ABSTRACT:
A tailings pond sludge layer of high density and strength is obtained by treating the sludge with an additive selected from a specific family of hydrolized starch additives which impart improved permeability and shear strength characteristics to the sludge. Thereafter, the sludge is mixed with sand which adds self-weight whereby further dewatering of the sludge sand mixture is accomplished. Unlike untreated sludges or sludges treated with other known additives or flocculants, sludge treated with the aforementioned hydrolyzed starch additives is able to support the sand.
