Fine particle percolation dynamics in porous media

Physical Review Research
The influences of restitution coefficient, e_{n}, interparticle friction, μ, and size ratio, R, on gravity-driven percolation of fine particles through static beds of larger particles in the free-sifting regime (R≳6.5) remain largely unexplored. Here, we

Some solutions to the problems in fine particle flotation

, 2005
The difficulty in fine particle flotation has been attributed, among other things, to a low bubble-particle collision efficiency. Many technologies have been developed which aim at increasing bubble-particle collision efficiency, either by generating ...
