- Smelting is a process of extracting pure metals from their ores through heating and melting. It is an essential step in producing usable metals from raw ores extracted from mines. The end product of smelting is molten metal, which can then be refined into pure metal for use in making various products.

Jul 12, 2023 · Extractive metallurgy is the practice of removing valuable metals from an ore and refining the extracted raw metals into purer form. The field of extractive metallurgy encompasses many specialty sub-disciplines, including mineral processing, hydrometallurgy, pyrometallurgy, and electrometallurgy.
In hydrometallurgical smelting, metals are extracted from ores using water-based solutions and chemical reactions rather than heat. Leaching is a common hydrometallurgical process where ore is dissolved in a suitable aqueous solvent to separate metals.
Jan 9, 2018 · The process of separating a metal from its ore is known as smelting. Smelting is widely practiced today and has a long history dating back to the Bronze Age, when ancient peoples first learned the technique.
