Compositions and methods for increasing the shear strength of process wastes used to build up heap and consolidate subsoil

摘要

Compositions for enhancing the initial and long term shear strength and initial tip stability of process wastes, which are aqueous dispersions such as the slurry tailings from mining operations, are comprised of the process waste, cement and a water absorbent polymer which is a mixture of a Mannich acrylamide polymer and a dimethyldiallyammonium halide polymer.
