smelting, in metallurgy, any process of melting or fusion, especially to extract a metal from its ore. Smelting processes vary in detail depending on the nature of the ore and the metal involved, but they are typified in the use of the blast furnace blast furnace, structure used chiefly in smelting. The principle involved in this means of extracting metals is that of the reduction of the ores by the action of carbon monoxide, i.e., the removal of oxygen from the metal oxide in order to obtain the metal.

smelting

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.

smelting [′smelt·iŋ]

(metallurgy)

The heating of ore mixtures accompanied by a chemical change resulting in liquid metal.

Smelting

the process of converting ores, usually metal ores, in smelting furnaces to produce a final product in molten form. Blast-furnace smelting is used in metallurgy for extracting metals from ores. Solid or molten metallic charges are converted by smelting in open-hearth furnaces, electric furnaces, and oxygen-Bessemer furnaces. Ferrous alloys and nonferrous metals are refined by smelting. Other applications of smelting are the production of alloys and the fusion of solid metals for pouring into cast ingots or for making intricate castings. A single cycle of the smelting process, as well as the resulting product is sometimes referred to as a smelt.
