ABSTRACT:
A phosphate ore flotation process for subjecting a phosphate ore containing dolomitic impurities to beneficiation as follows: The flotation feed is first conditioned with fatty acid and fuel oil as collectors and then reconditioned with humic acid as a modifier; subjecting the reconditioned flotation feed to rougher phosphate flotation to collect the rougher phosphate concentrate from the overflow; subjecting said rougher phosphate concentrate to at least one cleaner phosphate flotation; and recovering the phosphate product in the overflow from said cleaner phosphate flotation step.
