The Jameson Cell is a high-intensity froth flotation cell that was invented by Laureate Professor Graeme Jameson of the University of Newcastle (Australia) and developed in conjunction with Mount Isa Mines Limited ("MIM", a subsidiary of MIM Holdings Limited and now part of the Glencore Xstrata group of companies).〔G J Jameson, G Harbort and N Riches, "The development and application of the Jameson Cell," in: ''Fourth Mill Operators' Conference, Burnie, Tasmania, 10–14 March 1991'' (The Australasian Institute of Mining and Metallurgy: Melbourne, 1991), 45–50.〕 ==Introduction== The high intensity of the Jameson Cell means that it is much shorter than conventional column flotation cells (see Figure 1), and it does not require air compressors to aerate the suspension of ground ore particles and water (known as a ''slurry'' or ''pulp'') in the flotation cell.〔G J Jameson, "Flotation cell development," in: ''The AusIMM Annual Conference, Broken Hill, New South Wales, 17–21 May 1992'' (The Australasian Institute of Mining and Metallurgy: Melbourne, 1992), 25–31.〕 The lack of a requirement for compressed air and the lack of moving parts means that power consumption is less than for the equivalent mechanical or conventional column flotation cell.〔M F Young, K E Barnes, G S Anderson and J D Pease, ("Jameson Cell: the ‘comeback' in base metals applications using improved design and flow sheets," ) in: ''Proceedings of the 38th Annual Canadian Mineral Processors Conference, Ottawa, Ontario, 17–19 January 2006'', (Canadian Institute of Mining, Metallurgy and Petroleum), 311–332. Accessed 23 May 2013.〕 In contrast to most types of flotation cell, the Cell introduces the feed and the air to the Cell in a combined stream via one or more cylindrical columns referred to as "downcomers". Other types of flotation cell typically introduce the feed and the air separately to the cell.〔 The Cell produces fast mineral flotation rates, especially for very fine mineral particles.〔 It produces high concentrate grades from fast floating liberated particles 〔K E Barns, P J Colbert and P D Munro, "Designing the optimal flotation circuit – the Prominent Hill case," in: ''Tenth Mill Operators' Conference, Adelaide, South Australia, 12–14 October 2009'' (The Australasian Institute of Mining and Metallurgy: Melbourne, 2009), 173–182.〕 and is able to do this from a single stage of flotation.〔 The high carrying capacity of the Jameson Cell is particularly beneficial when high yields (mass pulls) are required, such as in recleaning in metals flotation and in the flotation of metallurgical coal, where yields can exceed 80%.〔R Araya, L Huynh, M Young and K Arburo, "Solving challenges in copper cleaning circuits with the Jameson Cell," to be presented at: Procemin 2013,Santiago, Chile, 15–18 October 2013.〕 The Cell was initially developed as a lower-cost alternative to conventional column flotation cells for recovering fine particles, and was first used in the Mount Isa lead–zinc concentrator in 1988.〔D Readett and B Clayton, "Cleaning hydrometallurgical liquor using Jameson Cells," in: ''Flotation Plants – Are They Optimized?'' Ed. Deepak Malhotra (Society of Mining, Metallurgy and Exploration: Littleton, Colorado, 1993), 164–170. ISBN 0-87335-124-X.〕 Since then, use of the technology has spread to include coal flotation, base and precious metal flotation, potash flotation, oil sands flotation, molybdenum flotation, graphite flotation and cleaning solvent extraction liquors.〔Xstrata Technology, ("Jameson Cell installations," ) Accessed 29 May 2013.〕 Xstrata Technology, Glencore Xstrata's technology marketing arm, listed 328 Jameson Cell installations in May 2013.〔 Cells have been installed by 94 companies in 27 countries.〔 Today, the technology is the standard in the Australian Coal Industry〔B A Firth, "Australian coal flotation practice," in: ''Advances in Flotation Technology'' (The Society of Mining, Metallurgy and Exploration: Littelton, Colorado, 1999), 289–307. ISBN 0-87335-184-3.〕 where well over one hundred Cells have been installed to recover coal fines.〔Xstrata Technology, ("Jameson Cell Applications." ) Accessed 1 July 2013.〕〔D Osborne, L Huynh, I Kohli, M Young and F Mercuri, "Two decades of Jameson Cell installations in coal," to be presented at ''The 17th International Coal Preparation Congress, Istanbul, 1–6 October 2013''.〕 It is mainly used in metals applications to solve final grade and capacity issues from conventional cell cleaner circuits.〔 It has found a niche in transforming traditional circuit designs where its inclusion allows cleaner circuits to be designed with fewer cells in a smaller footprint, while achieving cleaner and/or higher grade concentrates.〔 It has also made possible the recovery of previously discarded fine materials, such as coal〔R Q Honaker, A Patwardhan, M K Mohanty and K U Bhaskar, "Fine coal cleaning using Jameson Cells: the North American experience," in: ''Advances in Flotation Technology'' (The Society of Mining, Metallurgy and Exploration: Littelton, Colorado, 1999), 331–341. ISBN 0-87335-184-3.〕 and phosphate fines,〔A J Teague and M C Lollback, "The beneficiation of ultrafine phosphate," ''Minerals Engineering'', 27–28, (2012), 52–59.〕 thereby increasing the efficiency and extending the life of the world's non-renewable natural resources. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Jameson cell」の詳細全文を読む スポンサード リンク
