LKE towards TOP-5, page-12798

I think that the most relevant part of your post is where you say "Not about LKE..."
The article is all about how difficult it is to extract lithium from geothermal brines.
"A company called Lilac Solutions, which has created an ion-exchange technology to separate lithium from a variety of brines, has decided to avoid working with the superheated poisonous brine of the Salton Sea because it’s so difficult to handle. Along with the problems that come from managing a 600-degree liquid, anyone who is trying to extract lithium also has to ensure that these other dangerous materials in the brine don’t escape into the air we breathe."
Interesting article though.
