Pedro Gamboni
Pedro Gamboni (September 26, 1825 - December 27, 1895) was a Chilean chemical engineer who did important studies related to saltpeter and iodine in the regions of Tarapaca and Antofagasta.Gamboni invented a new method to extract nitrate from caliche leading to the phasing out of the older firewood and labour intensive paradas method The paradas method ( es, método de paradas, ''sistema de paradas'') was a process to extract nitrate from caliche by leaching. In this method caliche was boiled in water in large pans called "paradas". It was a firewood and labour-intensive proces ... in the 1850s.

Pedro Gamboni Vera 2
Pedro is a masculine given name. Pedro is the Spanish, Portuguese, and Galician name for ''Peter''. Its French equivalent is Pierre while its English and Germanic form is Peter. The counterpart patronymic surname of the name Pedro, meaning "son of Peter" (compare with the English surname Peterson) is Pérez in Spanish, and Peres in Galician and Portuguese, Pires also in Portuguese, and Peiris in coastal area of Sri Lanka (where it originated from the Portuguese version), with all ultimately meaning "son of Pêro". The name Pedro is derived via the Latin word "petra", from the Greek word "η πέτρα" meaning "stone, rock". The name Peter itself is a translation of the Aramaic ''Kephas'' or '' Cephas'' meaning "stone". An alternate archaic spelling is ''Pêro''. Pedro may refer to: Notable people Monarchs, mononymously *Pedro I of Portugal *Pedro II of Portugal *Pedro III of Portugal *Pedro IV of Portugal, also Pedro I of Brazil *Pedro V of Portugal *Pedro II of Brazi ...

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] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tarapacá Region
The Tarapacá Region ( es, Región de Tarapacá, ) is one of Chile's 16 first-order administrative divisions. It comprises two provinces, Iquique and Tamarugal. It borders the Chilean Arica and Parinacota Region to the north, Bolivia's Oruro Department and Potosí Department on the east, Chile's Antofagasta Region to the south and the Pacific Ocean to the west. The port city of Iquique is the region's capital. Much of the region was once the Tarapacá Province of Peru, which was annexed by Chile under the 1883 Treaty of Ancón at the close of the War of the Pacific. The region was important economically as a site of intense saltpeter mining, before synthetic nitrate manufacturing became possible. A number of abandoned mining towns can still be found in the region. The present day Tarapacá Region was created in 2007 by subdividing the former Tarapacá Region under Law No. 20,175, which was signed by President Michelle Bachelet in Arica.

Antofagasta
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nitratine
Nitratine or nitratite, also known as cubic niter (UK: nitre), soda niter or Chile saltpeter (UK: Chile saltpetre), is a mineral, the naturally occurring form of sodium nitrate, NaNO3. Chemically it is the sodium analogue of saltpeter. Nitratine crystallizes in the trigonal system, but rarely occurs as well formed crystals. It is isostructural with calcite. It is quite soft and light with a Mohs hardness of 1.5 to 2 and a specific gravity of 2.24 to 2.29. Its refractive indices are nω=1.587 and nε=1.336. The typical form is as coatings of white, grey to yellowish brown masses. The rare crystals when found typically have the scalenohedral form of the calcite structure. It is found only as an efflorescence in very dry environments. It is very soluble in water such that it is deliquescent and will absorb water out of the air and turn into a ''puddle'' of sodium nitrate solution when exposed to humid air. Nitratine was once an important source of nitrates for fertilizer and other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caliche
Caliche () is a sedimentary rock, a hardened natural cement of calcium carbonate that binds other materials—such as gravel, sand, clay, and silt. It occurs worldwide, in aridisol and mollisol soil orders—generally in arid or semiarid regions, including in central and western Australia, in the Kalahari Desert, in the High Plains of the western United States, in the Sonoran Desert, Chihuahuan Desert and Mojave Desert of North America, and in eastern Saudi Arabia at Al-Hasa. Caliche is also known as calcrete or kankar (in India). It belongs to the duricrusts. The term ''caliche'' is Spanish and is originally from the Latin ''calx'', meaning lime. Caliche is generally light-colored, but can range from white to light pink to reddish-brown, depending on the impurities present. It generally occurs on or near the surface, but can be found in deeper subsoil deposits, as well. Layers vary from a few inches to feet thick, and multiple layers can exist in a single location.

Paradas Method
The paradas method ( es, método de paradas, ''sistema de paradas'') was a process to extract nitrate from caliche by leaching. In this method caliche was boiled in water in large pans called "paradas". It was a firewood and labour-intensive process. The paradas method was phased out in the 1850s by a new system invented by Pedro Gamboni which required less fuel and labour. The paradas method led to a massive deforestation of Pampa del Tamarugal around La Tirana La Tirana is a Chilean town in the commune of Pozo Almonte in El Tamarugal Province, Tarapacá Region. The town lies in an oasis in the middle of the Pampa del Tamarugal, about 72 km inland from the port of Iquique. The town is notable for i ... and Canchones and some areas to the south of these localities.
