Clogging of the pores of the porous medium occurs in different processes such as geothermal injection pumps, hydrocarbon wells, and underground water extraction wells. We need a model that can simulate these blockages in order to predict how fundamental variables of the porous medium change under different flow regimes and different particle sizes in the fluid (for example, the relationship between porosity and permeability changes). The aim is to simulate clogging in a porous medium using a pore network model. Simulations should model pore clogging and show how the permeability of the sample changes due to pore clogging. In the pore network, there are often thousands (or millions) of pores... 

Due to humanity's increasing demands, the provision of raw materials plays a crucial role in meeting these needs, with a significant portion of the required materials being obtained from mines. One method for increasing the efficiency of mine wastes is heap leaching. A leaching heap is a layered mound of low-grade ore particles piled on an impermeable layer called a leaching pad. After being sprayed on the heap and reacting with the ores, the leaching solution is drained through the drainage system located in the heap leach pad and transferred to the collection pond for recovery of the target minerals. Due to the flow of fluid within the heap and the degradation of particles due to leaching,...
