El Tofo
El Tofo is an iron ore mine in the Chilean Norte Chico region. The mine lies in northern Coquimbo Region within a larger mining district known as the Chilean Iron Belt. Geologically El Tofo is an iron oxide-apatite deposit. The first record of the iron ores of El Tofo dates to a 1840 study of Ignacy Domeyko. While the mine presents good geological aspects for 19th century mining geographical aspects made access difficult despite being close to the Pacific coast. The mine began to be exploited in 1870 but by 1955 mining diminished as the deposit were close to depletion. Subsequently the El Romeral mine was opened 30 km to the south in replacement. Compañía de Acero del Pacífico obtained the ownership of El Tofo and El Romeral in the early 1970s when it was nationalized during the Presidency of Salvador Allende. Later the ownership passed to Compañía Minera del Pacífico as it was privatized during the Pinochet dictatorship Augusto José Ramón Pinochet Ugarte (, , , ; 2 ...

Iron Ore
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (, 72.4% Fe), hematite (, 69.9% Fe), goethite (, 62.9% Fe), limonite (, 55% Fe) or siderite (, 48.2% Fe). Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. In 2011 the ''Financial Times'' quoted Christopher LaFemina, mining analyst at Barclays Capital, saying that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".

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] |
Norte Chico, Chile
The Norte Chico (''Small North'', ''Near North'', ''Little North'') is one of the five natural regions into which CORFO divided continental Chile in 1950. Its northern border is formed by the limit with the Far North, to the west lies the Pacific Ocean, to the east the Andes mountains and Argentina, and to the south the Zona Central natural region. Although from a strictly geographic point of view, this natural region corresponds to the Chilean territory between the rivers Copiapó and Aconcagua, traditionally the Norte Chico refers to the zone comprising the regions of Atacama and Coquimbo. This region was home to the Diaguita people. Geography The near north (Norte Chico) extends from the southern border of the Atacama Desert to about 32° south latitude, or just north of Santiago. It is a semiarid region whose central area receives an average of about 25 mm of rain during each of the four winter months, with trace amounts the rest of the year. The near north is a ...

Coquimbo Region
The Coquimbo Region ( es, Región de Coquimbo, ) is one of Chile's 16 regions (first order administrative divisions). It is bordered by Atacama to the north, Valparaíso to the south, Argentina to the east, and the Pacific Ocean to the west. It is approximately north of the national capital, Santiago. The capital and largest city is La Serena. Other important cities include the seaport Coquimbo and the agricultural centre Ovalle. Geography and ecology The Coquimbo Region forms the narrowest part, or 'waist' of Chile, and is hence one of the country's more mountainous regions, as the Andes range runs closer to the sea than elsewhere. The region has notable marine species as well as taxa that are associated with the mountainous regions. With respect to marine organisms, the upwelling areas encourage bioproductivity off of this Pacific Coast area of Chile. In the southern mountainous areas of the Coquimbo Region, the rare and endangered Chilean Wine Palm is found, whose ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chilean Iron Belt
The Chilean Iron Belt is a geological province rich in iron ore deposits in northern Chile. It extends as a north-south beld along the western part of the Chilean regions of Coquimbo and Atacama, chiefly between the cities of La Serena and Taltal. The belt follows much of the Atacama Fault System and is about 600 km long and 25 km broad. Iron oxide-apatite, iron oxide copper gold ore deposits (IOCG) and manto-type copper and silver are the main types of deposits. Iron-apatite and IOCG are considered to have different origins. Manto-type deposits are concentrated in the northern part of the belt and are chiefly emplaced on rocks of La Negra Formation. The ores of the Chilean Iron Belt formed in separate pulses in the Cretaceous period as result of magmatic and hydrothermal processes. At least part of the iron oxide-apatite rock originated from molten iron in the form of lava, tephra. and intrusions. Thus iron oxide apatite magma cooled into rock variously from surface volcano ...

