Abstract: Industrial test of anionic reverse floatation to northeastern a Hematite by using cyclonic-static micro-bubble flotation column was corried out.The result manifest that: under the circumstance of the grade of the row mine is 46.91%, got the grade of the concentrate is 68.17%, the grade of the gangue is 17.71%,and the recovery is 84.10% by the short flow of one rougher and two scavengers ,it is comparative to the  flotation machine system in the same period.The test shortens the structure of floatation process of hematite, and reduces the consumption of reagent.

Key words: Hematite, Flotation column, Short process, Anionic reverse floatation
