A Mathematical Model for Isothermal Heap and Column Leaching
Leaching occurs in metals recovery, in contaminated soil washing, and in many natural processes, such as fertilizer dissolution and rock weathering. This paper presents a model developed to simulate the transient evolution of the dissolved chemical species in the heap and column isothermal leaching processes. In this model, the solid bed is numerically divided into plane layers; the recovery of...
متن کاملA New Analytical Solution for Determination of Acceptable Overall settlement of Heap Leaching Structures Foundation
There are some artificial and natural materials on foundation of heap leaching structures. Geomembrane liner is the most important artificial isolated layer of these structures. The thickness of this layer is about 1 to 2 mm. Foundation overall settlement of such structures changes the primary length of the geomembrane layer. If the strain of geomembrane is more than allowable one, the layer wi...
متن کاملStability 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 کاملMathematical Model for Distributed Heap Memory Load Balancing
In this paper, we will introduce a new method to achieve the fair distribution of data among distributed memories in a distributed system. Some processes consume larger amount of heap spaces [1] in its local memory than the others. So, those processes may use the virtual memory and may cause the thrashing problem [2].At the same time, the rest of heap memories in that distributed system remain ...
متن کاملA Mathematical Model for Flood Protection
Many regions in the world are protected against flooding by a dike, which may be either natural or artificial. We deal with a model for finding the optimal heights of such a dike in the future. It minimizes the sum of the investments costs for upgrading the dike in the future and the expected costs due to flooding. The model is highly nonlinear, nonconvex, and infinite-dimensional. Despite this...
