Carmen De Andacollo
Carmen de Andacollo is an open-pit copper mine in northern Chile next to the town of Andacollo and about 40 km southeast of the port city of Coquimbo. Teck Resources owns 90% of the mine while state-owned ENAMI owns the rest. The mine opened in 1996. In 2023 it produced 39,600 metric tons of copper concentrate. The ore mined belongs to the hypogene In ore deposit geology, hypogene processes occur deep below the Earth's surface, and tend to form deposits of primary minerals, as opposed to supergene processes that occur at or near the surface, and tend to form secondary minerals.

Consejo Minero
Consejo Minero (lit. Mining Council) is a guild grouping large mining companies active in Chile. According to Consejo Minero in 2025 its companies produce 94% of Chile's copper, 96% of its iron, 90% of its silver and 63% of its gold and lithium. Its members are Anglo American, BHP, CMP, Minera Centinela, Codelco, Compañía Minera Doña Inés de Collahuasi, El Abra (owned by Freeport-McMoRan and Codelco), Minera Escondida, Freeport-McMoRan, Glencore, Gold Fields, KGHM, Kinross, Lundin Mining, Pampa Norte, Minera Los Pelambres, Rio Tinto, South32, Sociedad Química y Minera and Teck Resources.

Surface Mines In Chile
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 inequivalent such formalizations that are all called ''surface'', sometimes with a qualifier such as algebraic surface, smooth surface or fractal surface. The concept of surface and its mathematical abstractions are both widely used in physics, engineering, computer graphics, and many other disciplines, primarily in representing the surfaces of ph ...

Open-pit Mines
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 (geology), 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 industrial sector, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Copper Mines In Chile
Copper is a chemical element; it has symbol Cu (from Latin ) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable, unalloyed metallic form. This means that copper is a native metal. This led to very early human use in several regions, from . Thousands of years later, it was the first metal to be smelted from sulfide ores, ; the first metal to be cast into a shape in a mold, ; and the first metal to be purposely alloyed with another metal, tin, to create bronze, .

Hypogene
In ore deposit geology, hypogene processes occur deep below the Earth's surface, and tend to form deposits of primary minerals, as opposed to supergene processes that occur at or near the surface, and tend to form secondary minerals. At great depth the pressure is high, and water can remain liquid at temperatures well above 100 °C. Hot aqueous solutions originating from magmas, deep sedimentary basins, or areas of elevated geothermal gradients can contain metals and other ions derived from the magma itself or from leaching of sedimentary, igneous, or metamorphic rocks. Hypogene deposition processes include crystallization from the hot aqueous solutions flowing through the Earth's crust, driven by temperature and pressure gradients, as well as topographic, orogenic, and structural changes and/or controls.The Encyclopedia of Gemstones and Minerals (1991).

Copper Concentrate
Copper extraction is the multi-stage process of obtaining 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. The copper smelters with the highest production capacity (metric tons of copper yearly) lie in China, Chile, India, Germany, Japan, Peru and Russia. China alone has over half of the world's production capacity and is also the world's largest consumer of refined copper. Precious metals and sulfuric acid are often valuable by-products of copper refining. Arsenic is the main type of impurity found in copper concentrates to enter smelting facilities. There has been an increase in arsenic in copper concentrates over the years since shallow, low-arsenic copper deposits have been progressively depleted.

Coquimbo
Coquimbo is a port List of cities in Chile, city, Communes of Chile, commune and capital of the Elqui Province, located on the Pan-American Highway, in the Coquimbo Region of Chile. Coquimbo is situated in a valley south of La Serena, Chile, La Serena, with which it forms Greater La Serena with more than 400,000 inhabitants. The commune spans an area around the harbor of . The average temperature in the city lies around , and precipitation is low. History The area was originally occupied by indigenous people, who used it as a settlement and for fishing purposes. The natural harbor in Coquimbo was taken over by Pedro de Valdivia from Spain in 1550. In 1879 it was recognized as a town. The city was on the main path of totality of the Solar eclipse of July 2, 2019. English settlement Coquimbo was first mentioned in the English speaking world when Charles Darwin visited during his voyage on HMS Beagle, stopping in the town on 14 May 1835 describing the town as "remarkable for nothing ...

Chile
Chile, officially the Republic of Chile, is a country in western South America. It is the southernmost country in the world and the closest to Antarctica, stretching along a narrow strip of land between the Andes, Andes Mountains and the Pacific Ocean.

Andacollo
Andacollo (, from quechua a''nta,'' copper, gold; ''coya,'' queen) is a city and commune in the Elqui Province, Coquimbo Region, Chile. It is the central town of a mining district dominated by medium-scale mining. There are gold placers and gold mineralizations within felsic volcanic rock in its vacinities. The copper mine Carmen de Andacollo lies next to the town and most of workers live in the town. History Andacollo is a copper and gold mining city located in the semi-arid mountains of the Norte Chico. It was founded in 1891. The town was subject to gold rush in the early 1930s when there was a large inflow of gold miners exploiting local placer deposits. While gold mining declined in the late 1930s, around 1935 Andacollo produced as much as 43% of all placer gold of Chile causing a shortage of water needed for processing. Several legends are told about the name of the city. Some say that it comes from the Quechua ''Anta-Goya'' which means cobre-reina (copper queen) ...
