La Colosa Mine
La Colosa is a porphyry Gold mining, gold mine in Colombia. The mine is located in Cajamarca, Tolima, Cajamarca, Tolima Department, Tolima on the eastern flanks of the Cordillera Central (Colombia), Central Ranges of the Colombian Andes. La Colosa has estimated inferred resources of of gold, grading at of Au. In 2015, the mine produced of gold.Gold - UPME In 2016, 88.4% of the mining value in Colombia came from coal and gold combined, with nickel following at 9.3%. Description La Colosa, covering an area of , is the second major greenfield discovery in Colombia, after Gramalote mine, Gramalote and believed to have a potential of producing between of gold per year for 20 years. La Colosa gold project, started in 2006, is based on low- ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cajamarca, Tolima
Cajamarca is a town and municipality in the Tolima Department of Colombia. The population of the municipality was 17,309 as of the 2018 census. The municipality has two populated centres, the town centre of Cajamarca and the locality of Anaime. It is located along the Pan-American Highway. In 1886, colonisers from Antioquia colonised the area currently known as Anaime, and started to develop the land for agriculture. In 1913, the Bishop of Ibagué Ismael Perdomo bought the land of the municipality and officially founded the municipality of Cajamarca, which stands for 'cold land' in Quechua. The main economic activity is agriculture, and the town is also known as the 'agricultural larder' of Colombia.El Tiempo. 1997. "Cajamarca despensa agrícola del Tolima." ''El Tiempo'', 21 May. https://www.eltiempo.com/archivo/documento/MAM-600830 Internationally, the town is best known as the location of the La Colosa gold mining project of AngloGold Ashanti AngloGold Ashanti Lim ...

Silicate
In chemistry, a silicate is any member of a family of polyatomic anions consisting of silicon and oxygen, usually with the general formula , where . The family includes orthosilicate (), metasilicate (), and pyrosilicate (, ). The name is also used for any salt of such anions, such as sodium metasilicate; or any ester containing the corresponding chemical group, such as tetramethyl orthosilicate. The name "silicate" is sometimes extended to any anions containing silicon, even if they do not fit the general formula or contain other atoms besides oxygen; such as hexafluorosilicate .Most commonly, silicates are encountered as silicate minerals. For diverse manufacturing, technological, and artistic needs, silicates are versatile materials, both natural (such as granite, gravel, and garnet) and artificial (such as Portland cement, ceramics, glass, and waterglass). Structural principles In all silicates, silicon atom occupies the center of an idealized tetrahedron whose corner ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface Mines In Colombia
A surface, as the term is most generally used, is the outermost or uppermost layer of a physical object or space. It is the portion or region of the object that can first be perceived by an observer using the senses of Visual perception, sight and Somatosensory system, touch, and is the portion with which other materials first interact. The surface of an object is more than "a mere geometric solid", but is "filled with, spread over by, or suffused with perceivable qualities such as color and warmth". The concept of surface has been abstracted and formalized in mathematics, specifically in geometry. Depending on the properties on which the emphasis is given, there are several non equivalent such formalizations, that are all called ''surface'', sometimes with some qualifier, such as algebraic surface, smooth surface or fractal surface. The concept of surface and its mathematical abstraction are both widely used in physics, engineering, computer graphics, and many other discipline ...
