Abstract
A process for the recovery of molybdenum and rhenium from their sulfide ores which comprises subjecting the ores to microwave energy in the presence of oxygen to selectively heat the sulfides to convert them to oxides, and recovering the formed oxides. Alternatively, the sulfides in the ore are selectively heated with microwave energy in the presence of chlorine to convert them to the corresponding chlorides, and the metals recovered from the chlorides.
