The process circuit and post-closure seepage chemistries for these alternatives could be affected by weathering processes within the tailings following placement. The geochemically dominant processes are sulfide oxidation and subsequent gangue mineral dissolution, with attendant solute release to tailings porewater. Predictions of the chemical compositions of tailings porewater and seepage during the mine’s operation and after closure is the focus of this document.
