Dry Density

If deposited tailings are always maintained under water the dry density achieved due to their self-weight is given by their G s and how rapidly the tailings are deposited (Williams 2014) If the rate of rise of the tailings is high the tailings may remain under-consolidated and the average dry density achieved may be as low as 0 5 t/m 3
