摘　　要：讨论了磷矿浸取过程中各个因素对脱氟的影响。通过调整工艺参数和采用特殊的反应方式,在磷酸浸取磷矿的过程中控制氟向液相的转移,从而实现与反应同步除氟,生成高质量的湿法磷酸,该磷酸可直接用于生产饲料级磷酸氢钙。The influences of main factors on removing fluorine in the process of leaching phosphate ore were discussed. The removing of fluorine and the reaction of leaching phosphate ore with phosphoric acid could be conducted simultaneously by adjusting process parameters and using special reaction style to control moving of fluorine towards liquid phase in the process of phosphoric acid leaching phosphate ore. Wet proess phosphoric acid with high quality was obtained, it could be used directly to prodtuce feed grade calcium hydrogen phosphate.
