Tailing Disposal

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 18 t/m 3 due to their low G s while for metalliferous tailings the dry density is up to 15 t/m 3 due to their higher G s Figures 24 a and b show typical wet and dry density and w profiles with depth for...
