Abstract

Abstract

Governing equations for a fully coupled Flowing-Reaction-Deformation behavior with Mass Transfer in heap leaching process were developed.These equations were solved using an explicit finite different method under the conditions of invarable application rate and constant hydraulic head.The distributions of the degree of the saturation as well as the distributions of the concentration of the reagent and the solute was given.A cubic relationship between the mineral recovery and the leaching duration is obtained based on the numerical results.The relationship can be used to predict the recovery percentage of the valuable metal.
