20 Bagger. Aspiring Lithium Triangle Producer!!, page-1853

Oops, I don't know as I'm not a specialist chemist! (I've taught some chemistry but that is different). I would say that Li is one of the more reactive metals though - up there with Na (sodium) - so I would not want to heat the brew up too much! Even at lower heat - say 30-40C - the brine would evaporate way faster than temps like 5-15C which would probably be the case for many months of the year at Salar del Rincon. On the other hand, maybe when the lithium is in compound form (e.g. lithium carbonate) there isn't too much of a problem with heating? This is where we need specialist knowledge ...
