Selective Flocculation of Fine Grain Oolitic Hematite Behavior Research

Abstract:

The fine oolitic hematite ore (<20µm) is easily covered by the ore slime, therefore, it is processed very difficultly with traditional crafts, for example, gravity treatment, magnetic separation, and flotation. The tiny iron ore is unable to recycle effectively, bring about a large of useful minerals running off. It is indicated that the selective flocculation is effective separation craft in many research works. The good dispersion of fine particles is the selective flocculation essential condition, the excessive dispersion will destroy the selective flocculation, at the same time it can be influenced by the water quality, pH, the mixing time, the shear rate and the dispersing agent dosage. In this paper, to oolitic hematite ore, the chemistry dispersion research is conducted to provide the foundation for further selective flocculation separation.
