In situ recovery ISR is one of the two primary extraction methods that are currently used to obtain uranium from underground. ISR facilities recover uranium from low-grade ores where other mining and milling methods may be too expensive or environmentally disruptive. This method uses the following process, as illustrated in the figure to the ...

1. INTRODUCTION TO IN SITU LEACH URANIUM MINING IN THE USA Since the start of commercial in-situ leach ISL uranium mine production in the USA in 1975, ISL uranium mining has grown from an obscure, experimental technology to the dominant U.S. producer. U.S. uranium production reached its ma imum level in 1980 when 16,809 MTU were produced.

In Situ Uranium Mining Energy Education

In situ uranium mining is a method of mining used to obtain uranium that is deep underground. Dissolving solutions are injected into the uranium deposit to allow the uranium to flow more freely, allowing it to be pumped up through a system of wells to the ground above where it can be processed. When uranium ore is deep underground, removing the overlying rock can be extremely difficult and ...

Mining. In general, uranium mining is relatively similar to other kinds of mining unless the ore is very high grade. In this case, special mining techniques are used to limit worker radiation exposure and to ensure the safety of the environment and general public. Depending on the deposit, uranium is mined in one of three ways open pit, underground, or in situ recovery.
