Daniel C. Jackling
Daniel Cowan Jackling (August 14, 1869 – March 13, 1956), was an American mining and metallurgical engineer who pioneered the exploitation of low-grade porphyry copper ores at the Bingham Canyon Mine, Utah. Biography Early life Born near Appleton City, Missouri, he was an orphan at the age of two. Raised for a while by an aunt, Jackling eventually had to pass from family to family but finished eighth grade by the age of sixteen and then enrolled in the Normal School at Warrensburg, Missouri. Starting in 1889, Daniel Jackling was educated in the mining and metallurgy disciplines at the Missouri School of Mines in Rolla, Missouri, now known as Missouri University of Science and Technology, eventually earning a BS degree. From 1891 until 1893 he taught chemistry and metallurgy as an assistant professor. Career Jackling worked at the Cripple Creek & Victor Gold Mine from 1893 until 1895, first as a miner, then as a millman and metallurgist. Starting in 1896, Jackling ...

Porphyry Copper
Porphyry copper deposits are copper ore bodies that are formed from hydrothermal circulation, hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the deposit itself. Predating or associated with those fluids are vertical dikes of porphyry (geology), porphyritic intrusive rocks from which this deposit type derives its name. In later stages, circulating meteoric water, meteoric fluids may interact with the magmatic water, magmatic fluids. Successive envelopes of hydrothermal alteration typically enclose a core of disseminated ore minerals in often stockwork-forming hairline fractures and veins. Because of their large volume, porphyry orebodies can be economic from copper concentrations as low as 0.15% copper and can have economic amounts of by-products such as molybdenum, silver, and gold. In some mines, those metals are the main product. The first mining of low-grade copper porphyry deposits from large open pits coincided roughly with the in ...

Nitro, West Virginia
Nitro is a city in Kanawha and Putnam counties in the U.S. state of West Virginia. It takes its name from a World War I era nitrocellulose plant. The population was 6,618 according to the 2020 census. It is part of the Charleston metropolitan area. History Nitro was incorporated in 1932 by Circuit Court. The name Nitro derives from nitrocellulose, the main ingredient in smokeless gunpowder. The Nitro area was to be the American ammunition production facility during World WarI. Daniel C. Jackling "supervised the construction and operation" of the plant, which by the time of the armistice "was producing one hundred thousand pounds of high explosives per day." Its name was selected by the United States government because of the establishment there, during World WarI, of a large federal plant for the manufacture of explosives.

Alaska-Gastineau Mine
The Alaska-Gastineau Mine (alternate: Perseverance Mine) was a gold mine in Perseverance, about east of Juneau, Alaska, USA. It was briefly the largest gold mine in the world. The mine was operated by the Alaska-Gastineau Mining Company. Geography The Alaska-Gastineau Mine was located within the Silver Bow Basin. Its concentrating plant was situated near Thane. The mine had a shaft running through Mount Roberts that reached the Perseverance Mine near Gold Creek. It adjoined the Alaska-Juneau Mine. The mine's low-grade ore is situated on a mountain above the Gastineau Channel. Its ore body covered approximately , more than in length, with of tunnels and crosscuts. According to Jackling, the block of ore had at least 100,000,000 tons above sea level. The property consisted of a group of claims whose lode system covered . It was operated on a 6,000-ton daily capacity. History The mine's large scale development began in 1912. In 1913, while it was under construction, Emile ...

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 Consolidat ... [...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.

Steam Shovel
A steam shovel is a large steam engine, steam-powered excavating machine designed for lifting and moving material such as Rock (geology), rock and soil. It is the earliest type of power shovel or excavator. Steam shovels played a major role in public works in the 19th and early 20th century, being key to the construction of railroads and the Panama Canal. The development of simpler, cheaper Diesel fuel, diesel, gasoline and Electricity, electric Power shovel, shovels caused steam shovels to fall out of favor in the 1930s. History Origins and development Grimshaw of Boulton & Watt devised the first steam-powered excavator in 1796. In 1833 William Brunton patented another steam-powered excavator which he provided further details on in 1836. The steam shovel was invented by William Otis, who received a patent for his design in 1839. The first machines were known as 'partial-swing', since the boom could not rotate through 360 degrees. They were built on a railway chassis, on whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 that extracts rock or minerals from the earth. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface where the overburden is relatively thin. In contrast, deeper mineral deposits can be reached using underground mining. Open-pit mining is considered one of the most dangerous sectors in the industrial world. It causes significant effects to miners' health, as well as damage to the ecological land and water. Open-pit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths. Additionally, open-pit produces harmful pollutants depending on the type of mineral being mined, and the type of mining process being used. Extraction Miners typically drill a series of test holes to locate an underground ore body. From ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
