to carbon dioxide when exposed to the oxygen in the air at room temperature. The name "hopcalite" is derived from Johns Hopkins University - "Hop" and the University of California - "Cal", where basic research into carbon monoxide was carried out during the First World War and these catalysts were discovered in 1918. A variety of compositions are known, such as "hopcalite II" that is approximately 60% manganese dioxide and 40% copper oxide (the MnO2 : CuO molar ratio is 1.375) and "hopcalite I" that is a mixture of 50% MnO, 30% CuO, 15% Co2O3, and 5% Ag2O. Hopcalite has the properties of a porous mass and resembles activated carbon in its appearance. Preparation While typically hopcalite catalysts are prepared by calcining intimate mixtures of oxides and carbonates, various techniques have been employed f ...

Self-contained Self-rescue Device
Self-sustainability and self-sufficiency are overlapping states of being in which a person or organization needs little or no help from, or interaction with, others. Self-sufficiency entails the self being enough (to fulfill needs), and a self-sustaining entity can maintain self-sufficiency indefinitely. These states represent types of personal or collective autonomy. A self-sufficient economy is one that requires little or no trade with the outside world and is called an autarky. Description Self-sustainability is a type of sustainable living in which nothing is consumed other than what is produced by the self-sufficient individuals. Examples of attempts at self-sufficiency in North America include simple living, food storage, homesteading, off-the-grid, survivalism, DIY ethic, and the back-to-the-land movement. Practices that enable or aid self-sustainability include autonomous building, permaculture, sustainable agriculture, and renewable energy. The term is also applied ...

Mining Accident
A mining accident is an accident that occurs during the process of mining minerals or metals. Thousands of miners die from mining accidents each year, especially from underground coal mining, although accidents also occur in hard rock mining. Coal mining is considered much more hazardous than hard rock mining due to flat-lying rock strata, generally incompetent rock, the presence of methane gas, and coal dust. Most of the deaths these days occur in developing countries, and rural parts of developed countries where safety measures are not practiced as fully. A mining disaster is an incident where there are five or more fatalities. Causes Mining accidents can occur from a variety of causes, including leaks of poisonous gases such as hydrogen sulfide or explosive natural gases, especially firedamp or methane, dust explosions, collapsing of mine stopes, mining-induced seismicity, flooding, or general mechanical errors from improperly used or malfunctioning mining equipment (suc ...

Gondola Lift
A gondola lift is a means of cable transport and type of aerial lift which is supported and propelled by cables from above. It consists of a loop of steel wire rope that is strung between two stations, sometimes over intermediate supporting towers. The cable is driven by a bullwheel in a terminal, which is typically connected to an engine or electric motor. It is often considered a ''continuous system'' since it features a haul rope which continuously moves and circulates around two terminal stations. In contrast, an aerial tramway operates solely with fixed grips and simply shuttles back and forth between two end terminals. The capacity, cost, and functionality of a gondola lift will differ dramatically depending on the combination of cables used for support and haulage and the type of grip (detachable or fixed). Because of the proliferation of such systems in the Alps, the it, Cabinovia and french: Télécabine are also used in English-language texts. The systems m ...

Silver Mountain (Idaho)
Silver Mountain Resort is a ski resort in the northwest United States, located in the Silver Valley region of northern Idaho, just south of Kellogg and Interstate 90 in Shoshone County. Originally opened as "Jackass Ski Bowl" in January 1968 on Wardner Peak, it was renamed "Silverhorn" in 1973 following an ownership change. With planned improvements, most notably the gondola from the city of Kellogg and expansion on Kellogg Peak, the name was changed to "Silver Mountain" in the summer of 1989. History Jackass Ski Bowl Jackass Ski Bowl, near Wardner, was constructed in the summer of 1967 on lands leased from the Bunker Hill Mining Company. It was named for Noah Kellogg's borrowed ore-discovering donkey ''(Jenny)'' of 1885. The ski area began operations in January 1968 and the first seasons were promising, with plans for lift expansion, and a 1971 season that extended to mid-May. But the next two years of poor skiing weather caused the operation to fall into financial diffi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bunker Hill Mining Company
The Bunker Hill Mining Company is a mining company with facilities in Kellogg and Wardner, Idaho. Early history Simeon Reed bought the Bunker Hill Mine and Mill, and incorporated the Bunker Hill and Sullivan Mining and Concentrating Company on 29 July 1887. John Hays Hammond was hired to manage the mine, and a new concentrator, The Old South Mill, became operational in 1891, capable of 150 tons per day. Hammond became president on 2 July 1891, followed by Nathaniel H. Harris on 15 June 1893, when company headquarters were located in San Francisco. William Henry Crocker, of Crocker National Bank, served as treasurer, in addition to being the major stockholder. When the mining boom began in the Coeur d'Alene, Idaho mining district, the area was lightly inhabited. The Bunker Hill and the Sullivan companies built a boarding house for miners in 1887. By 1894, the company employed 332 workers, and in the late 1890s, the company built single-family houses to attract family men. I ...
