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.
