Abstract
A mathematical model for determining the concentration changes in solution during the dissolution of a uranium dioxide-pyrite mixture has been developed using a Fe2(SO4)3-H2SO4 lixiviant. When modeling such a leaching process, the two dissolution reactions are considered to be slow enough so that the reactions in solution can be assumed to be at continual equilibrium. This situation allows for the partial equilibrium approach to be utilized in modeling the overall leaching process.
