摘要

In the Florida phosphate industry, a two-stage flotation process is employed for the recovery of the phosphate mineral value. In both stages, conventional flotation cells are commonly used. In the present study, we have studied the effectiveness of column flotation in amine separation of silica from phosphate rougher concentrate. Pilot plant studies carried out in a 0.45 m x 1.2 m dual extraction flotation column (DEC) are presented and compared with plant performance employing conventional flotation cells on both fine and coarse amine feeds.
