Discussion the degradation of available P_2O_5 of SSP maked from phosphate rock with high iron and aluminum content

介绍了高铁铝磷矿制过磷酸钙有效磷退化的情况,分析了有效磷退化的机理;通过提高矿粉细度,提高硫酸用量,合理搭配矿源,降低熟化温度,可改善和防止有效磷退化的现象。

Introduction the degradation of available P2 05 of SSP maked from phosphate rock with high iron and aluminum content. Analysis the degradation of available P2O5. It can improve and prevent the degradation of available P2O5 by increasing phosphate rock degree of fineness and raising the amount of sulfuric acid,with a reasonable source of phosphate rock and reduction of touring temperation.
