Moisture-Retaining Properties of Rocks in Ascending Capillary Leaching

详细

The moisture-retaining properties of rocks in the rock mass are considered at ascending capillary leaching. The dependences of the moisture capacity of disperse material of flotation tailings at ascending motion of solutions are found. The dependence of 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 water solutions to the rock mass is revealed. Based on a laboratory experiment, the specific parameters of capillary ascending filtration for the tailing dump are calculated with regard to moisture-capacity properties of the rock mass.
