The lead sulphide mineral galena, also called lead glance, whilst an important ore of both lead and silver, is also a natural semiconductor. That is to say, it has an electrical conductivity value falling between that of a conductor, such as metallic copper, and an insulator, such as glass. In certain circumstances galena will conduct electricity.
