Lithium Extraction (IMAGE)
Caption
Conventional lithium extraction requires several complex steps, as well as the use of acid and high temperatures, over the course of several hours. Researchers at Penn State have developed a new approach that eliminates the need for acid or extreme temperatures and takes mere minutes. In this collage, from left, is: spodumene, the mineral concentrate containing the lithium to be extracted; spodumene roasted with sodium hydroxide; leach solution, or the liquid leaching lithium from the roasted mixture; and the final product of lithium carbonate.
