smelting

Определение smelting в Английский Язык Английский Язык словарь: The process of melting or fusion, especially to extract a metal from its ore; Process by which a metal is obtained from its ore, either as the element or as a simple compound, usually by heating beyond the melting point, ordinarily in the presence of reducing agents such as coke or oxidizing agents such as air (see oxidation-reduction). A metal whose ore is an oxygen compound (e.g., iron, zinc, or lead oxide) is heated (reduction smelting) in a blast furnace to a high temperature; the oxide combines with the carbon in the coke, escaping as carbon monoxide or carbon dioxide. Other impurities are removed by adding flux, with which they combine to form slag. If the ore is a sulfide mineral (e.g., copper, nickel, lead, or cobalt), air or oxygen is blasted through (matte smelting) to oxidize the sulfide to sulfur dioxide and any iron to oxide slag, leaving the metal. See also metallurgy; mineral processing; The extraction of metal from its ore by heating; the process of high temperature heating of metallic ores in order to melt and separate the pure metal from associated impurities; The process of extracting a metal from its ores by heating; the chemical reduction of the oxide of the metal with carbon in a furnace Earth and other impurities, separating as lighter and more fusible slags, can readily be removed from the reduced metal; from Smelt; a metallurgical process that involves reducing metal ions to the free metal; A process in which a metal oxide (such as PbO, ZnO, or Fe2O3) is reduced to the corresponding metal; Process where a metal is separated from the other materials in an ore mineral; Fusion or melting process in order to separate metals; The process of melting ore in order to release the desired minerals from their gangue; The high-temperature process by which pure metal is produced from an ore; The process of extracting crude metal from its ore or concentrate by fusion, before being sent to the refinery for final processing; Melting scrap for a crude separation of precious metals from impurities, generally in preparation for refining; Process of producing molten aluminium by the reduction of alumina

smelt: To smelt a substance containing metal means to process it by heating it until it melts, so that the metal is extracted and changed chemically. Darby was looking for a way to improve iron when he hit upon the idea of smelting it with coke instead of charcoal. To melt or fuse. Used of ores. Any of various small silvery marine and freshwater food fishes of the family Osmeridae, found in cold waters of the Northern Hemisphere, especially Osmerus mordax of North America and O. eperlanus of Europe. A past tense and a past participle of smell. a past tense and past participle of smell. to melt a rock that contains metal in order to remove the metal. Any of certain slender, silvery, carnivorous, food fishes (family Osmeridae) having a small fleshy (Finans) Smelts live in cold northern seas, and most species spawn a short distance upstream. The American smelt (Osmerus mordax), introduced from the Atlantic to the Great Lakes, is the largest smelt, about 15 in. (38 cm) long. The European smelt (O. eperlanus) is similar. Among Pacific species are the rainbow herring, capelin, and eulachon, or candlefish, which is so oily at spawning time that it can be dried and burned as a candle. Silversides (see grunion) and other unrelated fishes are sometimes called smelts
