Daniel Cowan 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, Jacking 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 worke ...

Porphyry Copper
Porphyry copper deposits are copper ore bodies that are formed from 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 porphyritic intrusive rocks from which this deposit type derives its name. In later stages, circulating meteoric fluids may interact with the 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 introduction of steam shovels, the construction of railroads, and a surge in ...

Bingham Canyon, Utah
Bingham Canyon was a city formerly located in southwestern Salt Lake County, Utah, United States, in a narrow canyon on the eastern face of the Oquirrh Mountains. The Bingham Canyon area boomed during the first years of the twentieth century, as rich copper deposits in the canyon began to be developed, and at its peak the city had approximately 15,000 residents. The success of the local mines eventually proved to be the town's undoing, however: by the mid-twentieth century, the huge open-pit Bingham Canyon Mine began encroaching on the land of the community, causing residents to relocate. By the 1970s, almost the entirety of the town had been devoured by the mine, and the few remaining residents voted to disincorporate and abandon the community. No trace of Bingham Canyon remains today. History The geographic feature known as Bingham Canyon received its name from the location's two first settlers, the brothers Thomas and Sanford Bingham, who arrived in the canyon in 1848.

Nitro, West Virginia
Nitro is a city in Kanawha and Putnam counties in the State of West Virginia, named after a World War I era nitrocellulose plant built by the government. The population was 6,518 according to the 2021 Population estimates. 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. The city is known as "a Living Memorial to World WarI." Geography Nitro is located at (38.415281, -81.831249), primarily in Kanawha County. According to the United States Censu ...

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.

Steam Shovel
A steam shovel is a large steam-powered excavating machine designed for lifting and moving material such as 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-powered 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 which the boiler and movement engines were mounted. The shovel arm and driving engines ...

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 ...
