However, final recovery of phosphate at appropriate dosage of reagent was insignificant. This could be ascribed to the increase of iron recovery to final concentrate likely due to collecting action of rhamnolipid for iron minerals. In coal flotation, the increase of rhamnolipid concentration in mixture with pine oil
