ABSTRACT:
In a process for beneficiating one or more mineral values of sulfide ores and/or metal oxide ores selected from the group consisting of bauxite, taconite, apatite, titanium oxides and the metal oxides of Groups IIIB, IVB, VB, VIB, VIIB, VIIIB, IB, IIB and IVA by treating the 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 removing at least a portion of any elemental sulfur present from the ore prior to the treatment with a metal containing compound.
