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 t/m 3 due to their low G s while for metalliferous tailings the dry density is up to 1.5 t/m 3 due to their higher G s.
