Abstract

When density of leaching solution and groundwater are different, gravity becomes an important factor that affects the hydrodynamics of in-situ leaching process. Therefore, the leaching solution flows in the porous medium noticeably at a lower rate than expected which might introduce difficulties for recovering the metal trapped in the upper part of the geological layers. This paper investigates this gravity effects on the flow regime by including it in the Darcy equations. Overall, the modeling consists of calculation of the pressure and density distribution and the filtration Darcy velocity with gravity effect, although leaching kinetics also impact on the density of the porous medium. The density of the porous medium in a couple parameter that affects the hydrodynamics of the leaching process. The full coupled differential equations are numerically solved using the CUDA (Compute Unified Device Architecture) parallel computing platform facilities provided by Nvidia. Results show that the pressure equation is solved by CUDA on graphics processing unit (GPU) an order of magnitude faster than on central processing unit (CPU).
