smelting | Definition & Facts | Britannica.com

Smelting, process by which a metal is obtained, either as the element or as a simple compound, from its ore by heating beyond the melting point, ordinarily in the presence of oxidizing agents, such as air, or reducing agents, such as coke.The first metal to be smelted in the ancient Middle East was probably copper (by 5000 bce), followed by tin, lead, and silver.

Types of Extraction | S-cool, the revision website

Methods of extraction Many metals are found in the Earth's crust as ores. An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more difficult it is to ...
