| Abstract: | producing cement retarder has become one of the important solutions for phosphogypsum comprehensive utilization. The disadvantageous effects of different impurities in phosphogypsum on the cement retarder are analyzed. Several process techniques and effectiveness for phosphogypsum purification including physical water scrubbing, chemical pretreatment and drying-calcination method are introduced. It is recommended that different purification process should be combined to different impurities content. |
