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.

Direct sulfide electrolysis extracts metal using less energy

Ores of metals including antimony, copper, nickel, and zinc are often compounds of sulfur. The metals are conventionally extracted by converting the ore into oxides by roasting at high temperatures, during which carbon and sulfur dioxide are emitted. The oxides are then converted to metals by heating them at temperatures over 1000°C.
