摘　　要：在绿色可持续化学发展要求下,探讨了在饲料磷酸盐生产过程中,磷矿中磷、钙、氟、硅等主要元素资源的全利用、无机酸的循环利用及耦合工艺利用,包括磷石膏中的硫资源循环利用;磷石膏中钙资源生产建筑胶凝材料的工艺;磷矿中钙资源作为磷酸钙盐产品的钙资源的工艺;湿法磷酸生产中磷矿的氟资源回收工艺;高硅磷矿生产低硅磷石膏的湿法磷酸生产工艺等绿色可持续的饲料磷酸盐生产技术.Under the requirement of green sustainable chemical development， the novel technologies for full utilization of phosphate rock were discussed， containing the utilization of main elements resources （phosphorus， calcium， fluorine and silicon， etc.）， the recycling of inorganic acid and the adopting coupling process in feed phosphate production. The cyclic utilization of sulfur resources in phosphogypsum， the building cementitious materials produced by calcium in phosphogypsum replacing primary limestone ore， the full utilization of calcium resources in phosphate rock as raw material of feed calcium phosphate product to reduce the consumption of limestone and lime， the whole process recovery technology of fluorine resources in phosphate rock by wet-process phosphoric acid production， the wet-process phosphoric acid technology to produce low silicon phosphogypsum by high silicon phosphate rock and the green sustainable feed phosphate production technologies were investigated in this study.
