摘要
揭示了磷石膏作为硫钙资源所蕴含的价值,回顾磷石膏制硫酸联产水泥的技术发展历程,分析目前所面临的技术难题与经济影响因素。采用创新技术确保原料总磷w(P2O5)始终低于0.6%,可使磷石膏制硫酸联产水泥的技术经济性产生一个大的飞跃。
The values of phosphogypsum as a resource of both sulphur and calcium are disclosed. The technical development histo ry of co-production of sulphurie acid and cement with phosphogypsum is reviewed. Technical difficulties faced today and economic factors are analyzed. An innovative technology proposed can ensure total w（ P2O5 ） of feedstock phosphogypsum consistently below 0. 6%, realizing a giant leap in technical economics.
