In-Situ Leach Mining of Uranium

While both these techniques produce uranium in different ways, the most common and direct way of mining uranium is known as in-situ leach (ISL) mining. ISL was first tried on an experimental basis in Wyoming during the early 1960's. Stemming from this, the first commercial in-situ leaching mine began operating in 1974.

In Situ Leach and Conventional Uranium-Recovery Methods

Jun 07, 2020 From 1972 through 1985, uranium recovery in Texas was dominated by conventional mining and milling. More recently, companies (licensees) have been using In Situ Leaching (ISL), a process that makes possible the recovery of uranium without disturbing the natural surface, generating dust, or producing waste known as tailings.
