Corocoro United Copper Mines
The Corocoro United Copper Mines, Ltd. was the largest copper mine in Bolivia, an honor previously held by Compania Corocoro de Bolivia. The corporate office was at 151 Finsbury Pavement House, London, England, while the mine office was at Coro Coro, Bolivia. It was organized August 6, 1909 under the laws of Great Britain. The lands included 515 claims in the Coro Coro district. The principal mines were the Wisk'achani, formerly owned by J. K. Child & Co., Ltd.; the Santa Rosa, formerly owned by Carreras Hermanos; and the Guallatiri, formerly owned by the Succession Noel Berthin. The mines were opened on two successive conglomerate strata of different geological horizons, and similar only in their origin and cupriferous nature. The mines are believed to have been worked by the Incas. The nearest water supply was the Rio Desaguadero, away, down which the copper was shipped by way of Puerto de Desaguadero, and from there to Mollendo, Chile Chile, officially the Republi ...

Corocoro United Copper Mines Ltd 1912
is a Japanese monthly manga magazine published by Shogakukan, established on May 15, 1977. Its main target is elementary school-aged boys, younger than the readers of shōnen manga. Several of its properties, like ''Doraemon'' and the ''Pokémon'' series of games, have gone on to be cultural phenomena in Japan. The name comes from a phenomime which means "rolling" and also represents something spherical, fat, or small, because children supposedly like such things. The magazine is A5-sized, about 6 cm ( in) thick, and each issue is 750 pages long. ''CoroCoro Comic'' is released monthly with new issues on the 15th of each month (or earlier if the 15th falls on a weekend). ''CoroCoro Comic'' sold 400million copies as of April 2017, making it one of the best-selling comic/manga magazines. The magazine has three sisters: ''Bessatsu CoroCoro Comic'' (別冊コロコロコミック), ''CoroCoro Ichiban!'' (コロコロイチバン) and ''CoroCoro Aniki'' (コロコロアニ ...

Copper Extraction Techniques
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 Inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

London
London is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Romans as '' Londinium'' and retains its medieval boundaries.See also: Independent city § National capitals The City of Westminster, to the west of the City of London, has for centuries hosted the national government and parliament. Since the 19th century, the name "London" has also referred to the metropolis around this core, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which largely comprises Greater London, governed by the Greater London Authority.The Greater London Authority consists of the Mayor of London and the London Assembly.

Coro Coro, Bolivia
Coro Coro (Aymara: ''Kuru Kuru'') is a small town in the La Paz Department in Bolivia. It is the seat of the Coro Coro Municipality, the first municipal section of the Pacajes Province, and it is the seat of the province. Coro Coro, also known as Corocoro, was one of the most important mining areas in Bolivia because of its copper deposits and was home to the Corocoro United Copper Mines. That changed after 1985 when due to various economic and political reasons the mining center was closed and its workers left the area. Since then, the development of the town has been stagnant. Coro Coro contains in its territory several natural heritage landmarks, such as Kuntur Jipiña, the salt lake of Jayuma Llallawa and the church of Qaqinkura ''(Caquingora)''.

Conglomerate (geology)
Conglomerate () is a clastic sedimentary rock that is composed of a substantial fraction of rounded to subangular gravel-size clasts. A conglomerate typically contains a matrix of finer-grained sediments, such as sand, silt, or clay, which fills the interstices between the clasts. The clasts and matrix are typically cemented by calcium carbonate, iron oxide, silica, or hardened clay. Conglomerates form by the consolidation and lithification of gravel. They can be found in sedimentary rock sequences of all ages but probably make up less than 1 percent by weight of all sedimentary rocks. In terms of origin and depositional mechanisms, they are closely related to sandstones and exhibit many of the same types of sedimentary structures, e.g., tabular and trough cross-bedding and graded bedding.Boggs, S. (2006) ''Principles of Sedimentology and Stratigraphy.'', 2nd ed. Prentice Hall, New York. 662 pp. Friedman, G.M. (2003) ''Classification of sediments and sedimentary rocks.'' In G ...

Strata
In geology and related fields, a stratum ( : strata) is a layer of rock or sediment characterized by certain lithologic properties or attributes that distinguish it from adjacent layers from which it is separated by visible surfaces known as either '' bedding surfaces'' or ''bedding planes''.Salvador, A. ed., 1994. ''International stratigraphic guide: a guide to stratigraphic classification, terminology, and procedure. 2nd ed.'' Boulder, Colorado, The Geological Society of America, Inc., 215 pp. . Prior to the publication of the International Stratigraphic Guide, older publications have defined a stratum as either being either equivalent to a single bed or composed of a number of beds; as a layer greater than 1 cm in thickness and constituting a part of a bed; or a general term that includes both ''bed'' and ''lamina''.Neuendorf, K.K.E., Mehl, Jr., J.P., and Jackson, J.A. , eds., 2005.

Inca Empire
The Inca Empire (also known as the Incan Empire and the Inka Empire), called ''Tawantinsuyu'' by its subjects, (Quechua for the "Realm of the Four Parts", "four parts together" ) was the largest empire in pre-Columbian America. The administrative, political and military center of the empire was in the city of Cusco. The Inca civilization arose from the Peruvian highlands sometime in the early 13th century. The Spanish began the conquest of the Inca Empire in 1532 and by 1572, the last Inca state was fully conquered. From 1438 to 1533, the Incas incorporated a large portion of western South America, centered on the Andean Mountains, using conquest and peaceful assimilation, among other methods. At its largest, the empire joined modern-day Peru, what are now western Ecuador, western and south central Bolivia, northwest Argentina, the southwesternmost tip of Colombia and a large portion of modern-day Chile, and into a state comparable to the historical empires of Eurasia ...

Desaguadero River (Bolivia And Peru)
The Desaguadero River, also known as Risawariru or Uchusumain, is a river shared between Bolivia and Peru. It drains Lake Titicaca from the southern part of the river basin, flowing south and draining approximately five percent of the lake's flood waters into Lake Uru Uru and Lake Poopó. Its source in the north is very near the Peruvian border. It is navigable only by small craft and supports indigenous communities such as the Uru Muratu community.
