Abstract A process for the recovery of copper, molybdenum and rhenium-from their ores by conventional procedures requiring heat in which the source of heat is microwave energy. The microwave energy is used to selectively heat the metal compounds, such as sulfidic and oxidic compounds, in the ore, as respects the gangue, to convert the compounds into other compounds, such as oxides and chlorides, from which copper is more readily recoverable.
