Abstract:
A process of dewatering tailings is provided comprising mixing the tailings with a sufficient amount of an additive or a mixture thereof; depositing the resulting mixture into a disposal area; pumping water from the deposit to one or more sumps, and allowing the deposit to reach a sufficient strength; and removing remaining deposit water and rainfall through one or more of a network of ditches, a decant tower, or a plurality of dike drainage structures to yield a non-segregating deposit for reclamation.
