Smelting is a process of applying heat to ore in order to extract a base metalIt is a form of extractive metallurgyIt is used to extract many metals from their ores, including silver, iron, copper, and other base metalsSmelting 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.

Normally, the ampacity rating of a conductor is a circuit design limit never to be intentionally exceeded, but there is an application where ampacity exceedance is expected: in the case of fus What is a Fuse? A fuse is an electrical safety device built around a conductive strip that is designed to melt and separate in the event of excessive current.
