A method of extracting metal from an underground ore body. The body is heated by electric induction to a temperature sufficient to break up the metallic ore compound and liquefy the metal. The metal flows into production wells where it is collected and transported to the surface, as by rapid solidification into powder or pellets in a pressurized gas stream. The electric induction is conveniently effected by passing alternating current through a conductor encompassing that portion of the ore body to be heated.
