Some well informed people pointed out that lithium is one of the Earth’s most abundant minerals and that historically, when there is demand, new ways are found of extracting minerals wherever they may be found.

Now it’s 2020. New and novel ways are being found to extract commercial-grade lithium from what otherwise are industrial waste products. Researchers at the Karlsruhe Institute of Technology in Germany are using a new process to extract lithium from the groundwater used by geothermal energy plants in the Upper Rhine area. Ordinarily, after making heat or electricity, that water is pumped back underground, even though it contains quite a lot […]
