Vanadium is a chemical element with the symbol V and atomic number 23. It is a hard, silvery-grey, malleable transition metal. The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) somewhat stabilizes the free metal against further oxidation.
Brits is a town situated in a fertile citrus, vegetable and grain-producing area that is irrigated by the waters of the Hartbeespoort Dam in North West Province of South Africa. It is close to the City of Tshwane Metropolitan Municipality in Gauteng, which includes Pretoria, and it has the same dialling code as Pretoria. In addition to being a centre for agriculture, the city is home to several heavy industries. A factory of the Italian car manufacturer Alfa Romeo produced cars for the domestic market and export to Asia from 1974 to 1985. The city also plays an important role in the South African mining industry: 94% of South Africa's platinum comes from the Rustenburg and Brits districts, which together produce more platinum than any other single area in the world. In addition, there is a large vanadium mine in the district.
Barberton is a town in the Mpumalanga province of South Africa, which has its origin in the 1880s gold rush in the region. It is situated in the De Kaap Valley and is fringed by the Makhonjwa Mountains. It is 43 kilometres (27 mi) south of Mbombela and 360 kilometres (220 mi) east of Johannesburg.
Kitwe is the third largest city in terms of infrastructure development and second largest city in terms of size and population in Zambia. With a population of 517,543 Kitwe is one of the most developed commercial and industrial areas in the nation, alongside Ndola and Lusaka. It has a complex of mines on its north-western and western edges.
Lephalale is a coal mining town in the Limpopo province of South Africa immediately east of the Waterberg Coalfield. The town was established as Ellisras in 1960 and named after Patrick Ellis and Piet Erasmus who settled on a farm there in the 1930s. In 2002, Ellisras was renamed Lephalale by the provincial government of Limpopo, after the main river that crosses the municipality. Lephalale is divided into three main subsections, Ellisras, Onverwacht and Marapong. Lephalale is derived from the setswana language meaning "to flow".
Mokopane, also known as Potgietersrus, is a town in the Limpopo province of South Africa.
The Highveld is the portion of the South African inland plateau which has an altitude above roughly 1500 m, but below 2100 m, thus excluding the Lesotho mountain regions to the south-east of the Highveld. It is home to some of the country's most important commercial farming areas, as well as its largest concentration of metropolitan centres, especially the Gauteng conurbation, which accommodates one-third of South Africa's population.
The Bushveld is a sub-tropical woodland ecoregion of Southern Africa. It encompasses most of Limpopo Province and a small part of the North West Province of South Africa, the Central and North-East Districts of Botswana and the Matabeleland South and part of the Matabeleland North provinces of Zimbabwe. Kruger National Park in South Africa has a number of 'Bushveld' camps. The terms 'bushveld' and 'lowveld' are sometimes used interchangeably, and the line between the two is somewhat blurred, although the lowveld lies in Mpumalanga.
The vanadium redox battery (VRB), also known as the vanadium flow battery (VFB) or vanadium redox flow battery (VRFB), is a type of rechargeable flow battery. It employs vanadium ions as charge carriers. The battery uses vanadium's ability to exist in solution in four different oxidation states to make a battery with a single electroactive element instead of two. For several reasons, including their relative bulkiness, vanadium batteries are typically used for grid energy storage, i.e., attached to power plants/electrical grids.
The Solar Electric Light Fund (SELF) is a Washington, D.C. based nonprofit establishment whose mission is to design and implement solar energy solutions to assist those living in economic community with low level of energy, educational, health care, and agricultural development. Since 1990, SELF has completed projects in more than 20 countries, using solar energy to power drip irrigation in Benin, health care in Haiti, telemedicine in the Amazon rainforest, online learning in South Africa, and microenterprise development in Nigeria.
Anglo American Platinum Limited is the world's largest primary producer of platinum, accounting for about 38% of the world's annual supply.
A flow battery, or redox flow battery, is a type of electrochemical cell where chemical energy is provided by two chemical components dissolved in liquids that are pumped through the system on separate sides of a membrane. Ion exchange occurs through the membrane while both liquids circulate in their own respective space. Cell voltage is chemically determined by the Nernst equation and ranges, in practical applications, from 1.0 to 2.43 volts.
The Bushveld Igneous Complex (BIC) is the largest layered igneous intrusion within the Earth's crust. It has been tilted and eroded forming the outcrops around what appears to be the edge of a great geological basin: the Transvaal Basin. It is approximately 2 billion years old and is divided into four different limbs: the northern, southern, eastern, and western limbs. The Bushveld Complex comprises the Rustenburg Layered suite, the Lebowa Granites and the Rooiberg Felsics, that are overlain by the Karoo sediments. The site was first discovered around 1897 by Gustaaf Molengraaff.
The Waterberg is a mountainous massif of approximately 654,033 hectare in north Limpopo Province, South Africa. The average height of the mountain range is 600 m with a few peaks rising up to 2000 m above sea level. Vaalwater town is located just north of the mountain range. The extensive rock formation was shaped by hundreds of millions of years of riverine erosion to yield diverse bluff and butte landform. The ecosystem can be characterised as a dry deciduous forest or Bushveld. Within the Waterberg there are archaeological finds dating to the Stone Age, and nearby are early evolutionary finds related to the origin of humans.
Mining in South Africa was once the main driving force behind the history and development of Africa's most advanced and richest economy. Large-scale and profitable mining started with the discovery of a diamond on the banks of the Orange River in 1867 by Erasmus Jacobs and the subsequent discovery and exploitation of the Kimberley pipes a few years later. Gold rushes to Pilgrim's Rest and Barberton were precursors to the biggest discovery of all, the Main Reef/Main Reef Leader on Gerhardus Oosthuizen's farm Langlaagte, Portion C, in 1886, the Witwatersrand Gold Rush and the subsequent rapid development of the gold field there, the biggest of them all.
Tsogo Convent School is a private Roman Catholic, English medium, High School located in Mmakau north west of the city of Tshwane, in the North West Province of South Africa. It is primarily run by the Sisters of Mercy.
Husk Power Systems, founded in 2008, is a company based in Fort Collins, Colorado, US, that provides clean energy services to off-grid or weak grid rural communities in East Africa, West Africa and South Asia, primarily by building renewable energy mini-grids/micro-grids. Its original technology generated electricity using a biomass gasifier that created fuel from rice husks, a waste product of rice hullers that separate the husks as chaff from the rice, a staple food in both Asia and Africa. In the mid-2010s, with the rapid decline in the price of solar PV and batteries, Husk pivoted its business model to focus more on solar-plus-storage mini-grids, while continuing to use biomass in combination with solar to serve communities with larger electricity demand. In 2021, Husk Power was recognized in the REN21 Renewables Global Status Report as the first mini-grid company to achieve significant scale, by surpassing 100 solar hybrid community mini-grids, and 5,000 small business customers. In 2022, Husk signed an Energy Compact with the United Nations, in which it set a target of building 5,000 mini-grids and connecting 1 million customers by 2030.
William Bleloch was a South African metallurgist noted for developing smelting techniques for the processing of chrome ores. At a 1975 ceremony when the University of the Witwatersrand conferred upon him an honorary doctorate of Science and Engineering, the citation read "William Bleloch can truly be called the father of our electrochemical and electrometallurgical industries".
