What does smelting mean?
Smelting is the high-temperature process of extracting metal from ore or another metal-bearing material. During the process, ore is heated in a furnace, often with a flux that helps separate the metal from unwanted minerals and impurities. The word is commonly used as a noun, as in iron smelting or the smelting of copper, and can also function as a present participle, as in a foundry that is smelting ore. Although people may use melting as a broader alternative, smelting has a more specific industrial meaning: it describes the recovery and separation of metal rather than simply the liquefaction of a material. Smelting has long been central to metallurgy and the development of metalworking. Its associations with furnaces, heat, and chemical transformation make it a useful term for discussions of mining, manufacturing, historical technology, and the environmental effects of metal production.
The process of extracting metal from ore by heating it to a high temperature, often with the aid of a flux.
"The smelting of lead and zinc ores was historically difficult because of their toxicity."
Usually used in technical, industrial, historical, or environmental contexts.
Present participle of smelt: to melt metal, especially to separate it from ore.
"The workers spent the night smelting iron in the furnace."
The form is commonly used in technical descriptions of mining and metalworking.
This is the standard plural form, although smelting is usually used in the singular.
"The archives contain records of several smeltings conducted at the site."
From stubborn ore to usable metal, smelting is where heat does the heavy lifting.

Where does smelting come from?
The word smelting is formed from smelt plus the suffix -ing. The verb smelt descends from Old English and is cognate with melt and with related forms in other Germanic languages, all associated with the idea of making a solid substance liquid by heat. Historically, smelting developed as the specialized name for the process of melting metal-bearing ores in a furnace.
