Grootegeluk Coal Mine
The Grootegeluk Coal Mine is an open cast coal mine within the Waterberg Coalfield of the Limpopo province of South Africa. It is operated by Exxaro. The mine is from Lephalale, and employs 2,000 people. Discovery In 1920, coal was found in the Ellisras Basin, but at first little was done to investigate the size of the resource. Between 1941 and 1952, 143 diamond-drill holes and two prospecting shafts were sunk to obtain a geological map of the Waterberg coalfield. In 1957 Iscor (later unbundled into Kumba Resources and Mittal Steel South Africa) bought surface rights on six farms located in the coalfield. In 1973 Iscor began detailed exploration of the deposits below the farms to determine the quality and quantity of coal. In 1979 Iscor obtained the mining leases on the farms and in 1980 established the Grootegeluk Coal Mine. The mine contains semi-soft coking coal, thermal coal and metallurgical coal. There is estimated to be 2,800 Mt of accessible coal out of a to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exxaro
Exxaro Resources Limited (Exxaro, the company or the group) is a South Africa-based diversified resources company with a robust coal business and acquisitive growth prospects in minerals and energy solutions. Exxaro is among the top five coal producers in South Africa. The company is listed on the Johannesburg Stock Exchange and at 31 December 2021, had assets of R75.7 billion and a market capitalisation of R53.4 billion. Exxaro Resources Ltd has been approved for a secondary listing on A2X Markets on Thursday, 2 April 2020.

Medupi
Medupi Power Station is a dry-cooled coal-fired power station built by Eskom near Lephalale in Limpopo province, South Africa. The name chosen for the station, Medupi, is a Sepedi word which means "gentle rain". With an installed capacity of 4,764 MW, when fully operational it should be the 8th largest coal-fired power station in the world. Original concept Medupi was conceived as Project Alpha in 2007, with only three units planned to total 2,400 MW and estimated cost of R32 billion. The design was changed at a late stage in 2007 and doubled in size to 4,764 MW. The boilers were envisaged to be supercritical in type, which would make them 38% more effective than other Eskom power stations. A dry cooled system was also intended to use less water than other coal-fired power stations in the fleet. Initial project costing was estimated at R69 billion but that was updated to approximately R80 billion by 2007. Parsons Brinckerhoff was appointed as the project engineer to oversee al ...

Coal Mines In South Africa
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Of Richards Bay
The Port of Richards Bay is located in Richards Bay harbour on the Indian Ocean coast of South Africa, and contains the Richards Bay Coal Terminal (RBCT) which is the largest coal export facility in Africa. Although originally built to handle coal exports, the port has become South Africa's premier bulk port, handling other dry bulk in addition to coal, as well as liquid bulk and breakbulk cargoes. It is also South Africa's most modern port. History The idea for a new harbour north of Durban began as far back as 1902 when a Cathcart W. Methen, Harbour Engineer, Durban, conducted a survey and advised the Natal Colony government in 1903, that Richards Bay would be a better choice than St Lucia., The idea was again revised in 1921 when a proposed harbour was investigated by a group of engineers at Kosi or Sodwana Bay's., Sodwana's suitability was again investigated in 1922 by Sir George Buchanan. The two former bays were again investigated in 1923, this time by Jan Smuts. The ide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Matimba Power Station
Matimba Power Station close to Ellisras, Limpopo Province, South Africa, is a dry-cooled coal-fired power plant operated by Eskom. Power generation The station consists of six 665 MW units with a total installed capacity of 3,990 MW. Turbine Maximum Continuous Rating is 35.60%. The power station was commissioned between 1988 and 1993. Matimba is the largest direct dry-cooled power station in the world. The use of dry-cooling technology has considerably reduced water consumption at the plant relative to those using wet-cooling systems. Matimba is fueled by the open cast Grootegeluk coal mine on the Waterberg Coalfield with about 14.6 million tons of coal a year via a conveyor system. The mine is also contracted to supply the new Medupi Power Station.

Eskom
Eskom Hld SOC Ltd or Eskom is a South African electricity public utility. It was established in 1923 as the Electricity Supply Commission (ESCOM) and was also known by its Afrikaans name Elektrisiteitsvoorsieningskommissie (EVKOM). Eskom represents South Africa in the Southern African Power Pool. The utility is the largest producer of electricity in Africa, and was among the top utilities in the world in terms of generation capacity and sales, but due to the ANC and incompetence has since slipped in both categories. It is the largest of South Africa's state owned enterprises. Eskom operates a number of notable power stations, including Matimba Power Station and Medupi Power Station in Lephalale, Kusile Power Station in Witbank, Kendal Power Station, and Koeberg Nuclear Power Station in the Western Cape Province, the only nuclear power plant in Africa. The company is divided into Generation, Transmission and Distribution divisions, and together Eskom generates approximately ...

Tailings
In mining, tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are different to overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to concentrate the valuable minerals, or hard rock mining, which pulverizes the rock containing the ore and then relies on chemical reactions to concentrate the sought-after material. In the latter, the extraction of minerals from ore requires comminution, i.e., grinding the ore into fine particles to facilitate extraction of the target element(s). Because of this comminution, tailings consist of a slurry of fine particles, ranging from the size of a grain of sand to a few micrometres. Mine tailings are usually produced from the mill in slurry form, which i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Haulpak
Haulpak was a very successful line of off-highway mining trucks. The name was used from 1953 until around 1999; the line continues under the Komatsu name. The name was adopted as Wabco Haulpak when R. G. LeTourneau's business was bought by Wabco, and the Haulpak name continued through Wabco's purchase by American Standard, the operation's purchase by Dresser Industries, the merger into Komatsu-Dresser, and for a time after Komatsu took over complete ownership from Dresser. History The origins of the Haulpak line began with the purchase of R. G. LeTourneau's construction machinery business in 1953 by Westinghouse Air Brake Company. Wabco had traditionally been a manufacturer of railway air brake systems, but ventured into construction machinery with the purchase of LeRoi air tools and industrial drills in 1952. The subsequent purchase of R. G. LeTourneau's construction machinery line gave Wabco a comprehensive range of machinery including scrapers, rubber-tyred dozers and ...
