In Situ Leach Mining (ISL) of Uranium World Nuclear

In Situ Leach Mining of Uranium (Updated October 2017) In 2016, 48% of world uranium mined was from ISL operations. Most uranium mining in the USA, Kazakhstan and Uzbekistan is now by in situ leach methods, also known as in situ recovery (ISR). ISL mining of uranium is undertaken in Australia, China, and Russia as well.
