This paper discusses the application of a reactive transport model as a powerful tool for the understanding of the hydrogeochemical processes that occur in one of the waste rock piles of the first uranium mine in Brazil, seeking to subsidize the appropriate choice of a remediation strategy. The Brazilian mine located at the Poços de Caldas plateau, in the state of Minas Gerais, generated approximately 27.2 × 106 m3 of waste rock. The waste rock pile object of this study presents a volume of 12.4 × 106 m3 and an area of 56.9 × 106 m2. Pyrite oxidation was found to be a critical factor in the mobilization of metals and radionuclides to environment. It was estimated that acid drainage generation will last for 600 years. The long time scale involved on the oxidation of pyrite materials implies the need for adoption of permanent remedial actions.
