Bunker Hill Mine And Smelting Complex
The Bunker Hill Mine and Smelting Complex (colloquially the Bunker Hill smelter) was a large smelter located in Kellogg, Idaho, in the Coeur d'Alene Basin. When built, it was the largest smelting facility in the world.National Research Council, 200516/ref> It is located in what became known as the Silver Valley of the Coeur d'Alene Basin, an area for a century that was a center of extensive silver and other metal mining and processing. This resulted in extensive contamination of water, land and air, endangering residents including the Coeur d'Alene Tribe, which had traditionally depended on fish from the waterways as part of its subsistence. In 1983 the United States Environmental Protection Agency added this area to the National Priorities List as a Superfund site for investigation and cleanup. In 1991 the Coeur d'Alene Tribe filed suit against the mining companies for damages and cleanup costs; they were joined by the federal government in 1996 and the state of Idaho in 2011. ...

Silver Valley (Idaho)
The Silver Valley is a region in the northwest United States, in the Coeur d'Alene Mountains in northern Idaho. It is noted for its mining heritage, dating back to the 1880s. Geography Silver Valley is a narrow valley about in length, east of the city of Coeur d'Alene. The South Fork of the Coeur d'Alene River flows through the valley and Interstate 90 traverses the valley between Fourth of July Pass to the west and Lookout Pass on the Montana border. Several towns are located in the valley, all in Shoshone County. These include (from west to east) Pinehurst, Smelterville, Kellogg, Wardner, Osburn, Silverton, Wallace, and Mullan. The Silver Valley has also been referred to as the Coeur d'Alene Valley and the Coeur d'Alene Mining District. Geology The Coeur d'Alene (Silver Valley) Mining District is located in Proterozoic metasediments. The mined portion of the stratigraphic column in the Silver Valley, known as the Belt series, can be divided into six main ...

Hoist (mining)
In underground mining a hoist or winder is used to raise and lower conveyances within the mine shaft. Modern hoists are normally powered using electric motors, historically with direct current drives utilizing Ward Leonard control machines and later solid-state converters ( thyristors), however modern large hoists use alternating current drives that are variable frequency controlled. There are three principal types of hoists used in mining applications: Drum hoist Drum hoists are the most common type of hoist used in North America, South Africa and South America. When using a drum hoist the hoisting cable is wound around the drum when the conveyance is lifted. Single-drum hoists can be used in smaller applications, however double-drum hoists easily allow the hoisting of two conveyances in balance (i.e. one skip being lifted while a second skip is being lowered). Drum hoists are mounted on concrete slabs within a hoistroom, the hoisting ropes run from the drum, up to the top ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adit
An adit (from Latin ''aditus'', entrance) is an entrance to an underground mine which is horizontal or nearly horizontal, by which the mine can be entered, drained of water, ventilated, and minerals extracted at the lowest convenient level. Adits are also used to explore for mineral veins. Construction Adits are driven into the side of a hill or mountain, and are often used when an ore body is located inside the mountain but above the adjacent valley floor or coastal plain. In cases where the mineral vein outcrops at the surface, the adit may follow the lode or vein until it is worked out, in which case the adit is rarely straight. The use of adits for the extraction of ore is generally called drift mining. Adits can only be driven into a mine where the local topography permits. There will be no opportunity to drive an adit to a mine situated on a large flat plain, for instance. Also if the ground is weak, the cost of shoring up a long adit may outweigh its possible advant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerial Tramway
An aerial tramway, sky tram, cable car, ropeway, aerial tram, telepherique, or seilbahn is a type of aerial lift which uses one or two stationary ropes for support while a third moving rope provides propulsion. With this form of lift, the grip of an aerial tramway cabin is fixed onto the propulsion rope and cannot be decoupled from it during operations. In comparison to gondola lifts, aerial tramways generally provide lower line capacities and higher wait times. Terminology Because of the proliferation of such systems in the Alpine regions of Europe, the French and German names, ''téléphérique'' and ''Seilbahn'', respectively, are often also used in an English language context. ''Cable car'' is the usual term in British English, as in British English the word ''tramway'' generally refers to a railed street tramway while in American English, ''cable car'' may additionally refer to a cable-pulled street tramway with detachable vehicles; e.g., San Francisco's cable ...

John Hays Hammond
John Hays Hammond (March 31, 1855 – June 8, 1936) was an American mining engineer, diplomat, and philanthropist. He amassed a sizable fortune before the age of 40. An early advocate of deep mining, Hammond was given complete charge of Cecil Rhodes' mines in South Africa and made each undertaking a financial success. He was a main force planning and executing the Jameson Raid in 1895. It was a fiasco and Hammond, along with the other leaders of the Johannesburg Reform Committee, was arrested and sentenced to death. The Reform Committee leaders were released after paying large fines, but like many of the leaders, Hammond escaped Africa for good. He returned to the United States, became a close friend of President William Howard Taft, and was appointed a special ambassador. At the same time, he continued to develop mines in Mexico and California and, in 1923, he made another fortune while drilling for oil with the Burnham Exploration Company. Early life Hammond was the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Smelted
Smelting is a process of applying heat to ore, to extract a base metal. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind. The reducing agent is commonly a fossil fuel source of carbon, such as coke—or, in earlier times, charcoal. The oxygen in the ore binds to carbon at high temperatures due to the lower potential energy of the bonds in carbon dioxide (). Smelting most prominently takes place in a blast furnace to produce pig iron, which is converted into steel. The carbon source acts as a chemical reactant to remove oxygen from the ore, yielding the purified metal element as a product. The carbon source is oxidized in two stages. First, the carbon (C) combusts with oxygen (O2) in the air to produce carbon monoxide (CO). Secon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burke, Idaho
Burke is a ghost town in Shoshone County, Idaho, United States, established in 1887. Once a thriving silver, lead and zinc mining community, the town saw significant decline in the mid-twentieth century after the closure of several mines. In its early years, Burke was home to the Hercules silver mine, the owners of which were implicated in the Idaho mining wars of 1899. Both the Hecla and Star mines also operated out of Burke, and the town was a significant site during the 1892 Coeur d'Alene labor strike. Burke's location within the narrow Burke Canyon resulted in unique architectural features, such as a hotel built above the railway and Canyon Creek, with the train track running through a portion of the hotel lobby. After several natural disasters and years of decline in the mid-twentieth century, Burke mining operations finally ceased in 1991 with the closing of the Star mine. In 2002, about 300 people lived in or nearby Burke Canyon, though Burke itself had no residents. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
