Smelting - Wikipedia

Smelting is a process of applying heat to ore in order to extract out a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

Why is copper extracted out of its ore using electrolysis ...

In the case of copper the changes in property make it much less effective in electrical components. Producing the copper via electrolysis produces copper that is almost completely pure. It is more expensive than using carbon reduction but less expensive than carbon reduction followed by cleaning it up to the required level of purity.
