In-Situ Leach Uranium Mining: A Review

Energy Exploration & Exploitation, 1983
This paper describes a current technique (ISL) in uranium mining, i.e. by solution or ‘leaching’. Although it is not yet widespread, it promises a relatively cheap and efficent means of extracting uranium from orebodies in sandstone deposits, such as those of the USA, Australia and Japan.

Molecular‐Scale Insights Into Mesopore Formation in ZSM‐5

Small Structures
Zeolite‐base leaching, also known as desilication, is widely applied at laboratory and industrial scales to create hierarchical zeolites with mesopores, which improve transport properties in numerous catalytic processes. Applicable to different catalytic

The study of change in extraction degree under the influence of oxidizers while leaching Uranium ore with sulfuric acid

Вестник КазНУ. Серия математика, механика, информатика, 2017
Sulfuric acid is extensively used in uranium production with In-Situ Leaching method. The influence of various components on the extraction degree has to be studied in order to optimize the solution spending and extraction degree of uranium.
