Mass Transfer in Upward Percolation of Water Solutions in Tailings

The article describes the experiment on the upward percolating mass transfer by water solution according to the natural mechanism of movement of solutions toward ground surface with water evaporation in atmosphere. Useful components settle out from the solutions and concentrate on the evaporation barrier. The experiment simulates a complete cycle of processes for flotation tailings of complex ore: feed of solutions in boreholes from surface to bottom of a tailings body; spreading of the solutions in the tailings body; capillary ascent to the surface; settling out and concentration of useful salts on the evaporation barrier. The usability of this approach and some parameters of the mass transfer process can be found from the relevant research.
