To extract from lithium bearing clays by mixing with salt and water, the lithium comes out in solution, whoo, that’s easy!
Can’t say I really believe it. That lithium does come out in brines is obvious as that’s a major source, extraction from brines. But I tend to think that that’s a result of geological timescale processes, not factory ones.
Of course, I know absolutely nothing about this it just doesn’t seem “right” to me.
