Reinjection (SunResin were partnered with Tibet Summit)
One of their other partners is anASX company with a project in the US.

This is from the above link :


Brine Reinjected.

SunResin also have announced developments with a number of other Argentine brine developers.
So Evaporation which extracts the water from the salar into large ponds (land use) & doesn't replace it.
Extraction & reinjection (at least in the US) for a Aluminum absorbent process which washes the lithium off with water (high water use).
Extraction & reinjection with Ion exchange beads where it does not require the same amount of land (ponds) nor water (washing).

Horses for courses, these are the 3 process route choices I see as practical reality now.
Every brine resource developer will have different criteria on which to base their competitive choice on.
HotCopper won't factor into this technical assessment.
