Phase equilibrium of ternary system K2O–Al2O3–H2O is the key in realizing seeded precipitation process aluminum hydroxide product from alkaline leaching solution alunite tailings metallurgical industry. However, little work has been carried out about solubility system, especially for concentrated alkali region. The corresponding phase equilibria at 323.15, 333.15, 343.15, and 353.15 K were researched by using isothermal dissolution method Pitzer ion-interaction model. calculated Al2O3·3H2O...
