Antamina
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 This is a list of mines in Peru.

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 ...

Zinc Mining
Zinc mining is the process by which mineral forms of the metal zinc are extracted from the earth through mining. A zinc mine is a mine that produces zinc minerals in ore as its primary product. Common co-products in zinc ores include minerals of lead and silver. Other mines may produce zinc minerals as a by-product of the production of ores containing more valuable minerals or metals, such as gold, silver or copper. Mined ore is processed, usually on site, to produce one or more metal-rich concentrates, then transported to a zinc smelter for production of zinc metal. Global zinc mine production in 2020 was estimated to be 12 million tonnes. The largest producers were China (35%), Australia (12%), Peru (10%), India (6.0%), United States (5.6%) and Mexico (5.0%), with Australia having the largest reserves. The world's largest zinc mine is the Red Dog open-pit zinc-lead-silver mine in Alaska, with 4.2% of world production. Major zinc mine operators include Vedanta Resources, Gl ...

Teck Resources
Teck Resources Limited, known as Teck Cominco until late 2008, is a diversified natural resources company headquartered in Vancouver, British Columbia, that is engaged in mining and mineral development, including coal for the steelmaking industry, copper, zinc, and energy. Secondary products include lead, silver, gold, molybdenum, germanium, indium and cadmium. Teck Resources was formed from the amalgamation of Teck and Cominco in 2001. In 2018, Teck Resources opened the C$17 billion Fort Hills oil sands project. In 2020, Teck abandoned plans for a second, larger C$20 billion open-pit petroleum-mine proposal—Frontier Mine— south of Wood Buffalo National Park and north of Fort McMurray in northeast Alberta. In 2020, a number of new executives were appointed to the company: Harry Conger as chief operating officer, Jonathan Price as chief financial officer, and Nicholas Hooper as senior vice president, corporate development.

Open-pit Mining
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburden is relatively thin or the material of interest is structurally unsuitable for tunnelling (as would be the case for cinder, sand, and gravel). In contrast, minerals that have been found underground but are difficult to retrieve due to hard rock, can be reached using a form of underground mining. To create an open-pit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting ea ...

Molybdenum
Molybdenum is a chemical element with the symbol Mo and atomic number 42 which is located in period 5 and group 6. The name is from Neo-Latin ''molybdaenum'', which is based on Ancient Greek ', meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of other metals) in 1778 by Carl Wilhelm Scheele. The metal was first isolated in 1781 by Peter Jacob Hjelm. Molybdenum does not occur naturally as a free metal on Earth; it is found only in various oxidation states in minerals. The free element, a silvery metal with a grey cast, has the sixth-highest melting point of any element. It readily forms hard, stable carbides in alloys, and for this reason most of the world production of the element (about 80%) is used in steel alloys, including high-strength alloys and superalloys. Most molybdenum compounds have low solubili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper Concentrate
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 Inco f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andes
The Andes, Andes Mountains or Andean Mountains (; ) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long, wide (widest between 18°S – 20°S latitude), and has an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. Along their length, the Andes are split into several ranges, separated by intermediate depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, El Alto and La Paz. The Altiplano plateau is the world's second-highest after the Tibetan plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes. The Andes Mountains are the highest m ...
