Antofagasta Minerals
Antofagasta () is a port city in northern Chile, about north of Santiago. It is the capital of Antofagasta Province and Antofagasta Region. According to the 2015 census, the city has a population of 402,669. After the Spanish American wars of independence, Bolivia claimed Antofagasta as part of its territory. Despite having an overwhelmingly ethnic Chilean population, Chile recognised Bolivian sovereignty of Antofagasta in 1866, but in 1879 Chile recanted its recognition of Bolivian sovereignty citing a Bolivian breach of the latest boundary treaty. Antofagasta was captured by Chile in February 14 1879 triggering the War of the Pacific (1879–83). Chilean sovereignty was officially recognised by Bolivia under the terms of the 1904 Treaty of Peace and Friendship. The city of Antofagasta is closely linked to mining activity, being a port and the chief service hub for one of Chile's major mining areas. While silver and saltpeter mining have been historically important for A ...

Boundary Treaty Of 1874 Between Chile And Bolivia
The Boundary Treaty of 1874 between Chile and Bolivia, also called the Treaty of Sucre, was signed in Sucre on August 6, 1874 by the Bolivian Minister of Foreign Affairs Mariano Baptista and the Chilean plenipotentiary minister Carlos Walker Martínez. It superseded the Boundary Treaty of 1866 between Chile and Bolivia and it kept the border between both countries at the 24° South parallel from the Pacific Ocean to the eastern border of Chile. The Treaty abolished the zone of bipartite tax collection on the export dues on minerals found between parallel 23°S and 25°S, and Bolivia promised explicitly in article 4 of the Treaty not to augment the existing taxes for twenty-five years on Chilean capital and industry. To realize its Saltpeter Monopoly, Peru tried fruitless to prevent the signing of the treaty. In February 1878, Bolivia imposed a new tax upon saltpeter and one year later began the War of the Pacific. The Treaty of 1874 is of capital importance in the understandin ...

Magallanes And Antártica Chilena Region
The Magallanes Region (), officially the Magallanes y la Antártica Chilena Region ( es, Región de Magallanes y de la Antártica Chilena), is one of Chile's 16 first order administrative divisions. It is the southernmost, largest, and second least populated region of Chile. It comprises four provinces: Última Esperanza, Magallanes, Tierra del Fuego, and Antártica Chilena. Magallanes's geographical features include Torres del Paine, Cape Horn, Tierra del Fuego island, and the Strait of Magellan. It also includes the Antarctic territory claimed by Chile. Despite its large area, much of the land in the region is rugged or closed off for sheep farming, and is unsuitable for settlement. 80% of the population lives in the capital Punta Arenas, a major market city and one of the main hubs for Antarctic exploration. The main economic activities are sheep farming, oil extraction, and tourism. It is also the region with the lowest poverty level in Chile (5.8%); households in Magall ...

Metropolitana De Santiago Region
Santiago Metropolitan Region ( es, link=no, Región Metropolitana de Santiago) is one of Chile's 16 first-order administrative divisions. It is the country's only landlocked administrative region and contains the nation's capital, Santiago. Most commercial and administrative centers are located in the region, including Chile's main international airport, Arturo Merino Benítez International Airport. With an area of and population over 7 million, it is Chile's most populated and most densely populated region. History The region's history of European influence started in 1542, a few days after Santiago was founded. When the Santiago cabildo was built, its function was to supervise the entire territory. Later, with the creation of the cities of La Serena and Concepción and the creation of their respective cabildos, its territorial reach was reduced. On 30 August 1826, 8 provinces were created, with the Santiago Province being one of them, but it wasn't until 1980 that the ...

