El Algarrobo
El Algarrobo is an 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 El Romeral is a municipality located in the province of Toledo, Castile-La Mancha, Spain.

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] |
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] |
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 (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".

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 ...

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 ...

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 ...
