Ely, Nevada
Ely (, ) is the largest city and county seat of White Pine County, Nevada, United States. Ely was founded as a stagecoach station along the Pony Express and Central Overland Route. In 1906 copper was discovered. Ely's mining boom came later than the other towns along US 50. The railroads connecting the transcontinental railroad to the mines in Austin, Nevada and Eureka, Nevada have long been removed, but the railroad to Ely is preserved as a heritage railway by the Nevada Northern Railway and known as the ''Ghost Train of Old Ely''. As of the 2020 census, the population was 3,924. History In 1878, Vermont resident J. W. Long came to White Pine County and soon set up a camp known as "Ely", after discovering gold. The name "Ely" has been credited to several possible origins: Long's hometown of Ely, Vermont; a New York Congressman with the surname Ely, who sent Long as a representative according to local historians; Smith Ely, a Vermont native who financed one of the cit ...

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 ...

Wells, Nevada
Wells is a small city in Elko County, in northeast Nevada in the western United States. The population was 1,292 at the 2010 census. Wells is located at the junction of Interstate 80 and U.S. Route 93, approximately east of Elko and is part of the Elko micropolitan area. History The site of Wells began as a place called Humboldt Wells along the trail to California. It was subsequently founded as a railroad town along the original Transcontinental Railroad, and was once a stopover for passenger trains. The Humboldt River has its source in springs and a swampy area just west of the city that today is called Humboldt Wells. In the late 19th century, Humboldt Wells was burning down, and in a frantic plea for help, a telegraph was sent that said, "Wells is burning". After this the town was rebuilt and simply referred to as 'Wells'. A magnitude 6.0 earthquake occurred near Wells at 6:16 A.M. on February 21, 2008. Because of its proximity to the epicenter, Wells experienced signifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pioche, Nevada
Pioche is an unincorporated town in Lincoln County, Nevada, United States, approximately northeast of Las Vegas. U.S. Route 93 is the main route to Pioche and bypasses the town center just to the east, with Nevada State Route 321 and Nevada State Route 322 providing direct access. Its elevation is above sea level. Pioche is the county seat of Lincoln County.

By the early 1870s, Pioche had grown larger, to become one of the most important silver-mining towns in Nevada ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delta, Utah
Delta is the largest city in Millard County, Utah, United States. It is located in the northeastern area of Millard County along the Sevier River and is surrounded by farmland. The population was 3,436 at the 2010 census. History Delta was originally a railroad switch called Aiken. In 1905 Aiken was renamed Melville when Millard County began plans to set up irrigation and a dam. People purchased land for 50 cents an acre as long as they agreed to develop a 40-acre lot. The name was changed again because of the similarities between Melville and Millville, another town in Utah. The name was changed on 12 May 1908 to Burtner. The name was finally changed to Delta on May 11, 1911. The name is quite fitting as the area was a delta of the Sevier River. Topaz Relocation Camp During World War II, after the attack on Pearl Harbor, tens of thousands of Japanese-Americans were gathered up and placed in 10 incarceration camps to protect military installations from espionage.

BHP Nevada Railroad
The BHP Nevada Railroad was a shortline railroad that operated in Nevada from 1996 to 1999. BHP acquired the line from Nevada Northern Railway. Constructed by Utah Construction Company in 1908, the railroad hauled copper ore concentrate from BHP's concentrator at Riepetown to Shafter, Nevada. At Shafter the railroad interchanged with the Union Pacific and the ore continued to BHP's smelter at San Manuel, Arizona. BHP is an Australian-based company that took over Magma Copper, the owner of the Robinson Mine at Ruth, Nevada, in January 1996. The line ran south from a connection with the Union Pacific at Shafter to Ely. Locomotives The BHP Nevada Railroad used five former Southern Pacific Railroad EMD SD9 locomotives built between 1954 and 1956 to operate over the line. They were numbered #201 – 205. For switching and local operations the railroad used two GE 70-ton switchers from the Santa Maria Valley Railroad. BHP also had one ALCO RS-3. The switchers were also b ...

Ruth, Nevada
Ruth is a census-designated place (CDP) in White Pine County, Nevada, United States. Founded in 1903, it had a population of 440 at the 2010 census. Ruth was built as a company town for the adjacent Robinson Mine, a large open-pit copper mine, which is still in operation as of 2022. Demographics History Ruth began as a settlement for workers of the White Pine Copper Company in 1903. It derived its name from the Ruth mining claim which was named for Ruth McDonald, daughter of the original owner of the mining claim. With the opening Nevada Northern Railway in the year 1906 copper production began to boom. In 1905, Daniel C. Jackling "evaluated a low-grade copper prospect", which he turned into "an impressive open-pit and satellite cave (the Veteran Mine)." Jackling went on to become president of the Nevada Consolidated Copper Company. By 1910 the settlement was already established a small distance from the first site. Ruth was a company town for the Nevada Consolidated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robinson Mine
The Robinson Mine is a porphyry copper deposit located at Ruth, White Pine County, Nevada, in the Egan Range, west of Ely. The mine comprises three large open pits: Liberty, Tripp-Veteran and Ruth. The ore is extracted using conventional surface methods, and is then processed into a copper-gold concentrate, and a molybdenum concentrate in a concentrating plant. Since 2012 the mine has been owned and operated by Polish copper miner KGHM Polska Miedź Large-scale copper mining began in the district in 1907 and, with some hiatuses and several changes of ownership, continues in 2019. Production from 1908 to 1978 was more than 4 billion pounds (1.5 million tonnes) of copper and of gold, and 2018 annual production of 106 million pounds (48,000 tonnes) of copper and of gold. Published ore reserves at Robinson as of end of 2017 were of copper. Current plans are for the mine to operate until 2022 before closure and reclamation.

Heap Leaching
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ore, whereas ''in situ'' mining lacks these liners and pulls pregnant solution up to obtain the minerals. Heap leaching is widely used in modern large-scale mining operations as it produces the desired concentrates at a lower cost compared to conventional processing methods such as flotation, agitation, and vat leaching. Additionally, dump leaching is an essential part of most copper mining operations and determines the quality grade of the produced material along with other factors Due to the profitability that the dump leaching has on the mining process, i.e. it can contribute substanti ...
