| Abstract: | The filtration rate and eutectic phosphorus loss greatly depend on the characteristics of the phosphogypsum crystallization in WPA production. Some surfactants added in extraction process can change the phosphogypsum crystallization and increase the reaction efficiencies. The domestic and international research achievements are reviewed. The mechanism of the surfactant effects on the phosphogypsum crystallization is briefly explained, and the problems and prospects are pointed out. |
