Before lithium ends up in an EV battery, it has to be "dug" out of the ground first — and the world does this in two almost opposite ways. One is blasting rock mountains in Australia and roasting them at a thousand degrees. The other is pumping brine from beneath the South American desert and drying it in the sun for a year. The difference in "cost" and "speed" between these two paths is the key to why lithium prices spiked 10x and then crashed 80% in just a few years. Who survives, who goes bust, and why Africa and China have become the new variables everyone has to watch.
