The best molar ratio of NaOl to SPA for ilmenite flotation was 3:1, in which a 97.48% practical flotation recovery could be achieved. It is obviously larger than the calculated flotation recovery (84.36%). It is interesting to notice that the combined usage of collectors in ilmenite flotation has significantly reduced the collector dosage.
