Reversing Mother Nature

How does ISL uranium mining work? talked to North America’s leading In Situ Leach (ISL) uranium mining engineers to have them explain the process step-by-step. They explained ISL mining is really just reversing the process of Mother Nature.

One of North America’s leading In Situ Leach (ISL) engineers Harry Anthony, who is also the recently appointed chief operating officer of Uranium Energy Corp, told, “In the mining stage, we are reversing Mother Nature’s process by adding oxygen, oxidizing the uranium from a valence of +4 to a valence of +6.” Mr. Anthony explained how in its natural, reduced environment, uranium exists as a solid in the +4 valence. The uranium was oxidized at one time, but then reduced by Mother Nature. By drilling wells into a uranium-mineralized orebody, circulating the water and adding oxygen to it, the uranium is again mobilized. Once it is soluble, it can be captured, processed and made into nuclear fuel.


Rising uranium prices have begun attracting investors, who have now become curious about how uranium is produced in the United States. A three-part series premiered on the internet website,, explaining the environmentally friendly In Situ Leach (ISL) uranium mining process. Top North American ISL geological and engineering experts were interviewed for their advice and expertise. The top ISL “gurus” explain the entire ISL process, step by step in the feature entitled, “Reversing Mother Nature.” Visit this webpage for the entire feature:
