Cireșata Mine
The Cireșata mine is a large open pit mine in the west of Romania in Hunedoara County, north of Deva and northwest of the capital, Bucharest. Cireșata represents a large gold and copper deposit with estimated reserves of 4.18 million oz of gold and 174.4 million tonnes of copper ore grading 0.15% copper. The project is owned by the Toronto-based company Carpathian Gold. The project will involve the mining and processing of 7.1 million tonnes of ore per annum over an open pit life of 19 years. The open pit is expected to yield approximately 155,000 oz of gold and 10,000 tonnes of copper per year in doré, reflecting an average total process recovery of 68% for gold and approximately 91% for copper Copper is a chemical element; it has symbol Cu (from Latin ) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orang .... References External links ...

Counties Of Romania
A total of 41 counties (), along with the municipality of Bucharest, constitute the official administrative divisions of Romania. They represent the country's NUTS-3 (Nomenclature of Territorial Units for Statistics – Level 3) statistical subdivisions within the European Union and each of them serves as the local level of government within its borders. Most counties are named after a major river, while some are named after notable cities within them, such as the county seat. The earliest organization into ''județe'' of the Principalities of Wallachia and Moldavia (where they were termed ''ținuturi'') dates back to at least the late 14th century. For most of the time since modern Romania was formed in 1859, the administrative division system has been similar to that of the French departments. The system has since changed several times and the number of counties has varied over time, from the 71 ''județe'' that existed before World War II to only 39 after 1968. The curr ...

Open Pit
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique that extracts rock or minerals from the earth. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface where the overburden is relatively thin. In contrast, deeper mineral deposits can be reached using underground mining. Open-pit mining is considered one of the most dangerous sectors in the industrial world. It causes significant effects to miners' health, as well as damage to the ecological land and water. Open-pit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths. Additionally, open-pit produces harmful pollutants depending on the type of mineral being mined, and the type of mining process being used. Extraction Miners typically drill a series of test holes to locate an underground ore body. From ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mining
Mining is the Resource extraction, extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agriculture, agricultural processes, or feasibly created Chemical synthesis, artificially in a laboratory or factory. Ores recovered by mining include Metal#Extraction, metals, coal, oil shale, gemstones, limestone, chalk mining, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even fossil water, water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final mine reclamation, reclamation or restoration of the land after the mine is closed.

Deva, Romania
Deva (; Hungarian: ''Déva'', Hungarian pronunciation: ; German: ''Diemrich'', ''Schlossberg'', ''Denburg''; Latin: ''Sargetia''; is a city in Romania, in the historical region of Transylvania, on the left bank of the river Mureș. It is the capital of Hunedoara County. Name Its name was first recorded in 1269 as castrum ''Dewa''. The origin of the name gave rise to controversy. It is considered that the name comes from the ancient Dacian word ''dava'', meaning "fortress" (as in ''Pelendava'', ''Piroboridava'', or ''Zargidava''). Other theories trace the name to a Roman Legion, the Legio II Augusta, transferred to Deva from Castrum Deva, now Chester ('' Deva Victrix'') in Britain. János András Vistai assume the name is of old Turkic origin from the name Gyeücsa. Others assert that the name is probably of Slavic origin where ''Deva'' or ''Devín'' means "girl" or "maiden" (a similar case exists in Slovakian for the Devín Castle, located at the confluence of the Danu ...

Gold
Gold is a chemical element; it has chemical symbol Au (from Latin ) and atomic number 79. In its pure form, it is a brightness, bright, slightly orange-yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal, a group 11 element, and one of the noble metals. It is one of the least reactivity (chemistry), reactive chemical elements, being the second-lowest in the reactivity series. It is solid under standard temperature and pressure, standard conditions. Gold often occurs in free elemental (native state (metallurgy), native state), as gold nugget, nuggets or grains, in rock (geology), rocks, vein (geology), veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as in electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper
Copper is a chemical element; it has symbol Cu (from Latin ) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable, unalloyed metallic form. This means that copper is a native metal. This led to very early human use in several regions, from . Thousands of years later, it was the first metal to be smelted from sulfide ores, ; the first metal to be cast into a shape in a mold, ; and the first metal to be purposely alloyed with another metal, tin, to create bronze, ...
