Simmer And Jack
Simmer and Jack Mines Ltd (until 1924 known as The Simmer & Jack Gold Mining Co. Ltd.) is a South African company which was founded in 1887 by the German August Simmer and Scotsman John Jack, shortly thereafter selling the majority shareholding to Gold Fields of South Africa Ltd. The company was listed until 2013 at the Johannesburg Stock Exchange. History In February 1886, the discovery of gold on the Witwatersrand in South Africa led to the founding of the city of Johannesburg shortly thereafter. The farm Elandsfontein was about ten kilometers east and belonged to a farmer, Sarel Meyer. Simmer & Jack, a trading company in Harrismith which ran a shop in Chrissiesmeer had, a year earlier, acquired half of Meyer's farm. In September 1886 John Jack registered the mining rights on the farm to Simmer & Jack. With the founding of the company in August 1887 Simmer and Jack took on board the entrepreneur Sir George Farrar, whose family imported drilling equipment to South Africa. Also ...

Germiston
Germiston, also known as kwaDukathole, is a small city in the East Rand region of Gauteng, South Africa, administratively forming part of the City of Ekurhuleni Metropolitan Municipality since the latter's establishment in 2000. It functions as the municipal seat of Ekurhuleni, hosting the municipal council and administration. History Germiston was established in the early days of the Witwatersrand Gold Rush, gold rush when two prospectors, John Jack from the farm of Germiston, Glasgow, Germiston near Glasgow and August Simmer from Vacha, Germany, Vacha in Germany, struck paydirt on the farm of ''Elandsfontein''. In August 1887, the pair were on their way to the Eastern Transvaal when they ''outspanned'' (rested their pack animals) on the farm ''Elandsfontein'' and decided to stay and buy the land. Both men made fortunes and the town sprang up 2 km from the Simmer and Jack mine named after Jack's fathers farm. In 1921, the world's largest gold refinery, the Rand Refine ...

Gold Mining In South Africa
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. Diamond and gold production are now well down from their peaks, though South Africa is still number 5 in gold but remains a cornucopia of mineral riches. It is the world's largest producer of chrome, manganese, platinum, vanadium and vermiculite. It is the second largest producer of ilmenite, palladium, rutile and zirconium. It ...

Stamp Mill
A stamp mill (or stamp battery or stamping mill) is a type of mill machine that crushes material by pounding rather than grinding, either for further processing or for extraction of metallic ores. Breaking material down is a type of unit operation. Description A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft. As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam. Each one frame and stamp set is sometimes called a "battery" or, confusingly, a "stamp" and mills are sometimes categorised by how many stamps they have, i.e. a "10 stamp mill" has 10 sets. They usually are arranged linearly, but when a mill is enlarged, a new line of them may be constructed rather than extending the line. Abandoned mill sites (as ...

Second Boer War
The Second Boer War ( af, Tweede Vryheidsoorlog, , 11 October 189931 May 1902), also known as the Boer War, the Anglo–Boer War, or the South African War, was a conflict fought between the British Empire and the two Boer Republics (the South African Republic and the Orange Free State) over the Empire's influence in Southern Africa from 1899 to 1902. Following the discovery of gold deposits in the Boer republics, there was a large influx of "foreigners", mostly British from the Cape Colony. They were not permitted to have a vote, and were regarded as "unwelcome visitors", invaders, and they protested to the British authorities in the Cape. Negotiations failed and, in the opening stages of the war, the Boers launched successful attacks against British outposts before being pushed back by imperial reinforcements. Though the British swiftly occupied the Boer republics, numerous Boers refused to accept defeat and engaged in guerrilla warfare. Eventually, British scorched eart ...

