Silver Mining In The United States
Silver mining in the United States began on a major scale with the discovery of the Comstock Lode in Nevada in 1858. The industry suffered greatly from the demonetization of silver in 1873 by the Coinage Act of 1873, known pejoratively as the "Crime of 73", but silver mining continues today. United States mines produced 1,170 tons of silver in 2014, 17% of the silver it used, while 63% of consumption was imported, from Mexico, Canada, Peru and Chile, and the remainder was derived from recycling. Three US mines had silver as their primary product, and 39 mines reported silver as a byproduct of gold and base metals production. Alaska was the country's leading silver-producing state, followed by Nevada and Idaho. Interest in silver mining has increased in recent years because of an increased price for the metal: the average silver price increased from $4.39 per troy ounce for the year 2001, to $13.45 per troy ounce for 2007. In 2011, silver prices rose to almost $49 per troy ounce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tombstone, Arizona
Tombstone is a city in Cochise County, Arizona, Cochise County, Arizona, United States, founded in 1879 by Prospecting, prospector Ed Schieffelin in what was then Pima County, Arizona, Pima County, Arizona Territory. It became one of the last boomtowns in the American frontier. The town grew significantly into the mid-1880s as the local Silver mining, mines produced $40 to $85 million in silver bullion, the largest productive silver district in Arizona. Its population grew from 100 to around 14,000 in less than seven years. It is best known as the site of the Gunfight at the O.K. Corral and draws most of its revenue from tourism. The city had a permanent population of 1,308, according to the 2020 United States census, 2020 census. History The town was established on Goose Flats, a mesa above the Goodenough Mine.

Calico, San Bernardino County, California
Calico is a ghost town and former mining town in San Bernardino County, California, United States. Located in the Calico Mountains of the Mojave Desert region of Southern California, it was founded in 1881 as a silver mining town, and was later converted into a county park named ''Calico Ghost Town''. Located off Interstate 15, it lies equidistant from Barstow and Yermo. Giant letters spelling ''CALICO'' are visible, from the highway, on the Calico Peaks behind it. Walter Knott purchased Calico in the 1950s, and rebuilt all but the five remaining original buildings to look as they did in the 1880s. Calico received California Historical Landmark #782, and in 2005 was proclaimed by then-Governor Arnold Schwarzenegger to be California's Silver Rush Ghost Town. History In 1881, four prospectors were leaving Grapevine Station (present-day Barstow, California) for a mountain peak to the northeast. After they described the peak as "calico-colored", the peak, the mountain range ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly Dolomite (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...

Paleozoic
The Paleozoic ( , , ; or Palaeozoic) Era is the first of three Era (geology), geological eras of the Phanerozoic Eon. Beginning 538.8 million years ago (Ma), it succeeds the Neoproterozoic (the last era of the Proterozoic Eon) and ends 251.9 Ma at the start of the Mesozoic Era. The Paleozoic is subdivided into six period (geology), geologic periods (from oldest to youngest), Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian. Some geological timescales divide the Paleozoic informally into early and late sub-eras: the Early Paleozoic consisting of the Cambrian, Ordovician and Silurian; the Late Paleozoic consisting of the Devonian, Carboniferous and Permian. The name ''Paleozoic'' was first used by Adam Sedgwick (1785–1873) in 1838 to describe the Cambrian and Ordovician periods. It was redefined by John Phillips (geologist), John Phillips (1800–1874) in 1840 to cover the Cambrian to Permian periods. It is derived from the Ancient Greek, Greek ''palaiós'' (π� ...

Cerro Gordo Mines
The Cerro Gordo Mines are a collection of abandoned mines located in Cerro Gordo in the Inyo Mountains, Inyo County, near Lone Pine, California. Mining operations spanned 1866 to 1957, producing high grade silver, lead, and zinc ore; and, more rarely, gold ore and copper ore. Some ore was smelted on site, but larger capacity smelters were eventually constructed along the shore of nearby Owens Lake. These smelting operations were the beginnings of the towns of Swansea and Keeler. Most of the metal ingots produced here were transported to Los Angeles, but transportation difficulties hindered the success of the mines. Mining of silver and lead peaked in the early 1880s, with a second mining boom producing zinc in the 1910s. During its peak, Cerro Gordo was home to some 4,700 people and the site is known as a California ghost town today. History Discovery of the silver ore is credited to Pablo Flores, who began mining and smelting operations near the summit of Buena Vista P ...

Gold
Gold is a chemical element; it has chemical symbol Au (from Latin ) and atomic number 79. In its pure form, it is a brightness, bright, slightly orange-yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal, a group 11 element, and one of the noble metals. It is one of the least reactivity (chemistry), reactive chemical elements, being the second-lowest in the reactivity series. It is solid under standard temperature and pressure, standard conditions. Gold often occurs in free elemental (native state (metallurgy), native state), as gold nugget, nuggets or grains, in rock (geology), rocks, vein (geology), veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as in electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tungsten
Tungsten (also called wolfram) is a chemical element; it has symbol W and atomic number 74. It is a metal found naturally on Earth almost exclusively in compounds with other elements. It was identified as a distinct element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternative name. The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all known elements, melting at . It also has the highest boiling point, at . Its density is 19.254 g/cm3, comparable with that of uranium and gold, and much higher (about 1.7 times) than that of lead. Polycrystalline tungsten is an intrinsically brittle and hard material (under standard conditions, when uncombined), making it difficult to work into metal. However, pure single-crystalline tungsten is more ductile and can be cut with a hard-steel hacksaw. Tungsten occurs in many alloys ...
