Acid-base potential scale was introduced to overcome the difficulties caused by acid-basic theory in the quantitative research on structure performance of flotation reagents, and to expand the scale of application of acid-basic theory. The selective criterion was presented, which is the function of acid-base potential scale and frontier molecular orbital energy level of flotation reagents. With this selective criterion, the structure performance of RA-315 as anion reverse flotation collector of hematite and sulphide mineral collector was studied. The conclusions are in accordance with the flotation test results, which indicates that acid-base potential scale plays a great promotion role in the quantitative research on structure-activity of flotation reagents.
