UFeO₄ was prepared by the reaction of magnetite with U₃O₈ and its solid state was characterlized by XRD. The sample was added to solutions in the atmosphere for the static leaching test. Finally, thermodynamic simulation of apparent solubility was performed on the basis of the dissolution behavior.
