Los Leones Dam
The Los Leones Dam is a tailings dam on Los Leones River, a tributary of Blanco River, about northeast of Santiago, in Los Andes Province, Chile. The dam was constructed in segments between 1980 and 1999 and is now used only for emergencies. The dam is tall on its upstream face and tall on its downstream face; the height at its axis is . It is one of the tallest tailings dams in the world.

Santiago
Santiago (, ; ), also known as Santiago de Chile, is the capital and largest city of Chile as well as one of the largest cities in the Americas. It is the center of Chile's most densely populated region, the Santiago Metropolitan Region, whose total population is 8 million which is nearly 40% of the country's population, of which more than 6 million live in the city's continuous urban area. The city is entirely in the country's central valley. Most of the city lies between above mean sea level. Founded in 1541 by the Spanish conquistador Pedro de Valdivia, Santiago has been the capital city of Chile since colonial times. The city has a downtown core of 19th-century neoclassical architecture and winding side-streets, dotted by art deco, neo-gothic, and other styles. Santiago's cityscape is shaped by several stand-alone hills and the fast-flowing Mapocho River, lined by parks such as Parque Forestal and Balmaceda Park. The Andes Mountains can be seen from most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tailings Dam
A tailings dam is typically an earth-fill embankment dam used to store byproducts of mining operations after separating the ore from the gangue. Tailings can be liquid, solid, or a slurry of fine particles, and are usually highly toxic and potentially radioactive. Solid tailings are often used as part of the structure itself. Tailings dams rank among the largest engineered structures on earth. The Syncrude Mildred Lake Tailings Dyke in Alberta, Canada, is an embankment dam about long and from high. It is the largest dam structure on earth by volume, and as of 2001 it was believed to be the largest earth structure in the world by volume of fill. There are key differences between tailings dams and the more familiar hydroelectric dams. Tailings dams are designed for permanent containment, meaning they are intended to "remain there forever". Copper, gold, uranium and other mining operations produce varied kinds of waste, much of it toxic, which pose varied challenges for long-te ...

Los Andes Province, Chile
Los Andes Province ( es, Provincia de Los Andes) is one of eight provinces of the central Chilean region of Valparaíso (V). The city of Los Andes is the capital of the province. Administration As a province, Los Andes is a second-level administrative division, governed by a provincial delegate who is appointed by the president. Edith Quiroz Ortiz, appointed by president Piñera on April 22, 2010, was the first woman to hold the office of Governor of Los Andes. The presidential provincial delegate appointed by president Gabriel Boric is Cristian Aravena Reyes, a Socialist. Communes The province is composed of four communes ( Spanish: ''comunas''), each governed by a municipality consisting of an alcalde and municipal council: *Calle Larga Calle Larga ("long road" in Spanish) is city and one of four communes in the Los Andes Province of central Chile's Valparaíso Region.

Dams In Chile
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam.

Mining In Chile
The mining sector in Chile is one of the pillars of Chilean economy and copper exports alone stands for more than one third of government income. Most mining in Chile is concentrated to the Norte Grande region spanning most of the Atacama Desert. Mining products of Chile includes copper, gold, silver, molybdenum, iron and coal. Chile was, in 2019, the world's largest producer of copper, iodine and rhenium, the second largest producer of lithium and molybdenum, the sixth largest producer of silver, the seventh largest producer of salt, the eighth largest producer of potash, the thirteenth producer of sulfur and the thirteenth producer of iron ore in the world. In the production of gold, between 2006 and 2017, the country produced annual quantities ranging from 35.9 tons in 2017 to 51.3 tons in 2013. Nitrate Mining nitrate in the North of Chile defined the country's history from the late 19th century to the mid 20th. Indeed the period 1873-1914 is referred to as the Saltpetre Repu ...

Buildings And Structures In Valparaíso Region
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tailings Dams
In mining, tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are different to overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to concentrate the valuable minerals, or hard rock mining, which pulverizes the rock containing the ore and then relies on chemical reactions to concentrate the sought-after material. In the latter, the extraction of minerals from ore requires comminution, i.e., grinding the ore into fine particles to facilitate extraction of the target element(s). Because of this comminution, tailings consist of a slurry of fine particles, ranging from the size of a grain of sand to a few micrometres. Mine tailings are usually produced from the mill in slurry form, which is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
