Abstract
Multimode and single mode microwave energy is used to improve the extraction of metals from chalcogenide minerals. In one process microwave energy is used to comminute the mineral after which the mineral is reacted with acid in the presence of microwave energy. Following treatment the mineral is removed and the extracted metal is recovered from the acid. In another process chalcogenide minerals are exposed to the magnetic field maximum or the electrical field maximum of a single mode electromagnetic energy. This treatment causes a phase separation between metals and silicates within the mineral leaving metal rich regions from which the metal can be readily recovered by traditional methods.
