Mining In Egypt
Mining in Egypt has had a long history that dates back to predynastic times. Active mining began in Egypt around 3000 BCE. Egypt has substantial mineral resources, including 48 million tons of tantalite (fourth largest in the world), 50 million tons of coal, and an estimated 6.7 million ounces of gold in the Eastern Desert. The total real value of minerals mined was about ( US$18.7 million) in 1986, up from (US$11 million) in 1981. ''This article incorporates text from the source, which is in the public domain.'' The chief minerals in terms of volume output were iron ore, phosphates, and salt. The quantities produced in 1986 were estimated at 2,048, 1,310, and 1,233 tons, respectively, compared with 2,139, 691, and 883 tons in 1981. In addition, minor amounts of asbestos (313 tons) and quartz (19 tons) were mined in 1986. Preliminary exploration in Sinai indicated the presence of zinc, tin, lead, and copper deposits.

Quartz
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The atoms are linked in a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at . Since the transformation is accompanied by a significant change in volume, it can easily induce microfracturing of ceramics or rocks passing through this temperature threshold. There are many different varieties of quartz, several of which are classified as gemstones. Since antiquity, varieties of quartz have been the most commonly used minerals in the making of jewelry and hardstone carvings, especially in Eurasia. Quartz is the mineral defining the val ...

Alluvial
Alluvium (from Latin ''alluvius'', from ''alluere'' 'to wash against') is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit. Alluvium is typically geologically young and is not consolidated into solid rock. Sediments deposited underwater, in seas, estuaries, lakes, or ponds, are not described as alluvium. Floodplain alluvium can be highly fertile, and supported some of the earliest human civilizations. Definitions The present consensus is that "alluvium" refers to loose sediments of all types deposited by running water in floodplains or in alluvial fans or related landforms. However, the meaning of the term has varied considerably since it was first defined in the French dictionary of Antoine Furetière, posthumously published in 1690. Drawing upon concepts from Roman law, Furetière defined ''alluvion'' (the F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wadi Hammamat
Wadi Hammamat ( en, Valley of Many Baths, ''India way; gateway to India'') is a dry river bed in Egypt's Eastern Desert, about halfway between Al-Qusayr and Qena. It was a major mining region and trade route east from the Nile Valley in ancient times, and three thousand years of rock carvings and graffiti make it a major scientific and tourist site today. Trade route Hammamat became the major route from Thebes to the Red Sea and then to the Silk Road that led to Asia, or to Arabia and the horn of Africa. This 200 km journey was the most direct route from the Nile to the Red Sea, as the Nile bends toward the coast at the western end of the wadi. The Hammamat route ran from Qift (or Coptos), located just north of Luxor, to Al-Qusayr on the coast of the Red Sea. Qift was an important center for administration, religion, and commerce. The cities at both ends of the route were established by the First Dynasty, although evidence of predynastic occupation also has been found ...

Ramesside Period
The Twentieth Dynasty of Egypt (notated Dynasty XX, alternatively 20th Dynasty or Dynasty 20) is the third and last dynasty of the Ancient Egyptian New Kingdom period, lasting from 1189 BC to 1077 BC. The 19th and 20th Dynasties furthermore together constitute an era known as the ''Ramesside period''. This dynasty is generally considered to be the start of the decline of Ancient Egypt. History Background Upon the death of the last pharaoh of the 19th Dynasty, Queen Twosret, Egypt descended into a period of civil war, as attested by the Elephantine stela built by Setnakhte. The circumstances of Twosret's demise are uncertain, as she may have died peacefully during her reign or been overthrown by Setnakhte, who was likely already middle aged at the time. 20th Dynasty A consistent theme of this dynasty was the loss of pharaonic power to the High Priests of Amun. Horemheb, a pharaoh of the 18th Dynasty, had restored the traditional Ancient Egyptian religion and the priesthood of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Egypt
Upper Egypt ( ar, صعيد مصر ', shortened to , , locally: ; ) is the southern portion of Egypt and is composed of the lands on both sides of the Nile that extend upriver from Lower Egypt in the north to Nubia in the south. In ancient Egypt, Upper Egypt was known as ''tꜣ šmꜣw'', literally "the Land of Reeds" or "the Sedgeland". It is believed to have been united by the rulers of the supposed Thinite Confederacy who absorbed their rival city states during the Naqada III period (c. 3200–3000 BC), and its subsequent unification with Lower Egypt ushered in the Early Dynastic period. Upper and Lower Egypt became intertwined in the symbolism of pharaonic sovereignty such as the Pschent double crown. Upper Egypt remained as a historical region even after the classical period. Geography Upper Egypt is between the Cataracts of the Nile beyond modern-day Aswan, downriver (northward) to the area of El-Ayait, which places modern-day Cairo in Lower Egypt. The northern (d ...

Gold Mining
Gold mining is the extraction of gold resources by mining. Historically, mining gold from alluvial deposits used manual separation processes, such as gold panning. However, with the expansion of gold mining to ores that are not on the surface, has led to more complex extraction processes such as pit mining and gold cyanidation. In the 20th and 21st centuries, most volume of mining was done by large corporations, however the value of gold has led to millions of small, artisanal miners in many parts of the Global South. Like all mining, human rights and environmental issues are common issues in the gold mining industry. In smaller mines with less regulation, health and safety risks are much higher. History The exact date that humans first began to mine gold is unknown, but some of the oldest known gold artifacts were found in the Varna Necropolis in Bulgaria. The graves of the necropolis were built between 4700 and 4200 BC, indicating that gold mining could be at least 700 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sukari
The Sukari mine or Alsukari mine (Arabic: السكري ''Al-Sukkari'', Egyptian Arabic, Egyptian pronunciation: ''El-Sokkari'') is a gold mine located in the Nubian Desert/Eastern Desert near the Red Sea in Egypt, in the south-east of the country in the Red Sea Governorate, 30 km south of Marsa Alam. It is exploited jointly by the Ministry of Petroleum and Mineral Resources (Egypt), Egyptian Ministry of Mineral Resources and Centamin. It is Egypt's first modern gold mine, an industry considered to have scope for expansion in the country. Egypt was known in the ancient world as being a source of gold, and one of the earliest available maps shows a gold mine at this location. It is a combination of an open-pit mining, open-pit mine and an underground mine, with estimated reserves of 15.4 million ounces of gold. The site is supplied by a 30 km long pipeline transport, pipeline bringing water from the Red Sea. History The $265-million project began gold production in 2009 ...

Copper
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 ...
