ABSTRACT:
An improved method in concentrating oxide ores by froth flotation process which comprises subjecting a sufficiently fine sized ore of a metal which can change the valency state from higher to lower by the action of inorganic reducing compounds in the presence of an effective amount of dihydroxyoleic acid collector-frother; the indicated compounds provide selectivity and/or recovery of oxide minerals of iron, manganese, tin, titanium, vanadium, and wolfram, over silica and silicate gangue.
