Metallurgy - Wikipedia, the free encyclopedia Extractive metallurgy is the practice of separating metals from their ore, and refining them into a pure metal. Metallurgy is a domain of materials science and of materials engineering that studies the physical and chemical behavior of metallic elements, their intermetallic compounds and their mixtures, which are called alloys. Metallurgy is also applied to electrical and electronic materials where as metals such as aluminium, copper, tin and gold are used in power lines, wires, printed circuit boards and integrated circuits. en.wikipedia.org /wiki/Metallurgy   (884 words)

ProductCatalog?category=01-3414 This proceedings volume is a collection of 35 international papers focusing on issues in ferrous and non-ferrous processing, and innovations in injection metallurgy relating to intense smelting, bath smelting, converting, fuming, alloying, fluxing, and refining. This International symposium, organized by the G.K. Williams Cooperative Research Centre for Extractive Metallurgy, was co-sponsored by The Minerals, Metals and Materials Society (TMS) in the USA and The Iron and Steel Institute of Japan (ISU), and was held during 1-3 July, 1996 at the Melbourne Hilton on the Park in Melbourne, Austrailia.

Scientific Report 1992-1994 Actual research areas are the mathematical modelling of unit processes in extractive metallurgy and the assessment and calculation of phase diagrams, for which as a supporting tool a software library is developed for solution thermodynamic calculations. Selecting and solving the correct thermodynamic and kinetic equations is essential for the mathematical modelling of unit processes, such as the refining of (stainless) steels. Chemical thermodynamics creates the framework within which the basic principles of extractive metallurgy can be explained. sirius.mtm.kuleuven.ac.be /Research/Report94/Chapter5.html   (2440 words)

PMR: The Minting of Platinum Roubles More likely to be true is a brief note in a typewritten statement in the possession of Johnson Matthey, stating no more than “the specimens formed part of a consignment sent to Johnson Matthey for refining about 1870” ( 2). His main interests are the application of metallurgy and materials science to new areas of research as well as conventional applications in materials, catalysis, biomedical applications, and renewable energy systems including batteries and hydrogen storage. Rather than stop the transaction, they thought it a good idea as it would raise capital for them – at that time, the refining capacity of the young U.S.S.R. had been disrupted. www.platinummetalsreview.com /dynamic/article/summary/48-3-134-138   (326 words)

The Lime Cycle Lime serves as a flux for removing impurities ( silica, phosphorous, and sulphur) in refining steel. In non ferrous metallurgy, lime is used to beneficiate copper ore, make alumina and magnesium manufacture, extract uranium and recover gold, silver etc. The chemical industry requires lime to make such chemicals as sodium alkalies, calcium carbide, calcium hypochlorite, citric acid,petrochemicals etc. The paper industry uses lime as a causticizing agent and for bleaching. The quicklime and hydrated lime derived from Dolomite will contain magnesium as well as cacium compounds. www.limeindustries.com.au /thelime.htm   (4590 words)
