Dominga Sotomayor
Dominga is a copper and iron ore prospect and mine project in northern Chile. The ores of Dominga are emplaced in volcanic and plutonic rocks of the Punta del Cobre Formation and the "Dioritic Complex" respectively. The Dominga mine project has been controversial because of an alleged conflict of interest involving former president Sebastián Piñera and Carlos Alberto Délano Carlos may refer to: Places ;Canada * Carlos, Alberta, a locality ;United States * Carlos, Indiana, an unincorporated community * Carlos, Maryland, a place in Allegany County * Carlos, Minnesota, a small city * Carlos, West Virginia ;Elsewhere ... a local magnate and friend of Piñera. The purchase deal of Dominga included a clause for the last payment to be done only if no new environmental protection area was created near the mine, leading to a conflict of interest for Piñera. The details of the agreement became only known with the Pandora Papers in 2021. The project has also been criticized on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) 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 metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Iron
Iron () is a chemical element with symbol Fe (from la, ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. In its metallic state, iron is rare in the Earth's crust, limited mainly to deposition by meteorites. Iron ores, by contrast, are among the most abundant in the Earth's crust, although extracting usable metal from them requires kilns or furnaces capable of reaching or higher, about higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BCE and the use of iron tools and weapons began to displace copper alloys, in some regions, only around 1200 BCE. That event is considered the transition from the Bronze Age to the Iron A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chile
Chile, officially the Republic of Chile, is a country in the western part of South America. It is the southernmost country in the world, and the closest to Antarctica, occupying a long and narrow strip of land between the Andes to the east and the Pacific Ocean to the west. Chile covers an area of , with a population of 17.5 million as of 2017. It shares land borders with Peru to the north, Bolivia to the north-east, Argentina to the east, and the Drake Passage in the far south. Chile also controls the Pacific islands of Juan Fernández, Isla Salas y Gómez, Desventuradas, and Easter Island in Oceania. It also claims about of Antarctica under the Chilean Antarctic Territory. The country's capital and largest city is Santiago, and its national language is Spanish. Spain conquered and colonized the region in the mid-16th century, replacing Inca rule, but failing to conquer the independent Mapuche who inhabited what is now south-central Chile. In 1818, after declaring in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Punta Del Cobre Formation
Punta del Cobre Formation ( es, Formación Punta del Cobre) is a geologic formation of Early Cretaceous age cropping out in the interior of Atacama Region, Chile. The formation is of Early Cretaceous age. It is made of massive volcanic rocks, chiefly andesite, dacite, and volcaniclastic rocks representing "flows" and Volcanic breccia of basaltic andesitic and basaltic composition. The rocks of the formation belong to the calc-alkaline magma series. Rocks show intense hydrothermal alteration and hosts significant copper and gold deposits and lesser amounts of zinc and silver. The formation lies in a zone of small-scale mining that supplies the nearby Fundición de Paipote copper smelter. The copper and iron ores of the Dominga prospect are in part emplaced in Punta del Cobre Formation. It was by 1980 considered to be part of Chañarcillo Group but was by 2001 considered to more likely represent the lower member of the underlying In finance, a derivative is a contract that ...

Ore Geology Reviews
Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit.Encyclopædia Britannica. "Ore". Encyclopædia Britannica Online. Retrieved 7 April 2021Neuendorf, K.K.E., Mehl, J.P., Jr., and Jackson, J.A., eds., 2011, Glossary of Geology: American Geological Institute, 799 p. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. 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. Minerals of interest are generally oxides, sulfides, silicates, or native metals such as copper or gold. Ores must be processed to extract the elements of interest from the waste rock. Ore ...

Sebastián Piñera
Miguel Juan Sebastián Piñera Echenique OMCh (; born 1 December 1949) is a Chilean billionaire businessman and politician who served as president of Chile from 2010 to 2014 and again from 2018 to 2022.

Pandora Papers
The Pandora Papers are 11.9 million leaked documents with 2.9 terabytes of data that the International Consortium of Investigative Journalists (ICIJ) published beginning on 3 October 2021. The leak exposed the secret offshore accounts of 35 world leaders, including current and former presidents, prime ministers, and heads of state as well as more than 100 billionaires, celebrities, and business leaders. The news organizations of the ICIJ described the document leak as their most expansive exposé of financial secrecy yet, containing documents, images, emails and spreadsheets from 14 financial service companies, in nations including Panama, Switzerland and the United Arab Emirates, surpassing their previous release of the Panama Papers in 2016, which had 11.5 million confidential documents (2.6 terabytes). At the time of the release of the papers, the ICIJ said it is not identifying its source for the documents. Estimates by the ICIJ of money held offshore (outside the coun ...

Geology Of Coquimbo Region
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes ...
