Crisson Mine
Crisson Mine was a gold mine in Lumpkin County, Georgia, USA, located just east of Dahlonega. Like many mines in the area, the property probably started as a placer mine during the Georgia Gold Rush. Once the placer deposits had been exhausted, an open pit gold mine was established in 1847 and commercial operations continued until the early 1980s. A small stamp mill was also established here. Much of the gold used for the gold leaf dome of the Georgia State Capitol was mined at this mine, which was among the most productive mines in the Georgia Gold Belt. The mine is located just north of the site of the Consolidated Mine, which is itself north of the Calhoun Mine. In 1969, the owners of Crisson Mine opened to the public to allow tourists to pan for gold. The ore sold for panning is still crushed by the stamp mill, which is now well over 100 years old. It is likely that panning the ore provided at the mine will yield small amounts of gold (flakes, specks, small nuggets). E ...

Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as 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 most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is ...

Georgia Gold Belt
The largest quantities of gold found in the eastern United States were found in the Georgia Gold Belt, extending from eastern Alabama to Rabun County, Georgia. The biggest concentration of gold was found in White, Lumpkin, and northern Cherokee counties in Georgia. The gold in the Georgia Gold Belt was close to 24 karat (100%) purity. Most of the gold was found in eroded rock ( saprolite) and mixed in with quartz. Besides placer deposits of gold, and gold bearing quartz in weathered rock, gold also occurs in quartz veins. The most profitable veins, in the Dahlonega District, occur in the contact zone between mica-schists and granite or diorite.Eckel, E.C. 1902, Gold and Pyrite Deposits of the Dahlonega District, Georgia, in Contributions to Economic Geology, USGS Bulletin No. 213, Washington: Government Printing Office The discovery of gold in the Georgia Gold Belt in 1828 led to the Georgia Gold Rush.

Surface Mines In The United States
A surface, as the term is most generally used, is the outermost or uppermost layer of a physical object or space. It is the portion or region of the object that can first be perceived by an observer using the senses of sight and touch, and is the portion with which other materials first interact. The surface of an object is more than "a mere geometric solid", but is "filled with, spread over by, or suffused with perceivable qualities such as color and warmth". The concept of surface has been abstracted and formalized in mathematics, specifically in geometry. Depending on the properties on which the emphasis is given, there are several non equivalent such formalizations, that are all called ''surface'', sometimes with some qualifier, such as algebraic surface, smooth surface or fractal surface. The concept of surface and its mathematical abstraction are both widely used in physics, engineering, computer graphics, and many other disciplines, primarily in representing the surfaces ...

Calhoun Mine
The Calhoun Mine is perhaps the oldest and best-known mine in Lumpkin County, Georgia. When gold was discovered in Lumpkin County in 1828, which led to the Georgia Gold Rush in 1829, it was discovered on owned by Robert Obar. After at least two intermediary sales, the land was purchased by US Senator, Senator John C. Calhoun of South Carolina, who was also the 7th Vice President of the United States. Calhoun started a mining company to mine the land and later allowed his son-in-law Thomas Green Clemson, the founder of Clemson University, to manage it. The ore deposit was a very rich deposit and, according to an 1856 letter from Clemson to his brother-in-law, was still producing significant quantities of gold nearly 30 years after its initial discovery on the land. This mine - along with the Consolidated Mine and the Loud Mine - were some of the most productive mines in the Georgia Gold Belt. In 1879, the Calhoun Mine passed from the Calhoun family. In 1939, after the deposits at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Consolidated Mine
The Consolidated Mine was a gold mine in Lumpkin County, Georgia, United States, just east of Dahlonega. Like most of the area around Dahlonega, the placer mining on the land on which the mine is located probably started during the Georgia Gold Rush. By 1880, the placer deposits were exhausted and the land was down to hard rock. Gold was soon discovered in a huge quartz vein system, and mined. "The richest acre" was mined deep into the ground, and the resulting shaft became known as the "Glory Hole.” After an interruption of operations at the mine, a group of investors purchased about 7,000 acres (28 km2) of land around the discovery site and formed the Dahlonega Consolidated Gold Mining Co. in 1895. After constructing the largest stamp mill east of the Mississippi River at the Consolidated Mine property, the Mining Co. folded in 1906. The mine's lower workings became flooded and lay dormant until seventy-five years later, when the site came under new ownership. There is ...

Georgia State Capitol
The Georgia State Capitol is an architecturally and historically significant building in Atlanta, Georgia, United States. The building has been named a National Historic Landmark which is listed on the National Register of Historic Places. As the primary office building of Georgia's government, the capitol houses the offices of the governor, lieutenant governor, and secretary of state on the second floor, chambers in which the General Assembly, consisting of the Georgia State Senate and Georgia House of Representatives, meets annually from January to April. The fourth floor houses visitors' galleries overlooking the legislative chambers and a museum located near the rotunda in which a statue of ''Miss Freedom'' caps the dome. History The capitol site was occupied previously by the first Atlanta City Hall. To encourage the state government to relocate the capital city to rapidly growing and industrialized Atlanta from rural Milledgeville, the city donated the site. The 1877-7 ...

Lumpkin County, Georgia
Lumpkin County is a county located in the north central portion of the U.S. state of Georgia. As of the 2020 census, the population was 33,488. Its county seat is Dahlonega. History This area was settled by the Cherokee, who also occupied areas of what became delimited as southeastern Tennessee and western North Carolina. Lumpkin County was created on December 3, 1832. The county was named for Wilson Lumpkin, who at the time was Governor of Georgia. Lumpkin's daughter, Martha Wilson Lumpkin Compton, was the namesake of the town named Marthasville, the early-1840s name for Atlanta in Fulton County; this was designated as the capital of the state after the Civil War. In the 1830s, gold was discovered in the county near Auraria, leading to a rush of miners and development. The U.S. government established a mint in Dahlonega, operating for 23 years until the outbreak of the American Civil War. State contractors later acquired gold from Lumpkin County to gild the dome of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stamp Mill
A stamp mill (or stamp battery or stamping mill) is a type of mill machine that crushes material by pounding rather than grinding, either for further processing or for extraction of metallic ores. Breaking material down is a type of unit operation. Description A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft. As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam. Each one frame and stamp set is sometimes called a "battery" or, confusingly, a "stamp" and mills are sometimes categorised by how many stamps they have, i.e. a "10 stamp mill" has 10 sets. They usually are arranged linearly, but when a mill is enlarged, a new line of them may be constructed rather than extending the line. Abandoned mill sites (as ...

Open Pit
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburden is relatively thin or the material of interest is structurally unsuitable for tunnelling (as would be the case for cinder, sand, and gravel). In contrast, minerals that have been found underground but are difficult to retrieve due to hard rock, can be reached using a form of underground mining. To create an open-pit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting eac ...
