摘　　要：为探究胶磷矿中铝在不同条件下的溶出能力,采用不同体系对胶磷矿中的铝进行溶出实验。实验结果表明:氢氟酸对胶磷矿中铝的溶释性很强,最佳条件为氢氟酸用量8%、反应时间1 h、反应温度55℃、搅拌强度150 r/min,该条件下胶磷矿中铝的溶出率为95.7%。In order to explore the dissolution ability of aluminum in collophanite under different conditions, different systems are used to carry out the dissolution experiment of aluminum in collophanite. The experimental results show that hydrofluoric acid has a strong solubility for aluminum in collophanite, the optimal conditions are as follows: The amount of hydrofluoric acid is 8%, the reaction time is 1 h,the reaction temperature is 55 ℃, the stirring intensity is 150 r/min. Under these conditions, the dissolution rate of aluminum is 95.7%.
