The results of DLVO theoretical calculations indicate that the total acting energy between the titanaugite and ilmenite particles at pH 5.9 is negative, showing as attraction, which causes the superfine titanaugite particles attach on the surface of ilmenite. At pH 8.5, because of large electrostatic repulsion energy, the total acting energy shows as strong repulsion, thus the superfine titanaugite particles can not attach on the surface of ilmenite.