Iron Oxide-apatite
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 Age. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ignacy Domeyko
Ignacy Domeyko or Domejko, pseudonym: ''Żegota'' ( es, Ignacio Domeyko, ; 31 July 1802 – 23 January 1889) was a Polish geologist, mineralogist, educator, and founder of the University of Santiago, in Chile. Domeyko spent most of his life, and died, in his adopted country, Chile. After a youth passed in partitioned Poland, Domeyko participated in the Polish–Russian War 1830–31. Upon Russian victory, he was exiled, spending part of his life in France (where he had gone with a fellow Philomath, Polish poet Adam Mickiewicz) before eventually settling in Chile, whose citizen he became. He lived some 50 years in Chile and made major contributions to the study of that country's geography, geology and mineralogy. His observations on the circumstances of poverty-stricken miners and of their wealthy exploiters had a profound influence on those who would go on to shape Chile's labor movement. Domeyko is seen as having had close ties to several countries and thus in 2002, when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
El Romeral Mine
El Romeral is an iron mine in north-central Chile. The mine benefits from being located only 22 km NNE of the city of La Serena and being next to Guayacán, a port with conditions for high-tonnage cargo ships.Millán 1999, p. 153 The mine emerged as a replacement for the nearby mine of El Tofo that was close to depletion in the early 1950s. El Romeral was Bethehem Chile Iron Mines last major investment as Compañía de Acero del Pacífico obtained the ownership of El Tofo and El Romeral in the early 1971 when they were nationalized during the Presidency of Salvador Allende. Despite being initially an expensive mine in terms of infrastructure investment and having a troublesome geology El Romeral proved with time to host more iron than initially thought. Following an ownership restructuring Compañía Minera del Pacífico, now holds control of the mine. During the 1970s El Romeral would produce enough iron to fully supply the steel mill of Huachipato.Millán 1999, p. 154 From ...

Compañía De Acero Del Pacífico
The Compañía de Acero del Pacífico, also known by its acronym CAP, is the main iron and steel industry of Chile with its main facilities at Huachipato, Chile, Huachipato near the port of Talcahuano in Bío Bío Region. As result of Presidency of Salvador Allende, Allende's nationalization of the mining industry in the early 1970s Compañía de Acero del Pacífico obtained ownership of the iron mine of El Tofo and El Romeral mine, El Romeral.

Nationalization
Nationalization (nationalisation in British English) is the process of transforming privately-owned assets into public assets by bringing them under the public ownership of a national government or state. Nationalization usually refers to private assets or to assets owned by lower levels of government (such as municipalities) being transferred to the state. Nationalization contrasts with privatization and with demutualization. When previously nationalized assets are privatized and subsequently returned to public ownership at a later stage, they are said to have undergone renationalization. Industries often subject to nationalization include the commanding heights of the economy – telecommunications, electric power, fossil fuels, railways, airlines, iron ore, media, postal services, banks, and water – though, in many jurisdictions, many such entities have no history of private ownership. Nationalization may occur with or without financial compensation to the former owners. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Presidency Of Salvador Allende
Salvador Allende was the president of Chile from 1970 until his 1973 suicide, and head of the Popular Unity government; he was a Socialist and Marxist elected to the national presidency of a liberal democracy in Latin America.Don MabryAllende's Rise and Fall''. In August 1973 the Chilean Senate declared the Allende administration to be "unlawful," Allende's presidency was ended by a military coup before the end of his term. During Allende's three years, Chile gradually transitioned into a socialist state. During his tenure, Chilean politics reached a state of civil unrest amid, political polarization, hyperinflation, lockouts, economic sanctions, CIA-sponsored interventionism and a failed coup in June 1973. Allende's coalition, Unidad Popular, faced the problem of being a minority in the congress and it was plagued by factionalism. On 11 September 1973, a successful coup led by General Augusto Pinochet overthrew the government of Allende. During the bombing of the presid ...
