Abstract
A method is shown for capping a tailings pond of the type which receives fines-containing aqueous effluent from an industrial process. A mineral formulation is prepared by mixing together lime, a pozzolanic component, a sulfate component and water. The mineral formulation is applied to the surface of the fines-containing tailings pond and is allowed to harden to form a surface coating on the tailings pond.
