磷酸中铁铝镁杂质对开阳磷矿分解速率的影响
The Effects of Fe，Al and Mg Impurities in Phosphoric Acid on Reacting Kinetic of KaiYang Apatite Ore
摘要
Abstract
The effects of Fe,Al and Mg impunities on the reaction process of the digestion of Kaiyang phosphate rock by phosphoric acid was studied.According to the variation of H ion activity and the microphenomenon of the process,it was found that the reaction rate decreases when the solid phases,which was produced during the reaction process,cover the reactive points on the surface of ore paticles,and plug the pores that are used for mass transfer.关键词
