胶磷矿生产磷酸的研究

对胺磷矿的组成和性质，胺磷矿的反应活性、发泡及消泡性能，湿法磷酸制备及磷酸的浓缩和澄清进行了试验研究。结果表明：用大峪口胺磷矿作原料，可生产出浓度为50％～51％P2O5的磷酸，符合生产高效磷肥的要求。

Study on preparating phosphoric acid by phosphate rock

The composition. properties, reaction activity, capacity of frothing and defrothing of phosphate rock and the preparation, thickening and clarification of wet phosphoric acid are stutiied. The results show that phosphoric acid with 50%-51% P2O5, which can meet the requirement of preducing high effective phosphate fertilizer, can be prcparated by Dayukou phosphate rock.
