Abstract
A process for the recovery of copper from its ores by conventional procedures requiring heat in which the source of heat is microwave energy. The microwave energy is used to selectively heat the copper 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.
Claims14
A process for the recovery of copper from its sulfide and oxidic ores which comprises subjecting the ores to microwave energy under conditions to convert the sulfidic and oxidic compounds in the ores to compounds from which copper is more readily recoverable.
