摘　　要：介绍浏阳中品位磷矿原矿Ⅱ及选矿Ⅰ、Ⅱ采用"料浆浓缩"工艺制取磷酸一铵的评价实验。对湿法磷酸工艺、磷酸氨化、磷铵料浆浓缩和干燥等过程进行了研究,测定了有关的物性数据和技术经济指标,为其采用料浆浓缩法制磷酸一铵工艺的可行性和设计提供了参考数据。The lab. experiments of MAP manufacture with ASCP from Liuyang medium grade crude phosphate rock Ⅱ and concentrated phosphate rock Ⅰ,Ⅱ are described. The technologies of wet-process phosphoric acid （WPA）, ammoniation of WPA, concentration of ammoniating slurry and its drying as well as their physic-chemistry data, tech-economical indexes are studied, which provide the references of feasibility and design for MAP manufacture with ASCP from medium grade phosphate rock in China.
