Ore is natural rock or sediment that contains one or more valuable minerals concentrated above background levels, typically containing metals, that can be mined, treated and sold at a profit. The grade of ore refers to the concentration of the desired material it contains. The value of the metals or minerals a rock contains must be weighed against the cost of extraction to determine whether it is of sufficiently high grade to be worth mining and is therefore considered an ore. A complex ore is one containing more than one valuable mineral.
Bart Township is a township in southeastern Lancaster County, Pennsylvania, United States. At the 2020 census, the population was 3,181, up from 3,094 at the 2010 census.
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.
Land rehabilitation as a part of environmental remediation is the process of returning the land in a given area to some degree of its former state, after some process has resulted in its damage. Many projects and developments will result in the land becoming degraded, for example mining, farming and forestry.
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper ores consists of a series of physical, chemical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

First Quantum Minerals is a Canadian-based mining and metals company whose principal activities include mineral exploration, development and mining. Its main product is copper, which accounts for 80% of revenues as of 2016.
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.
The Bingham Canyon Mine, more commonly known as Kennecott Copper Mine among locals, is an open-pit mining operation extracting a large porphyry copper deposit southwest of Salt Lake City, Utah, in the Oquirrh Mountains. The mine is the largest man-made excavation, and deepest open-pit mine in the world, which is considered to have produced more copper than any other mine in history – more than 19,000,000 short tons. The mine is owned by Rio Tinto Group, a British-Australian multinational corporation. The copper operations at Bingham Canyon Mine are managed through Kennecott Utah Copper Corporation which operates the mine, a concentrator plant, a smelter, and a refinery. The mine has been in production since 1906, and has resulted in the creation of a pit over 0.75 miles (1,210 m) deep, 2.5 miles (4 km) wide, and covering 1,900 acres. It was designated a National Historic Landmark in 1966 under the name Bingham Canyon Open Pit Copper Mine. The mine experienced a massive landslide in April 2013 and a smaller slide in September 2013.
On October 2, 2006, a shooting occurred at the West Nickel Mines School, an Amish one-room schoolhouse in the Old Order Amish community of Nickel Mines, a village in Bart Township, Pennsylvania. Gunman Charles Carl Roberts IV took hostages and shot ten girls, killing five, before committing suicide in the schoolhouse. The emphasis on forgiveness and reconciliation in the Amish community's response was widely discussed by the national media. The West Nickel Mines School was later demolished, and a new one-room schoolhouse, the New Hope School, was built at another location.
Georgetown is an unincorporated community and census-designated place (CDP) in Bart Township, Lancaster County, Pennsylvania, United States. As of the 2010 census, the population was 1,022. Georgetown has a post office for P.O. boxes that is called Bart and has the ZIP code of 17503. Otherwise, the CDP is divided into three ZIP code areas for more distant communities.
The Kanichee Mine, also less commonly known as the Ajax Mine, is an abandoned base metal and precious metal mine, located in the Temagami region of northeastern Ontario, Canada. It is near the small unincorporated community of Temagami North, accessed by the Kanichee Mine Road from Highway 11. The Kanichee Mine zone has been explored and mined discontinuously from as early as 1910. During the 20th century, it operated and closed down at least three times, with the most recent being from 1973 to 1976. To date, the discontinuous operation of Kanichee Mine has produced 4.2 million pounds of metal.
Creighton Mine is an underground nickel, copper, and platinum-group elements (PGE) mine. It is presently owned and operated by Vale Limited in the city of Greater Sudbury, Ontario, Canada. Open pit mining began in 1901, and underground mining began in 1906. The mine is situated in the Sudbury Igneous Complex (SIC) in its South Range geologic unit. The mine is the source of many excavation-related seismic events, such as earthquakes and rock burst events. It is home to SNOLAB, and is currently the deepest nickel mine in Canada. Expansion projects to deepen the Creighton Mine are currently underway.
In the United States, copper mining has been a major industry since the rise of the northern Michigan copper district in the 1840s. In 2017, the US produced 1.27 million metric tonnes of copper, worth $8 billion, making it the world's fourth largest copper producer, after Chile, China, and Peru. Copper was produced from 23 mines in the US. Top copper producing states in 2014 were Arizona, Utah, New Mexico, Nevada, and Montana. Minor production also came from Idaho, and Missouri. As of 2014, the US had 45 million tonnes of known remaining reserves of copper, the fifth largest known copper reserves in the world, after Chile, Australia, Peru, and Mexico.
In Michigan, copper mining became an important industry in the 19th and early 20th centuries. Its rise marked the start of copper mining as a major industry in the United States.
The mining industry of Botswana has dominated the national economy of Botswana since the 1970s. Diamond has been the leading component of the mineral sector since large-scale diamond production began in 1972 by Debswana. Most of Botswana's diamond production is of gem quality, resulting in the country's position as the world's leading producer of diamond by value. Copper, gold, nickel, coal and soda ash production also has held significant, though smaller, roles in the economy.
The mineral industry of Russia is one of the world's leading mineral industries and accounts for a large percentage of the Commonwealth of Independent States' production of a range of mineral products, including metals, industrial minerals, and mineral fuels. In 2005, Russia ranked among the leading world producers or was a significant producer of a vast range of mineral commodities, including aluminum, arsenic, cement, copper, magnesium compounds and metals, nitrogen, palladium, silicon, nickel and vanadium.
Ahtium was a Finnish mining company that operated the Talvivaara nickel mine from the company's establishment in 2004 until the mining business was sold to the state-owned Terrafame in 2015.
The Pahaquarry Copper Mine is an abandoned copper mine located on the west side of Kittatinny Mountain presently in Hardwick Township in Warren County, New Jersey in the United States. Active mining was attempted for brief periods during the mid-eighteenth, mid-nineteenth, and early twentieth centuries but was never successful despite developments in mining technology and improving mineral extraction methods. Such ventures were not profitable as the ore extracted proved to be of too low a concentration of copper. This site incorporates the mining ruins, hiking trails, and nearby waterfalls, and is located within the Delaware Water Gap National Recreation Area and administered by the National Park Service. It was added to the National Register of Historic Places in 1980 as a contributing property to the Old Mine Road Historic District.
A nickel mine is a mine that produces nickel. Some mines produce nickel primarily, while some mines produce nickel as a side-product of some other metal that has a higher concentration in the ore.
