After settling and selfweight 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 t/m 3 due to their low G s, while for metalliferous tailings the dry density is up to t/m 3 due to their higher G s. Figures (a) and (b) show typical wet and dry density and w profiles with depth for ...