Human Development Index
The Human Development Index (HDI) is a statistic composite index of life expectancy, education (mean years of schooling completed and expected years of schooling upon entering the education system), and per capita income indicators, which is used to rank countries into four tiers of human development. A country scores a higher level of HDI when the lifespan is higher, the education level is higher, and the gross national income GNI (PPP) per capita is higher. It was developed by Pakistani economist Mahbub ul Haq and was further used to measure a country's development by the United Nations Development Programme (UNDP)'s Human Development Report Office. The 2010 Human Development Report introduced an Inequality-adjusted Human Development Index (IHDI). While the simple HDI remains useful, it stated that "the IHDI is the actual level of human development (accounting for inequality), while the HDI can be viewed as an index of 'potential' human development (or the maximum l ...

Digital Object Identifier
A digital object identifier (DOI) is a persistent identifier or handle used to uniquely identify various objects, standardized by the International Organization for Standardization (ISO). DOIs are an implementation of the Handle System; they also fit within the URI system ( Uniform Resource Identifier). They are widely used to identify academic, professional, and government information, such as journal articles, research reports, data sets, and official publications. DOIs have also been used to identify other types of information resources, such as commercial videos. A DOI aims to resolve to its target, the information object to which the DOI refers. This is achieved by binding the DOI to metadata about the object, such as a URL where the object is located. Thus, by being actionable and interoperable, a DOI differs from ISBNs or ISRCs which are identifiers only. The DOI system uses the indecs Content Model for representing metadata. The DOI for a document remains fixed over t ...

Lithium
Lithium (from el, λίθος, lithos, lit=stone) is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the least dense metal and the least dense solid element. Like all alkali metals, lithium is highly reactive and flammable, and must be stored in vacuum, inert atmosphere, or inert liquid such as purified kerosene or mineral oil. When cut, it exhibits a metallic luster, but moist air corrodes it quickly to a dull silvery gray, then black tarnish. It never occurs freely in nature, but only in (usually ionic) compounds, such as pegmatitic minerals, which were once the main source of lithium. Due to its solubility as an ion, it is present in ocean water and is commonly obtained from brines. Lithium metal is isolated electrolytically from a mixture of lithium chloride and potassium chloride. The nucleus of the lithium atom verges on instability, since the two stable lithium isotopes foun ...

2000s Commodities Boom
The 2000s commodities boom or the commodities super cycle was the rise of many physical commodity prices (such as those of food, oil, metals, chemicals and fuels) during the early 21st century (2000–2014), following the Great Commodities Depression of the 1980s and 1990s. The boom was largely due to the rising demand from emerging markets such as the BRIC countries, particularly China during the period from 1992 to 2013, as well as the result of concerns over long-term supply availability. There was a sharp down-turn in prices during 2008 and early 2009 as a result of the credit crunch and 2010 European sovereign debt crisis, sovereign debt crisis, but prices began to rise as demand recovered from late 2009 to mid-2010. Oil began to slip downwards after mid-2010, but peaked at $101.80 on 30 and 31 January 2011, as the Egyptian revolution of 2011 broke out, leading to concerns over both the safe use of the Suez Canal and overall security in Arabia itself. On 3 March, Libya's Natio ...

Copper Mining
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals. It is then concentrated using mineral flotation. The concentrate is typically sold to distant smelters, although some large mines have smelters located nearby. Such colocation of mines and smelters was more typical in the 19th and early 20th centuries, when smaller smelters could be economic. The sulfide concentrates are typically smelted in such furnaces as the Outokumpu or Inco f ...

Saltpeter
Potassium nitrate is a chemical compound with the chemical formula . This alkali metal nitrate salt is also known as Indian saltpetre (large deposits of which were historically mined in India). It is an ionic salt of potassium ions K+ and nitrate ions NO3−, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or ''nitre'' in the UK). It is a source of nitrogen, and nitrogen was named after niter. Potassium nitrate is one of several nitrogen-containing compounds collectively referred to as saltpeter (or ''saltpetre'' in the UK). Major uses of potassium nitrate are in fertilizers, tree stump removal, rocket propellants and fireworks. It is one of the major constituents of gunpowder (black powder). In processed meats, potassium nitrate reacts with hemoglobin and myoglobin generating a red color. Etymology Potassium nitrate, because of its early and global use and production, has many names. Hebrew and Egyptian words for it had the consonants n-t-r ...
