Simulation of an Ionic Rare Earth Leaching Process Based on the Darcy Law-Chemical Reaction Engineering-Transfer of Dilute Substance Coupling

The basic principle of in situ leaching is chemical mining. process to inject solution into the ore body, and spread pores mountain. completed by coupling action liquid seepage field ion exchange reactions. In production process, only one injection can be carried out a certain stope, so it impossible improve effect through practice. By simulating rare earth ions, this paper builds test stope true three-dimensional numerical model simulates under control, exchange, dilute material transfer porous media. migration rule RE3+ Mg2+ stopes was analyzed evaluate effect. It great significance increase recovery rate ore.
