Antofagasta, Chile
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. Once claimed by Bolivia following the Spanish American wars of independence, Antofagasta was captured by Chile on 14 February 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 Antofagasta, since the mid-19th century copper mining is by far the most important mining activity for Antofagasta, fueling a steady growth in the areas of construction, retail, hotel accommodations, population growth and skyline development until the end of the 2000s com ...

Spanish American Wars Of Independence
The Spanish American wars of independence () took place across the Spanish Empire during the early 19th century. The struggles in both hemispheres began shortly after the outbreak of the Peninsular War, forming part of the broader context of the Napoleonic Wars. The conflict unfolded between the royalists, those who favoured a unitary monarchy, and the patriots, those who promoted either autonomous constitutional monarchies or republics, separated from Spain and from each other. These struggles ultimately led to the independence and secession of continental Spanish America from metropolitan rule, which, beyond this conflict, resulted in a process of Balkanization in Hispanic America. Thus, the strict period of military campaigns ranges from the Battle of Chacaltaya (1809) in present-day Bolivia, to the Battle of Tampico (1829) in Mexico. These conflicts were fought both as irregular warfare and conventional warfare. Some historians claim that the wars began as localized civil war ...

Magallanes And Antártica Chilena Region
The Magallanes Region (), officially the Magallanes y la Antártica Chilena Region () or Magallanes and the Chilean Antarctica Region in English, 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. The region takes its name from the Strait of Magellan which runs through it, which was in turn named after Ferdinand Magellan, the leader of the European expedition that discovered it. 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 ...

Metropolitana De Santiago Region
Santiago Metropolitan Region () 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 seven 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 Metropolitan Region was created. Geography ...

Human Development Index
The Human Development Index (HDI) is a statistical composite index of life expectancy, Education Index, 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 (humanity), human development. A country scores a higher level of HDI when the life expectancy at birth, 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 List of countries by inequality-adjusted Human Development Index, inequality-adjusted Human Development Index (IHDI). While the simple HDI remains useful, it stated that "the IHDI is the actual level of huma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GDP Per Capita
This is a list of countries by nominal GDP per capita. GDP per capita is the total value of a country's finished goods and services (gross domestic product) divided by its total population (per capita). Gross domestic product (GDP) per capita is often considered an indicator of a country's standard of living; however, this is inaccurate because GDP per capita is not a measure of personal income. Measures of personal income include average wage, real income, median income, disposable income and GNI per capita. Comparisons of GDP per capita are also frequently made on the basis of purchasing power parity (PPP), to adjust for differences in the cost of living in different countries, ''see'' List of countries by GDP (PPP) per capita. PPP largely removes the exchange rate problem but not others; it does not reflect the value of economic output in international trade, and it also requires more estimation than GDP per capita. On the whole, PPP per capita figures are more narrowly spre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lithium
Lithium (from , , ) is a chemical element; it has chemical symbol, symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard temperature and pressure, standard conditions, it is the least dense metal and the least dense solid element. Like all alkali metals, lithium is highly reactivity (chemistry), reactive and flammable, and must be stored in vacuum, inert atmosphere, or inert liquid such as purified kerosene or mineral oil. It exhibits a metallic luster (mineralogy), luster. It corrosion, corrodes quickly in air to a dull silvery gray, then black tarnish. It does not occur freely in nature, but occurs mainly as pegmatite, 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 electrolysis, electrolytically from a mixture of lithium chloride and potassium chloride. The Atomic nucleus, nucleus of the lithiu ...

2000s Commodities Boom
The 2000s commodities boom, commodities super cycle or China boom 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 (economics term), 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 due to the 2008 financial crisis and European 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.

Copper Mining In Chile
Chile is the world's largest producer of copper and has been so uninterruptedly since 1983. This activity provides a substantial part of the Chilean state's revenue: slightly less than 6% in 2020, with state-owned copper company Codelco alone generating 2.6% of state revenue. Mining of copper in Chile is done chiefly on giant low-grade porphyry copper deposits which are primarily mined by the following companies; Codelco, BHP, Antofagasta Minerals, Anglo American plc, Anglo American and Glencore. Together these companies stood for 83.6% of the copper output in Chile in 2019 and many copper mining companies are joint ventures involving one at least one of these. Medium-scale mining in Chile, which focuses mainly on copper, produced about 4.5% of the copper mined in the country from 2017 to 2021. Copper is also the main product of small-scale mining in Chile, with about 95% of small-scale miners working in copper mining. One estimate puts the number of active copper mines in Chile ...

Saltpeter
Potassium nitrate is a chemical compound with a sharp, salty, bitter taste and the chemical formula . It is a potassium salt of nitric acid. This salt consists of potassium cations and nitrate anions , and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or ''nitre'' outside the United States). 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 saltpetre (or saltpeter in the United States). Major uses of potassium nitrate are in fertilizers, tree stump removal, rocket propellants and fireworks. It is one of the major constituents of traditional gunpowder (black powder). In processed meats, potassium nitrate reacts with hemoglobin and myoglobin generating a red color. Etymology Nitre, or potassium nitrate, because of its early and global use and production, has many names. As for nitrate, Egyptian and Hebrew words for it had the consonan ...
