ABSTRACT:
One or more mineral values of sulfide ores are beneficiated by cotreating the sulfide ore with a metal containing compound and a reducing gas under conditions such as to selectively enhance the magnetic susceptibility of the mineral values to the exclusion of the gangue in order to permit a physical separation between the values and gangue.
