摘要：由于高品位磷矿的日益贫乏,湿法磷酸中含有大量的杂质,导致生成大量继沉淀盐。继沉淀盐是湿法磷酸生产中遇到的主要难题,综述了不同浓度磷酸的继沉淀盐组成、性质及国内外关于继沉淀盐的不同防治方法。
Post precipitation is the major puzzle encountered in WPA production, resulted from the high content of impurities in WPA for the increasing shortage of high-grade phosphate rock.The composition and nature of post precipitation in WPA of different concentrations are reviewed, and the methods for post precipitation prevention and control both domestic and abroad are presented.
