Stability Analysis and Stabilization of Miduk Heap Leaching Structure, Iran
To construct copper heap leaching structures, a stepped heap of ore is placed over an isolated sloping surface and then washed with sulphuric acid. The isolated bed of such a heap consists of some natural and geosynthetic layers. Shear strength parameters between these layers are low, so they form the possible sliding surfaces of the heaps. Economic and environmental considerations call for stu...
متن کاملInvestigative study into the hydrodynamics of heap leaching processes
Three mathematical models (mixed side-pore and profile side-pore diffusion with uniform or distributed pore length) are derived in dimensionless form to simulate the transport of solutes through the flowing channels and the stagnant pores of an unsaturated heap. Model parameters are determined from experimental tracer residence time distributions using the least square minimization approach. It...
متن کاملModelling solute leaching during fingered flow by integrating and expanding various theoretical and empirical concepts
Wetting front instability (fingered flow) accelerates solute transport through the unsaturated zone to the groundwater table. Whether fingers widen or dissipate close to the groundwater is unclear. Water flow in a two-dimensional artificial capillary fringe below a dry layer exhibiting fingered flow was investigated. The flow diverged strongly in the wet soil, suggesting that fingers dissipate....

متن کاملNumerical Experiments on Solute Transport in Ground- water Flow System
This paper proposes groundwater flow simulation models based on explicit finite difference method (FDFLOW) and Galerkin finite element method (FEFLOW) and solute transport simulation models based on Galerkin finite element method (FESOLUTE), random walk method (RWSOLUTE) and modified method of characteristic (MMOCSOLUTE). These coupled flow and transport models are aimed at simulation of solute...
