Abstract
The moisture-retaining properties of rocks in the massif are considered at ascending capillary leaching. The dependences of the moisture capacity of disperse material of flotation concentration tailings at ascending motion of solutions are found. The dependence of the specific moisture capacity and specific moisture-yielding ability of finely dispersed material at water, pH-neutral and capillary filtration on the grain size and level of feeding aqueous solutions to the massif is revealed. Based on a laboratory experiment, the specific parameters of capillary ascending filtration for the tailing pond are calculated with regard to moisture-capacity properties of the massif.
