The saturated area is an important subject in the field of heap leaching. Based on the review of researching on heap leaching at home and abroad, the saturated surface of heap leaching is researched deeply and thoroughly for the first time in nonlinear dynamics. The purpose of this work is to reveal evolvement mechanism of the saturated surface and bring forward a technique antitype to control saturated area.The influence rule of the saturated surface and the relation of the saturated surface and leaching r...
