高收率湿法磷酸制饲料级磷酸氢钙方法的研究

Research of Making Calcium Hydrophosphate with High Retracting Wet Phosphoric Acid

一种用湿法磷酸制饲料级磷酸氢钙的有效方法，将传统的二步法的Ｐ_２Ｏ_５收率从６０％～７０％提高到９０％以上。

This is an efficient method for making feed grade calcium hydrophosphate with wet phosphoric acid.It improves the retracting rate of 60￣70% P_2O_5 of traditional two-step method to that of more than 90%.
