Nothing really beats good spodumene yet, and even that's pretty hard to get right at the mining stage, let alone at the refinement. Traditional brines are fine

Nothing really beats good spodumene yet, and even that's pretty hard to get right at the mining stage, let alone at the refinement. Traditional brines are fine but need scale and time and still a surprising amount of process tuning. Clays, lepidolite and alternative brine methods (DLE. Extractive beads, etc) are efficient media for extracting money from the public markets but that's about all.