Jameson Raid
The Jameson Raid (29 December 1895 – 2 January 1896) was a botched Raid (military), raid against the South African Republic (commonly known as the Transvaal) carried out by British colonial administrator Leander Starr Jameson, under the employment of Cecil Rhodes. It involved 500 British South Africa Company police launched from Rhodesia (region), Rhodesia over the New Year weekend of 1895–96. Paul Kruger, whom Rhodes had a great personal hatred towards, was president of the South African Republic at the time. The raid was intended to trigger an uprising by the primarily British expatriate workers (known as Uitlanders) in the South African Republic, Transvaal but failed to do so. The workers were called the Johannesburg conspirators. They were expected to recruit an army and prepare for an insurrection; however, the raid was ineffective, and no uprising took place. The results included embarrassment of the British government; the replacement of Cecil Rhodes as prime minister ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold Cyanidation
Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction. Cyanidation is also widely used in the extraction of silver, usually after froth flotation. Production of reagents for mineral processing to recover gold represents more than 70% of cyanide consumption globally. Other metals are recovered from the process include copper, zinc, and silver, but gold is the main driver of this technology. Due to the highly poisonous nature of cyanide, the process is controversial and its use is even banned in some parts of the world. Cyanide can be safely used in the gold mining industry. A key feature for safe use of cyanide is to ensure adequate pH control at an alkaline pH level above 10.5. At industrial scale, pH control is mainly achieved using lime, as an ...

John Seward MacArthur
John Stewart MacArthur was a chemist from Glasgow. Born on 9 December 1856, he is credited with the development of the gold cyanidation, MacArthur-Forrest cyanidation process in 1887, used to extract gold in South Africa. His patent for the process was voided. With the long-lasting legal issues about the cyanidation patents, MacArthur turned to other businesses. First, he investigated vanadium extraction from ore containing significant amounts of radium. From this enterprise he turned to the production of radium. He founded the Radium Works in Halton in 1911. In 1915 he moved it to Balloch, West Dunbartonshire and renamed it as Loch Lomond Radium Works. MacArthur died on 16 March 1920, aged 63.

Charles Rudd
Charles Dunell Rudd (22 October 1844 – 15 November 1916) was the main business associate of Cecil Rhodes. Early life He was born at Hamworth Hall, Northamptonshire, the son of Henry Rudd (1809–1884), who had a shipbuilding business in London, and his first wife Mary Stanbridge. Rudd studied at Harrow School (1857–1862) and then entered Trinity College, Cambridge in 1863, where he excelled in playing rackets. He left for Cape Colony in 1865 before completing his degree, according to himself under medical advice. There he hunted with the likes of John Dunn and endeavored in various business enterprises. In the early 1870s, he worked for his brother Thomas' (1831–1902) Port Elizabeth-based trading firm. Partnership with Cecil Rhodes In 1872/3 Rudd and Rhodes became friends and partners, working diamond claims in Kimberley, dealing in diamonds and operating pumping and ice-making machinery, amongst many other odds and ends. Between 1873 and 1881, while Rhodes intermit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cecil Rhodes
Cecil John Rhodes (5 July 1853 – 26 March 1902) was a British mining magnate and politician in southern Africa who served as Prime Minister of the Cape Colony from 1890 to 1896. An ardent believer in British imperialism, Rhodes and his British South Africa Company colonised the southern African territory of Rhodesia (now Zimbabwe and Zambia), which the company named after him in 1895. South Africa's Rhodes University is also named after him. He also devoted much effort to realising his vision of a Cape to Cairo Railway through British territory. Rhodes set up the provisions of the Rhodes Scholarship, which is funded by his estate. The son of a vicar, Rhodes was born at Netteswell House, Bishop's Stortford, Hertfordshire. A sickly child, he was sent to South Africa by his family when he was 17 years old in the hope that the climate might improve his health. He entered the diamond trade at Kimberley in 1871, when he was 18, and, thanks to funding from Rothschild & Co, beg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roodepoort
Roodepoort is a town in the Gauteng province of South Africa. Formerly an independent municipality, Roodepoort became part of the Johannesburg municipality in the late 1990s, along with Randburg and Sandton. Johannesburg's most famous botanical garden, Witwatersrand National Botanical Gardens (now renamed Walter Sisulu National Botanical Garden), is located in Roodepoort. History In 1884, brothers Fred and Harry Struben, having discovered gold on the farm Wilgespruit at the western end of the Witwatersrand, were granted concessions to mine the area. When George Harrison's find at ''Langlaagte'' came to light and gold fever took hold, the Strubens brothers were joined by a swarm of gold diggers. Other areas such as ''Maraisburg'' were prospected and mined by A.P. Marais and at ''Florida'', the owners were van der Hoven, Bantjies and Lys. Though the Struben brothers' ''Confidence Reef'' bore little gold and their mine was unprofitable, the ramshackle town that grew around it becam ...
