Years ago when I was trying to learn about commodities I bought a copy of the CRB yearbook. It does not look like they cover Lithium. https://www.barchart.com/cmdty/resources/crb-yearbook I tried investigating on my own, got caught up in numerous emails from firms pumping their companies. Any idea on how I can learn about the big picture stuff going on pertaining to Lithium, mining, and purification thereof? I wish the CRB yearbook covered it.
Look at this link: https://www.usgs.gov/centers/nmic/lithium-statistics-and-information Lots of statistics and factsheets. Maybe you can find what you are looking for there?
