Jubayt, Sudan
Jubayt or Gebeit is a small town in eastern Sudan. History Gold mining of quartz veins in the area dates from the New Kingdom of Egypt Period. A large New Kingdom settlement is located NE of the main Gebeit mine in Wadi Gebeir-Shariq, which includes 15 buildings, and numerous oval grinding mills and anvil stones. Mining was resumed under the British in 1903, after an evaluation by the Royal Geographic Society in 1896. Total gold production when operations ceased in 1956 was about 4,200 kg from 63.5 grams per ton (g/t) ore. Then, the British Minex Mineral (Sudan) operated for a time until 1990. Some archaic extraction of ore was still underway in the 2000s by miners living in the makeshift village. Climate Transport It is served by a station on the mainline of the Sudan railway network.

Sudan
Sudan ( or ; ar, السودان, as-Sūdān, officially the Republic of the Sudan ( ar, جمهورية السودان, link=no, Jumhūriyyat as-Sūdān), is a country in Northeast Africa. It shares borders with the Central African Republic to the southwest, Chad to the west, Egypt to the north, Eritrea to the northeast, Ethiopia to the southeast, Libya to the northwest, South Sudan to the south and the Red Sea. It has a population of 45.70 million people as of 2022 and occupies 1,886,068 square kilometres (728,215 square miles), making it Africa's List of African countries by area, third-largest country by area, and the third-largest by area in the Arab League. It was the largest country by area in Africa and the Arab League until the 2011 South Sudanese independence referendum, secession of South Sudan in 2011, since which both titles have been held by Algeria. Its Capital city, capital is Khartoum and its most populated city is Omdurman (part of the metropolitan area of Khar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quartz Vein
In geology, a vein is a distinct sheetlike body of crystallized minerals within a rock. Veins form when mineral constituents carried by an aqueous solution within the rock mass are deposited through precipitation. The hydraulic flow involved is usually due to hydrothermal circulation. Veins are classically thought of as being the ones in the body not the rock veins and arteries planar fractures in rocks, with the crystal growth occurring normal to the walls of the cavity, and the crystal protruding into open space. This certainly is the method for the formation of some veins. However, it is rare in geology for significant open space to remain open in large volumes of rock, especially several kilometers below the surface. Thus, there are two main mechanisms considered likely for the formation of veins: ''open-space filling'' and ''crack-seal growth''. Open space filling Open space filling is the hallmark of epithermal vein systems, such as a stockwork, in greisens or in c ...

New Kingdom Of Egypt
The New Kingdom, also referred to as the Egyptian Empire, is the period in ancient Egyptian history between the sixteenth century BC and the eleventh century BC, covering the Eighteenth, Nineteenth, and Twentieth dynasties of Egypt. Radiocarbon dating places the beginning of the New Kingdom between 1570 BC and 1544 BC. The New Kingdom followed the Second Intermediate Period and was succeeded by the Third Intermediate Period. It was Egypt's most prosperous time and marked the peak of its power. The concept of a "New Kingdom" as one of three "golden ages" was coined in 1845 by German Egyptologist Baron von Bunsen, and its definition would evolve significantly throughout the nineteenth and twentieth centuries. The later part of this period, under the Nineteenth and Twentieth dynasties (1292–1069 BC), is also known as the ''Ramesside period''. It is named after the eleven pharaohs who took the name Ramesses, after Ramesses I, the founder of the Nineteenth Dynasty. Possibly ...

Mills (grinding)
A mill is a device, often a structure, machine or kitchen appliance, that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes. There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind ( windmill) or water ( watermill). In modern era, they are usually powered by electricity. The grinding of solid materials occurs through mechanical forces that break up the structure by overcoming the interior bonding forces. After the grinding the state of the solid is changed: the grain size, the grain size disposition and the grain shape. Milling also refers to the process of breaking down, separating, sizing, or classifying aggregate material (e.g. mining ore). For instance rock crushing or grinding to produce uniform aggregate size for construction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anvil
An anvil is a metalworking tool consisting of a large block of metal (usually forged or cast steel), with a flattened top surface, upon which another object is struck (or "worked"). Anvils are as massive as practical, because the higher their inertia, the more efficiently they cause the energy of striking tools to be transferred to the work piece. In most cases the anvil is used as a forging tool. Before the advent of modern welding technology, it was the primary tool of metal workers. The great majority of modern anvils are made of cast steel that has been heat treated by either flame or electric induction. Inexpensive anvils have been made of cast iron and low quality steel, but are considered unsuitable for serious use as they deform and lack rebound when struck. Structure The primary work surface of the anvil is known as the face. It is generally made of hardened steel and should be flat and smooth with rounded edges for most work. Any marks on the face will b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Geographic Society
The Royal Geographical Society (with the Institute of British Geographers), often shortened to RGS, is a learned society and professional body for geography based in the United Kingdom. Founded in 1830 for the advancement of geographical sciences, the Society has 16,000 members, with its work reaching the public through publications, research groups and lectures. The Society was founded in 1830 under the name ''Geographical Society of London'' as an institution to promote the 'advancement of geographical science'. It later absorbed the older African Association, which had been founded by Sir Joseph Banks in 1788, as well as the Raleigh Club and the Palestine Association. In 1995 it merged with the Institute of British Geographers, a body for academic geographers, to officially become the Royal Geographical Society ''with IBG''. The society is governed by its Council, which is chaired by the Society's President, according to a set of statutes and standing orders. The members ...

Arabian-Nubian Shield
The Arabian-Nubian Shield (ANS) is an exposure of Precambrian crystalline rocks on the flanks of the Red Sea. The crystalline rocks are mostly Neoproterozoic in age. Geographically - and from north to south - the ANS includes parts of Israel, Jordan, Egypt, Saudi Arabia, Sudan, Eritrea, Ethiopia, Yemen, and Somalia. The ANS in the north is exposed as part of the Sahara Desert and Arabian Desert, and in the south in the Ethiopian Highlands, Asir province of Arabia and Yemen Highlands. The ANS was the site of some of man's earliest geologic efforts, principally by the ancient Egyptians to extract gold from the rocks of Egypt and NE Sudan. This was the most easily worked of all metals and does not tarnish. All of the gold deposits in Egypt and northern Sudan were found and exploited by Egyptians. The earliest preserved geologic map was made in 1150 BCE to show the location of gold deposits in Eastern Egypt; it is known as the Turin papyrus. New gold discoveries have been ...
