| Abstract: | Analyzed the present status of traditional cyclonic microbubble flotation column, influence of flotation feed property and conditions, especially feed concentration to flotation colomn performance were elaborated. Utilization of pre - flotation cyclonic microbubble flotation column to slove the flotation of fine coal with high concentration was proposed. And the feasibility of this method was experimentally testified, which is of guidance significance for flotation in industrial field. |
