Volume fraction of tailing sand under different head differences.

(a)

Particle size (μm)	1	2	3	4	5	6	7	8	9
Volume fraction
Original sample (%)	2.9	6.3	9.1	11.7	13.9	16.0	17.9	19.6	21.2
First substage (%)	3.4	7.1	10.2	13.1	15.6	17.9	20.0	22.0	23.6
Second substage (%)	3.4	7.2	10.5	13.4	16.0	18.4	20.5	22.4	24.2
Third substage (%)	3.1	6.7	9.6	12.3	14.7	16.9	18.9	20.8	22.5

Note: the compressed stage is divided into the first substage, second substage, and third substage.
