After settling and self-weight consolidation, the dry density of the undesiccated tailings is a function of the G s of the tailings solids. For coal tailings, the dry density is about 1.8 tm 3 due to their low G s, while for metalliferous tailings the dry density is up to 1.5 tm 3 due to their higher G s. Figures 2.4a and b show typical wet and dry density and w profiles with depth for ...
