Gold Mining In Chile
The amount of gold mined in Chile has fluctuated in the 2010–2023 period from a high of 50,852 kg in 2013 to a low of 30,907 kg in 2022. Also in the same period 36% to 72% of the gold produced annually in Chile was a by-product of copper mining. The share of medium and small-scale mining in gold production in Chile has dropped from an average of 45% for the 2003–2005 period to 9% in 2023. Most of the economically viable gold deposits in Chile belong to two types of deposits; high-sulfidation epithermal and porphyry type. The bulk of these deposits formed in the last 66 millions years (Cenozoic) in connection to magmatic activity in the Andes. Gold from iron oxide copper gold ore deposits (IOCG), from mesothermal deposits, or of Mesozoic age (formed 66 to 252 million years ago) may in some cases be recurrent geological features but lack often large concentrations to make them profitable. Almost all valuable non-placer gold in Chile occur in the northern half of the country an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andacollo Gold Mine
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) ...

El Indio Gold Belt
The El Indio Gold Belt is a mineral-rich region spanning the border between Chile and Argentina that contains large quantities of gold, silver and copper. On both sides of the border the belt is located within the Andes. The El Indio mine within the district was the first modern mine in Chile to produce gold as its main product. In Chile the main precious metal containing mineral is enargite. The El Indio belt is bordered in the north by another gold-silver mining district known as the Frontera District. Rodalquilarite, alunite and poughite are some of the minerals present in the area. The deposits of the belt formed during the Late Miocene period. The world's largest gold mining company, Barrick Gold, used to be the only foreign company heavily invested in the region however more recently a number of other companies have begun exploratory activity. History In Chile the district was first officially recognized in 1975 and operated in 1979. El Indio, the main mine in the are ...

Underground Mining
Mining is the extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation or restoration of the land after the mine is closed. Mining materials are often obtained from ore bodies, lodes, veins, seams, reefs, or placer deposits. The explo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Open-pit Mining
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] |
Cordillera De Nahuelbuta
The Nahuelbuta Range or Cordillera de Nahuelbuta () is a mountain range in Bio-Bio and Araucania Region, southern Chile. It is located along the Pacific coast and forms part of the larger Chilean Coast Range. The name of the range derives from the Mapudungun words ''nahuel'' (jaguar) and ''futa'' (big). Much of Cordillera Nahuelbuta is covered by pine and eucalyptus monoculture plantations. Some areas of plantations were ones that were being subject to severe soil erosion before the plantations while others were native forest that was cleared with fire to establish plantations. The bulk of the plantations were established in the 1970s, 1980s and 1990s. At Villa las Araucarias in Cordillera Nahuelbuta there is a small remnant of some of the southernmost ''Araucaria araucana'' trees in the Chilean Coast Range. By 1950 there were 1000 ha of ''Araucaria araucana'' forest around this site, but by 2016 only 40 ha remained. Historically Cordillera de Nahuelbuta and its surrounding ...

Illegal Mining In Chile
Illegal mining is a concern in Chile. As of 2025 it was considered to be on the rise but still far below the levels of neighbouring countries like Brazil, Colombia, Ecuador and Peru. In 2024 there were 20 formal complaints of illegal mining before the National Geology and Mining Service. There is as of 2025 no large-scale illegal mining in Chile. Illegal mining is greatly overrepresented relative to legal mining in deadly accidents in Chile. The fact that most small-scale mining in Chile focus on copper, which means handling large volumes difficult to smuggle or hide has been thought to be a contributing factor to the low levels of illegal mining. The term '' chucullero'' is sometimes used pejoratively for artisan miners known as ''pirquineros'' who carry out illegal mining, but this is not always the case as ''chucullero'' also refers more generally to any ''pirquinero'' specialized in precious metals, mostly gold. Some communes where illegal mining have been reported in the 20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
