Issues in the design of production strings of process wells for insitu uranium leaching

Известия высших учебных заведений: Геология и разведка
Background. Uranium mining by in-situ leaching (ISL) requires specialized methods for the construction and operation of process wells to ensure their reliable performance throughout the entire mining period of cells, blocks, and deposits.

Environmental Impacts of In Situ Leaching Uranium Mining: A Review

Environments
In situ leaching (ISL) is the most popular method for uranium mining worldwide, particularly in arid and semi-arid regions. Despite its economic benefits, ISL raises concerns about radioactive migration and groundwater contamination. This review assesses the environmental impacts of ISL uranium mining, focusing on radionuclide transport pathways and ...

Multiscale heterogeneity and water abundance of uranium aquifers in coal measures and its significance

Meitan xuebao
The Ordos basin is a crucial comprehensive energy base in China, where coal and sandstone-type uranium resources frequently coexist in an associated form within the same clastic aquifer system, characterized by a typical “coal below, uranium above ...

IMPROVING THE EFFICIENCY OF IN-SITU URANIUM LEACHING VIA OXYGEN-ENRICHED LIXIVIANT INJECTION

Rudarsko-geološko-naftni Zbornik
This paper explores the optimization of in-situ uranium leaching efficiency through the application of oxygen as an oxidizing agent in the lixiviant. With this objective in mind, geological characteristics of the target site were examined, followed by a ...

Presence and impact of silica and organics in uranium in-situ leaching solutions

E3S Web of Conferences
All uranium deposits of Uzbekistan mined by in-situ leaching (ISL) method belong to the so-called sandstone type and are formed on the redox barrier, with the Loyliken deposit, belonging to the so-called basal type, formed on the gley barrier, and all the rest, belonging to the roll type - on the complex gley-sulfur-hydrogen barrier.

Application of geostatistical methods for reconstruction of lithological and mineralogical structure of uranium deposit by interpolating well data

Вестник КазНУ. Серия математика, механика, информатика, 2017
During the development of uranium deposits that use in-situ leaching extraction method, mineralogical and lithological structure of sub terrain media remains unknown and is limited to the data along the wells. In order to optimize the development process,
