Antamina Tailings Dam
The Antamina Tailings Dam, also known as the Antamina Tailings Impoundment Facility, is a tailings dam located in the Huincush Ravine east of Huaraz in the Ancash Region of Peru. The purpose of the dam is to store tailings processed at the nearby Antamina mine. In 2003, Golder Associates, Burnaby, B.C. was awarded the 2002 Canadian Consulting Engineering Award for its innovative design of the dam. Background The dam was designed by Golder Associates, Burnaby, B.C. and Ingetec SA between 1998 and 1999. Construction on the high concrete-face rock-fill starter dam began in 2000 was complete in April 2001. A reservoir was filled behind the dam assist the concentrater. By April 2003, the dam was raised from its original elevation of above sea level to . The dam will continually be raised until it reaches tall at an elevation of and length of . Currently the dam is undergoing its fourth raising to in height. Design and operation As a base for the dam, a concrete-face rock-fill ...

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-term ...

Ancash Region
Ancash ( qu, Anqash; es, Áncash ) is a department and region in northern Peru. It is bordered by the departments of La Libertad on the north, Huánuco and Pasco on the east, Lima on the south, and the Pacific Ocean on the west. Its capital is the city of Huaraz, and its largest city and port is Chimbote. The name of the region originates from the Quechua word ('light, of little weight'), from ('blue') or from ('eagle'). Geography Ancash is a land of contrasts: it features two great longitudinal valleys, which combine the mountain characteristics of the Callejón de Huaylas (Alley of Huaylas) with the sylvan ones of the Alto Marañón. Kilometres of sandy beaches and the blue waters of the Pacific. The territory of the coast, high plateaux and Andean '' punas'' of the department are flat, while the rest of the territory, in the Andes, is very rough. In the west, there are slopes with strong declivity form narrow canyons with abrupt and deserted sides. The rough territor ...

Antamina Mine
The Antamina mine in the Andes Mountains of Peru is one of the largest copper/zinc mines in the world. It is an open pit mine owned by Teck Resources which had an estimated life of mine at 15 years. It also produced molybdenum. It produced 390,800 tons of copper concentrate in 2006, 461,000 tons in 2013. The total capital expenditure of the mine by 2013 was US$2.3 billion. İt is located at an altitude of 4,300 meters above sea level. The mine is expected to have its stockpiles depleted by 2022 and is thus scheduled to cease production by 2019. Klohn Crippen Berger (KCB) is in charge of the preparation for the Closure Plan. See also *Antamina Tailings Dam *Zinc mining *List of mines in Peru *Copper mining 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, loca ... References External l ...

Ore Concentrate
Ore concentrate, dressed ore or simply concentrate is the product generally produced by metal ore mines. The raw ore is usually ground finely in various comminution operations and gangue (waste) is removed, thus concentrating the metal component. The concentrate is then transported to various physical or chemical processes called hydrometallurgy, pyrometallurgy smelters, and electrometallurgy where it is used to produce useful metals. Ore concentrates are classified as a hazardous cargo for shipping by the International Maritime Solid Bulk Cargoes (IMSBC) Code, which is part of the SOLAS Convention, due to their tendency under certain conditions, to liquefy, which may affect the stability of the ship due to the free surface effect potentially causing a ship to capsize Capsizing or keeling over occurs when a boat or ship is rolled on its side or further by wave action, instability or wind force beyond the angle of positive static stability or it is upside down in the water.

Geomembranes
A geomembrane is very low permeability synthetic membrane liner or barrier used with any geotechnical engineering related material so as to control fluid (liquid or gas) migration in a human-made project, structure, or system. Geomembranes are made from relatively thin continuous polymeric sheets, but they can also be made from the impregnation of geotextiles with asphalt, elastomer or polymer sprays, or as multilayered bitumen geocomposites. Continuous polymer sheet geomembranes are, by far, the most common. Manufacturing The manufacturing of geomembranes begins with the production of the raw materials, which include the polymer resin, and various additives such as antioxidants, plasticizers, fillers, carbon black, and lubricants (as a processing aid). These raw materials (i.e., the "formulation") are then processed into sheets of various widths and thickness by extrusion, calendering, and/or spread coating. Geomembranes dominate the sales of geosynthetic products, at US$1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dams In Peru
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, tap water, human consumption, Industrial water, 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 Dike (construction), dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam (Jordan), 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.

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] |
