ABSTRACT:
In a process for beneficiating one or more mineral values of sulfide ores by treating the sulfide ore with a metal containing compound 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 separation between the values and gangue, the improvement comprising pretreating the sulfide ore by heating it to a temperature of at least about 80.degree. C. for at least about 0.1 hours.
