Uranium In Situ Leaching

Abstract The paper deals with simulation of in-situ uranium leaching technological process, collecting data for forecasting and leaching process control. It provides numerical simulation of uranium in-situ leaching (ISL) using Comsol Multiphysics software package application. Previous studies evaluated main hydrodynamic characteristics of wells and reservoirs, such as the coefficient of resistance and the saturation recovery; while this paper is concerned with determining the changes in process variables in the wells during operation.

Abstract Ukrainian uranium ore mining and milling facilities are located in the tight populated areas on the valuable agricultural lands of Ukraine. The almost 50th years’ activity of these enterprises has caused the radioactive contamination of the environment. The most dangerous facilities happened to be those ones which contaminate the entrails for a long time, namely: tailings which were discharged with the uranium ore uranium mill and former uranium in-situ leaching sites which are now decommissioned and left without relevant environmental protection measures. This paper considers two uranium facilities, which impact in a similar way on such an environmental entity as underground water: the tailings and in-situ leaching site located in Dnipropetrovsk region.

The Difference

In-Situ Leaching is a method of extracting minerals by selectively dissolving it with a leaching solution directly in the place of occurrence of the mineral. In practice, during the development of deposits with the In-Situ Leaching method, situations arise when the solution tends to go down below the active thickness of the stratum. This may be due to geological heterogeneity of the rock or gravitational sedimentation of the solution in the rock due to the difference in the densities of the solution and groundwater. As a result of the deposition of the solution along the height, there is a decrease in the recovery of the metal located in the upper part of the geological layers. This article examines the effect of gravity on the flow regime during the filtration of the solution in the rock. The influence of the gravitational effect on the flow of solution in the rock is studied for different ratios of the densities of the solution and groundwater without taking into account the interaction of the solution with the rock. The CUDA technology is used to improve the performance of calculations. The results show that the use of CUDA technology allows to increase the performance of calculations by 40-80 times compared to calculations on a central processing unit (CPU) for different computational grids.
