Driefontein Mine
The Driefontein mine is a large mine located in the northern part of South Africa in Gauteng. Driefontein is an important gold producer and represents one of the largest uranium reserves in South Africa having estimated reserves of 238 million tonnes of ore grading 0.0053% uranium. History In 1937, aided by a magnetometer, Dr Rudolf Krahman discovered vast gold deposits of the West Wits Line near Carletonville South Africa, including those developed as the Driefontein and Kloof (later KDC) mines. In 1999, Gold Fields acquired Driefontein through the purchase AGA Aga or AGA may refer to: Business * Architectural Glass and Aluminum (AGA), a glazing contractor, established in 1970 * AGA (automobile), ''Autogen Gasaccumulator AG'', 1920s German car company *AGA AB, ''Aktiebolaget Svenska Gasaccumulator'', a ...’s 21.5% shareholding, then making Gold Fields the world’s second largest gold producer.

Gauteng
Gauteng ( ) is one of the nine provinces of South Africa. The name in Sotho-Tswana languages means 'place of gold'. Situated on the Highveld, Gauteng is the smallest province by land area in South Africa. Although Gauteng accounts for only 1.5% of the country's land area, it is home to more than a quarter of its population (26%). Highly urbanised, the province contains the country's largest city, Johannesburg, which is also one of the largest cities in the world. Gauteng is the wealthiest province in South Africa and is considered as the financial hub of not only South Africa but the entire African continent, mostly concentrated in Johannesburg. It also contains the administrative capital, Pretoria, and other large areas such as Midrand, Vanderbijlpark, Ekurhuleni and the affluent Sandton. Gauteng is the most populous province in South Africa with a population of approximately 16.1 million people according to mid year 2022 estimates. Etymology The name ''Gauteng'' is derived ...

Johannesburg
Johannesburg ( , , ; Zulu and xh, eGoli ), colloquially known as Jozi, Joburg, or "The City of Gold", is the largest city in South Africa, classified as a megacity, and is one of the 100 largest urban areas in the world. According to Demographia, the Johannesburg–Pretoria urban area (combined because of strong transport links that make commuting feasible) is the 26th-largest in the world in terms of population, with 14,167,000 inhabitants. It is the provincial capital and largest city of Gauteng, which is the wealthiest province in South Africa. Johannesburg is the seat of the Constitutional Court, the highest court in South Africa. Most of the major South African companies and banks have their head offices in Johannesburg. The city is located in the mineral-rich Witwatersrand range of hills and is the centre of large-scale gold and diamond trade. The city was established in 1886 following the discovery of gold on what had been a farm. Due to the extremely large gold de ...

South Africa
South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves the country Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 60 million people, the country is the world's 24th-most populous nation and covers an area of . South Africa has three capital cities, with the executive, judicial and legislative branches of government based in Pretoria, Bloemfontein, and Cape Town respectively. The largest city is Johannesburg. About 80% of the population are Black South Afri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uranium
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238 (99. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnetometer
A magnetometer is a device that measures magnetic field or magnetic dipole moment. Different types of magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location. A compass is one such device, one that measures the direction of an ambient magnetic field, in this case, the Earth's magnetic field. Other magnetometers measure the magnetic dipole moment of a magnetic material such as a ferromagnet, for example by recording the effect of this magnetic dipole on the induced current in a coil. The first magnetometer capable of measuring the absolute magnetic intensity at a point in space was invented by Carl Friedrich Gauss in 1833 and notable developments in the 19th century included the Hall effect, which is still widely used. Magnetometers are widely used for measuring the Earth's magnetic field, in geophysical surveys, to detect magnetic anomalies of various types, and to determine the dipole moment of magnetic materials.

Carletonville
Carletonville is a town in Gauteng and the seat of the Merafong City Local Municipality in the West Rand District Municipality in Gauteng, South Africa, just north of the richest gold-mining area in the world. At 3,749 m, Western Deep Levels holds the record for the world's deepest gold mine. History Developed by various mining companies from 1937 onwards, Carletonville was named after the long-serving mining director of Consolidated Gold Fields, Guy Carleton Jones, but was not officially incorporated until 1959. Upon reaching a population of 2000 1967, (mostly white inhabitants of the apartheid era) it became officially recognised and celebrated as a provincial town. There are several privately owned gold-mining township villages and contractor labour quarters established on mining ground owned by the various mining houses which operate in the area. The villages are located to the South of the R501 provincial road which forms the southern boundary of Carletonville. While the min ...

KDC Mine
The KDC mine, formerly the Kloof mine, is a large mine located in the northern part of South Africa in Gauteng, near Carletonville, and represents one of the largest uranium reserves in South Africa having estimated reserves of 256.4 million tonnes of ore grading 0.0036% uranium. In 2012, Gold Fields Limited unbundled its subsidiary, GFI Mining South Africa Proprietary Limited (“GFIMSA”), which was then renamed Sibanye Gold Limited (“Sibanye Gold”), and consisted of the KDC (formerly Kloof) and Beatrix mines, as well as an array of support service entities in South Africa. 2012 strike In the aftermath of the Marikana massacre, workers at KDC West – formerly known as the Driefontein mine and by then the west section of KDC – entered an unprotected strike on 9 September, seeking a wage increase, among other demands.
