San Félix, Venezuela
Ciudad Guayana () (in English Guayana City) is a city in Bolívar State, Venezuela. It stretches 40 kilometers along the south bank of the Orinoco river, at the point where it is joined by its main tributary, the Caroní river. The Caroni crosses the city south-north and divides it on its two main halves: the old town of San Félix in the east, and the new town of Puerto Ordaz () in the west. The city was officially founded in 1961 by the unification of this two former settlements, but the history of San Félix goes back to its foundation in 1724. Within the city limits are located the site of Cachamay Falls and Llovizna Falls.Dydyński, Krzysztof, & Beech, Charlotte (2004). ''Venezuela'', p. 293. Lonely Planet. There are three bridges across the Caroni and the second crossing over the Orinoco, the Orinoquia Bridge, was inaugurated in the city in 2006. With approximately one million people, it is Venezuela's fastest-growing city due to its important iron, steel, aluminium and ...

Orinoquia Bridge
The Second Orinoco crossing or Orinoquia Bridge is a combined road and railway bridge over the Orinoco River near Ciudad Guayana, Venezuela. It was inaugurated on November 13, 2006 and named ''Orinoquia'' Bridge. Prior to its construction, the only crossing of the Orinoco was the Angostura Bridge around 100 km farther upstream at Ciudad Bolívar that was opened in 1967. At the site chosen for the bridge the Orinoco is three kilometres wide with two navigation channels separated by a small island that is revealed during the low water season. The average discharge of the river here varies between 66 000 m³/s and 85 000 m³/s, flowing at up to 2.6 m/s and with a seasonal variation in level of 12.5 m. The crossing is composed of approximately 4.5 km of structures and carries four lanes of road traffic separated into two carriageways by a single railway track in the centre. It consists of two cable stayed navigation spans each of 300 m with a south approach 1320 m long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminium
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity tow ...

Orinoco Mining Company
The Orinoco () is one of the longest rivers in South America at . Its drainage basin, sometimes known as the Orinoquia, covers , with 76.3 percent of it in Venezuela and the remainder in Colombia. It is the fourth largest river in the world by discharge volume of water. The Orinoco River and its tributaries are the major transportation system for eastern and interior Venezuela and the Llanos of Colombia. The environment and wildlife in the Orinoco's basin are extremely diverse. Etymology The river's name is derived from the Warao term for "a place to paddle", itself derived from the terms ''güiri'' (paddle) and ''noko'' (place) i.e. a navigable place. History The mouth of the Orinoco River at the Atlantic Ocean was documented by Christopher Columbus on 1 August 1498, during his third voyage. Its source at the Cerro Delgado–Chalbaud, in the Parima range, was not explored until 453 years later, in 1951. The source, near the Venezuelan–Brazilian border, at ab ...
