Minerals Separation, Limited
Minerals Separation Ltd, was a small London-based company involved in developing a technique of ore extraction. History Organized in 1903 by South African John Ballot, the firm moved to experiment with new processes as well as acquire patents of others until they had perfected a froth flotation process. This was perfected on Broken Hill, Australia mill tailings. By the 1910s, the firm's Australian process was generally accepted as so great an advance over any process known before that it promptly came into extensive use for the concentration of ores in most of the principal mining countries of the world. It largely replaced all earlier ore extraction processes and is today known as froth flotation. Its most important patent was the discovery that a small percentage of oil, agitated into a froth, was needed to make the process commercially successful at Broken Hill. The patent was received for this process in Britain in 1905 and then the next year around the world but especiall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Froth Flotation
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of Sulfide#Geology, sulfide ores". The development of froth flotation has improved the recovery of valuable minerals, such as copper- and lead-bearing minerals. Along with mechanized mining, it has allowed the economic recovery of valuable metals from much lower grade ore than previously. Industries Froth flotation is applied to a wide range of separations. An estimated 1B tons of materials are processed in this manner annually. Mineral processing Froth flotation is a process for separating minerals from gangue by exploiting differences in their hydrophobicity. Hydrophob ...

Broken Hill, Australia
Broken Hill is an inland mining city in the far west of outback New South Wales, Australia. It is near the border with South Australia on the crossing of the Barrier Highway (A32) and the Silver City Highway (B79), in the Barrier Range. It is 315m above sea level, with a hot desert climate, and an average rainfall of 235mm. The closest major city is Adelaide, the capital of South Australia, which is more than 500km to the southwest and linked via route A32. The town is prominent in Australia's mining, industrial relations and economic history after the discovery of silver ore led to the opening of various mines, thus establishing Broken Hill's recognition as a prosperous mining town well into the 1990s. Despite experiencing a slowing economic situation into the late 1990s and 2000s, Broken Hill itself was listed on the National Heritage List in 2015 and remains Australia's longest running mining town. Broken Hill, historically considered one of Australia's boomtowns, has been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ore Dressing
In the field of extractive metallurgy, mineral processing, also known as ore dressing, is the process of separating commercially valuable minerals from their ores. History Before the advent of heavy machinery the raw ore was broken up using hammers wielded by hand, a process called "spalling". Before long, mechanical means were found to achieve this. For instance, stamp mills were used in Samarkand as early as 973. They were also in use in medieval Persia. By the 11th century, stamp mills were in widespread use throughout the medieval Islamic world, from Islamic Spain and North Africa in the west to Central Asia in the east. A later example was the Cornish stamps, consisting of a series of iron hammers mounted in a vertical frame, raised by cams on the shaft of a waterwheel and falling onto the ore under gravity. The simplest method of separating ore from gangue consists of picking out the individual crystals of each. This is a very tedious process, particularly when the indi ...

Auguste De Bavay
Auguste Joseph François de Bavay (9 June 1856 – 16 November 1944) was a brewer and industrial chemist in Australia. History De Bavay was born in Vilvoorde, Belgium, second son of R. de Bavay, Knight of the Order of Leopold / a son of Xavier de Bavay and his wife Marie Thérèse de Bavay née de Bontridder. He was educated at a college in Namur, and graduated in 1873 qualified as a surveyor. He undertook further studies at Gembloux, and found employment as a brewer and chemist. In the late 1870s he left for Ceylon (present-day Sri Lanka), where he worked as a plantation manager. In March 1884 De Bavay arrived in Melbourne and worked as a brewer at Thomas Aitken's Victoria Parade Brewery. Following E. C. Hansen's discovery of the impact of yeast variety on the beer quality, De Bavay grew Australia's first pure yeast expressly cultured for top-fermentation brewing. His students included Jack Breheny. In 1894 De Bavay joined the Foster's Group following a recommendation by Monta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gangue
In mining, gangue () is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. It is thus distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed, and from tailings, which is rock already stripped of valuable minerals. The separation of valuable mineral from gangue minerals is known as mineral processing, mineral dressing, or ore dressing. It is a necessary, and often significant, aspect of mining. It can be a complicated process, depending on the nature of the minerals involved. For example, galena, an ore of lead, is usually found in large pieces within its gangue, so it does not normally need extensive processing to remove it; but cassiterite, the chief ore mineral of tin, is usually disseminated as very small crystals throughout its gangue, so when it is mined from hard rock, the ore-bearing rock first needs to be crushed ...

Daniel C
The Wake are a British post-punk, synth-pop and later indie pop band, formed in Glasgow in 1981 by Gerard "Caesar" McInulty (formerly of Altered Images), Steven Allen (drums) and Joe Donnelly (bass), the latter replaced by Bobby Gillespie. Steven's sister Carolyn Allen also joined on keyboards, and remained in the band thereafter. Gillespie left the band in 1983, replaced by Martin Cunning and then by Alexander 'Mac' Macpherson. History The Wake released their first single on their own Scan 45 label, coupling together "On Our Honeymoon" and "Give Up". This single eventually caught the attention of New Order (band), New Order manager Rob Gretton, who helped the band sign to Factory Records in 1982 and record an LP (''Harmony (The Wake album), Harmony'') at Strawberry Studios in Stockport. This was followed by a number of singles on Factory and its Belgian sister label Factory Benelux. In 1983, The Wake toured with New Order (band), New Order, and thus received critical attention ...

History Of Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and f ...
