Experimental Study of the Negative Impact on the Environment During the Extraction of Uranium by In-Situ Leaching

The purpose of this study was a detailed analysis of all aspects related to the impact of objects and structures of the planned economic activity on the environment on the territory of the Semizbay deposit in the Republic of Kazakhstan. In the course of the work, the geoecological characteristics of the Semizbay deposit were presented. The analysis of data on the state of the components of the natural environment, based on the materials of earlier studies at the facility, was carried out. On the basis of the actual material, a list of priority pollutants subject to monitoring was compiled. The methodology and organization of the projected works are given. The types, conditions, scope of work were indicated. During the study, the following were carried out: soil sampling was carried out in the vicinity of the deposit, radiochemical analysis, and X-ray diffraction analysis. As a result of the study, a program of geoecological research was developed on the territory of the deposit: the content of radionuclides and the mineralogical composition of the sample were determined, which can become an alternative for further research on the territory of the enterprise.
