| 摘 要： | 对脲硫酸分解磷矿过程中酸解剂配比(即尿素加入量)、反应温度、磷矿粉细度、搅拌强度等对磷矿转化率和气相氟逸出率的影响进行了．探讨。实验结果表明．酸解剂配比是影响氟逸出率的最主要因素，由于尿素的加入．可使氟逸出率降低75％以上。

| Abstract: | Experiments were done on the emission of fluorine in the process of urea sulfuric acid decomposing phosphate rock. It was indicated that the composition of acidulation agent, reaction temperature, size of phosphate rock and stirring speed have effects on fluorine emission, in which composition of acidulating agent has the most extraordinary effect. With the feeding of urea, fluorine emission rate could be reduced by 75% in comparison with the traditional superphosphate production. |
