ABSTRACT:
An improved method in concentration of oxide ores by froth flotation process which comprises subjecting a sufficiently fine sized ore of a metal which can change the valency state from lower to higher by the action of inorganic oxidizing compounds in the presence of an effective amount of a polyhydroxy fatty acid collector-frother; the indicated compounds provide selectivity and/or recovery of oxide minerals of iron, chromium, cerium, antimony, arsenic, titanium, zirconium, thorium, vanadium, niobium, tantalum, and wolfram, over silica and silicate gangue.
