While many people think of lithium only in the context of batteries, it is a critical material supporting development of diverse new technologies in the 21st century. Global supply chains of past years must be rapidly expanded to meet new demands. Traditionally, lithium has been produced from both hard-rock mines and from highly saline brines brought to the surface and concentrated through evaporation. New mines can be developed, but surface concentration of lithium brines is limited to specific areas and is coming under increased environmental scrutiny. To address the demand, exploration companies have identified brines in deep saline aquifers as huge potential new lithium resources, but there are many challenges to finding, appraising and developing them. This course is aimed at helping the student understand and address these challenges and develop a plan to extract these resources. Visit the SEG website for registration and more info.
