COMPOSITION AND PROCESS FOR INCREASING THE SHEAR STRENGTH OF PROCESSING WASTES USED FOR TIP BUILDING AND UNDERGROUND CONSOLIDATION

摘要

COMPOSITION AND PROCESS FOR INCREASING THE SHEAR STRENGTH OF PROCESSING WASTES USED FOR TIP BUILDING AND UNDERGROUND CONSOLIDATION There are provided compositions and processes for enhancing the initial and long term shear strength and initial tip stability of process wastes. The process wastes are aqueous dispersions such as the slurry tailings from mining operations. The compositions are comprised of the process waste, cement and a water absorbent polymer which is a mixture of Mannich acrylamide polymers and dimethyldiallyammonium halide polymers.
