Smelting - Wikipedia

Smelting is a process of applying heat to ore in order to extract 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.

Does Silicon Conduct Electricity? - Reference

Follow Us: Silicon is typically a very poor conductor of electricity and often considered an insulator. However, a process called doping introduces a small amount of other material into the crystal structure to convert silicon from an insulator to a semiconductor. Semiconductors are essential parts of computers and other electronics.
