江西贵溪化肥厂与某高校合作 ,成功开发出两步法由磷石膏制取硫酸钾新工艺 ,已通过省科委组织的专家鉴定。在已经完成小试的基础上 ,1月兴建 50 0 0ｔ/ａ硫酸钾中试装置。中试成功后 ,将投资近 3 0 0 0万元兴建年产 5万ｔ硫酸钾生产装置。此项目已被列入国家高技术产业化推进项 Guixi Chemical Fertilizer Plant in Jiangxi Province and a university cooperation, successfully developed a two-step process of potassium sulfate from phosphogypsum new technology has been identified by the Provincial Science and Technology Commission organized experts. On the basis of the completion of the pilot project, a trial of 500t / a potassium sulphate pilot plant will be set up in January. After the pilot success, it will invest nearly 30 million yuan to build an annual output of 50,000 t potassium sulfate production plant. This project has been included in the national high-tech industrialization promotion
