Anisotropic percolatory-convective diffusion in underground leaching

Creators

Description

The two-dimensional problem of the propagation of an impurity in underground flows is investigated with allowance for chemical reactions between the solvent and the ore-bearing matrix material. The flow velocity field generated by a pair of wells (source-sink) is assumed to be steady and known. A numerical method of solving the system of equations of convective diffusion and nonequilibrium sorption is discussed. Typical isoconcentration fields are presented. The effect of the influence parameters on the principal characteristics of the leaching process is analyzed
