El Algarrobo
El Algarrobo is a closed iron mine in north-central Chile. Geologically it is an iron oxide-apatite (IOA) type of deposit. El Algarrobo is part of a wider province of iron ores known as the Chilean Iron Belt. From the 1970s onward El Romeral have come to overshadow El Algarrobo in iron ore production.Millán 1999, p. 155 The establishment of Planta de Pellets in Huasco Huasco () is a Chilean city and commune, in the Huasco Province, Atacama Region.

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. Chile had a population of 17.5 million as of the latest census in 2017 and has a territorial area of , sharing borders with Peru to the north, Bolivia to the northeast, Argentina to the east, and the Drake Passage to the south. The country also controls several Pacific islands, including Juan Fernández Islands, Juan Fernández, Isla Salas y Gómez, Desventuradas Islands, Desventuradas, and Easter Island, and claims about of Antarctica as the Chilean Antarctic Territory. The capital and largest city of Chile is Santiago, and the national language is Spanish language, Spanish. Conquest of Chile, Spain conquered and colonized the region in the mid-16th century, replacing Incas in Central Chile, Inca rule; however, they Arauco War ...

Iron
Iron is a chemical element; it has symbol Fe () 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, forming much of Earth's outer and inner core. It is the fourth most abundant element in the Earth's crust, being mainly deposited by meteorites in its metallic state. Extracting usable metal from iron ores requires kilns or furnaces capable of reaching , about 500 °C (900 °F) higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BC and the use of iron tools and weapons began to displace copper alloys – in some regions, only around 1200 BC. That event is considered the transition from the Bronze Age to the Iron Age. In the modern world, iron alloys, such as steel, stainless steel, cast iron and special steels, are by far the most common industrial metals, due to their mechan ...

Iron Mining
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 (typically greater than about 60% iron) are known as natural ore or irect shipping ore and 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".

Norte Chico, Chile
The ''Norte Chico'' region is one of five natural regions of continental Chile, as defined by the government agency CORFO 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 also subject to droughts ... [...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 belt host also significant resources of cobalt which were deemed by 2017 to have the potential to be extracted as by-products of iron and copper mining along the belt. 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 ...

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 Bethlehem 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 t ...

Planta De Pellets
Planta de Pellets is a mineral processing and pellet-producing plant owned by Compañía Minera del Pacífico (CMP) in Huasco, Atacama Region, Chile. The plant processes iron ore from the mine of Los Colorados in the Chilean Iron Belt. It produces annually 4.5 million metric tons of pellets. The magnetite ore arrives to the plant by train and the leaves it by sea through the adjoining port of Puerto Guacolda II. The plant was launched in 1978 and had then a maximum capacity to produce 3.5 million tons of pellets. For a while it ranked as the second largest pellet plant of its type in the world. In its early years it had over 3000 employees and a substantial part of its workers and engineers were either Japanese or American. Its establishment allowed for the mine of El Algarrobo to remain operational for several years.

Huasco
Huasco () is a Chilean city and commune, in the Huasco Province, Atacama Region. It is the central town of a mining district dominated by medium-scale mining. The port city of Huasco is located 50 km west of Vallenar and close to the town of ''Huasco Bajo'', which lies on the southern bank of the Huasco River and only a few kilometers from its mouth. The coastal route between Huasco Bajo and Carrizal Bajo provides one of the two accesses to Llanos de Challe National Park. The port was used between 1851 and 1873 to ship copper ore, copper regulus, alpaca wool and hides round Cape Horn to Swansea, Glamorgan and Wales. Demographics According to the 2002 census of the National Statistics Institute, Huasco had 7,945 inhabitants (3,999 men and 3,946 women). Of these, 6,445 (81.1%) lived in urban areas and 1,500 (18.9%) in rural areas. The population grew by 5.7% (429 persons) between the 1992 and 2002 censuses.
