May 13, 2015· Underground mine backfilling is a form of ground improvement that has to be carried out in the mine sites. The backfilling provides ground support and regional stability, thus facilitating ore removal from nearby regions. The large underground voids created by the ore removal are backfilled with the waste tailings in the form of paste fills, hydraulic fills, and others. The tailings are placed ...
Mar 01, 2009· The hydraulic performance was judged in terms of ability of device in processing discharge for given head losses. The results of the experiments show that the hydraulic performance of the modified hydrocyclone is better for entire headloss range under study ().For the given flow rate, the headloss in the modified hydrocyclone relative to the Standard and gMax cyclone is less by 30% and …
The working principle of Xinhai hydrocyclone is centrifugal sedimentation, when two phases (or three phases) mixed liquid is fed into hydrocyclone by a certain pressure liquid and produces strong three-dimensional-elliptic rotational movement. Due to the different density of particles, the centrifugal force, the centripetal buoyancy and drag force is different.

Hydraulic sandfill is prepared by dewatering the mill tailings stream to a pulp density of approximately 65-70% solids (depending on S.G) and then passing it through hydrocyclones to remove the "slimes" and retain the sand fraction for backfill. Slimes are removed to improve the percolation rate of the backfill.
