There is this old 1981 article about how to recover uranium from lignite by the Oak Ridge National Labs https://www.sciencedirect.com/science/article/abs/pii/0304386X81900268 https://www.sciencedirect.com/science/article/abs/pii/030438... P.S. (Because I have been digging and reading on all the issues related to how uranium is distributed on Earth’s crust; if someone else is interested) Also a bit random to non-Europeans citation but the concentration of Uranium (in its various forms/compounds) is causing issues when we access deeper aquifers. Perhaps, something to consider also in California https://www.sciencedirect.com/science/article/abs/pii/S0048969721075239 https://www.sciencedirect.com/science/article/abs/pii/S00489...
