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.
