Sao Domingos Mine
The São Domingos Mine is a deserted open-pit mine in Corte do Pinto, Alentejo, Portugal. This site is one of the volcanogenic massive sulfide ore deposits in the Iberian Pyrite Belt, which extends from the southern Portugal into Spain. It was the first place in Portugal to have electric lighting. History The Romans mined in the São Domingos area for gold and silver for about 400 years. Mining stopped here when the Romans left. In 1854 Nicolau Biava, an Italian miner from Piedmont, Italy, staked a claim to the mine; ownership then passed to a French syndicate. In 1855 mining was resumed, as the international demand for copper grew during the Industrial Revolution. In 1859 the mining concession was leased for 50 years to an English mining company, Mason and Barry, run by Sir Francis Barry, 1st Baronet and his brother-in-law James Mason, because of their industrial mining expertise. The nearby port of Pomarão was inaugurated the same year. Known as Pomaron in England, thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alentejo
Alentejo ( , ) is a geographical, historical, and cultural region of south–central and southern Portugal. In Portuguese, its name means "beyond () the Tagus river" (''Tejo''). Alentejo includes the regions of Alto Alentejo and Baixo Alentejo. It corresponds to the districts of Beja, Évora, Portalegre, and Alentejo Litoral. Its main cities are Évora, Beja, Sines, Serpa, Estremoz, Elvas, and Portalegre. It has borders with Beira Baixa in the north, with Spain (Andalucia and Extremadura) in the east, Algarve in the south, and the Atlantic Ocean, Ribatejo, and Estremadura in the west. Alentejo is a region known for its traditional polyphonic singing groups, similar to those found in Tuscany, Corsica, and elsewhere. History The comarca of the Alentejo became the Alentejo Province, divided into upper (Alto Alentejo Province) and lower (Baixo Alentejo Province) designations. The modern NUTS statistical region, Alentejo Region, was expropriated from the medieval provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Guadiana
The Guadiana River (, also , , ), or Odiana, is an international river defining a long stretch of the Portugal-Spain border, separating Extremadura and Andalusia (Spain) from Alentejo and Algarve (Portugal). The river's basin extends from the eastern portion of Extremadura to the southern provinces of the Algarve; the river and its tributaries flow from east to west, then south through Portugal to the border towns of Vila Real de Santo António (Portugal) and Ayamonte (Spain), where it flows into the Gulf of Cádiz. With a course that covers a distance of , it is the fourth-longest in the Iberian peninsula, and its hydrological basin extends over an area of approximately (the majority of which lies within Spain). Etymology The Romans referred to the river as the , the "River of Ducks". During the Moorish occupation and settlement, the name was extended and referred to as ''Wadi Ana'' ('' wādī'' being the Arab term for "river"), later passed on to Portuguese and Spanish set ...

Open-pit Mines
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 eac ...

Copper Mines In Portugal
Copper is a chemical element with the symbol Cu (from la, cuprum) 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 metallic form (native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create bronze, c. ...

Buildings And Structures In Beja District
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 artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mediterranean Climate
A Mediterranean climate (also called a dry summer temperate climate ''Cs'') is a temperate climate sub-type, generally characterized by warm, dry summers and mild, fairly wet winters; these weather conditions are typically experienced in the majority of Mediterranean-climate regions and countries, but remain highly dependent on proximity to the ocean, altitude and geographical location. This climate type's name is in reference to the coastal regions of the Mediterranean Sea within the Mediterranean Basin, where this climate type is most prevalent. The "original" Mediterranean zone is a massive area, its western region beginning with the Iberian Peninsula in southwestern Europe and coastal regions of northern Morocco, extending eastwards across southern Europe, the Balkans, and coastal Northern Africa, before reaching a dead-end at the Levant region's coastline. Mediterranean climate zones are typically located along the western coasts of landmasses, between roughly 30 and 45 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulphuric Acid
Sulfuric acid (American spelling and the preferred IUPAC name) or sulphuric acid ( Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with the molecular formula . It is a colorless, odorless and viscous liquid that is miscible with water. Pure sulfuric acid does not exist naturally on Earth due to its strong affinity to water vapor; it is hygroscopic and readily absorbs water vapor from the air. Concentrated sulfuric acid is highly corrosive towards other materials, from rocks to metals, since it is an oxidant with powerful dehydrating properties. Phosphorus pentoxide is a notable exception in that it is not dehydrated by sulfuric acid, but to the contrary dehydrates sulfuric acid to sulfur trioxide. Upon addition of sulfuric acid to water, a considerable amount of heat is released; thus the reverse procedure of adding water to the acid should not be performed since the heat released may boil ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
