FaceDeer@kbin.social 3 months agoRare-earth element is a specific technical term. Lithium is absolutely not among them.
One of the main sources lithium is extracted from is brines. That is, it's already in the water and we take it out.

You’re right, brain fart. Still rare earths aren’t rare, and lithium isn’t non-toxic. Ballpark lead? Where’s a toxicologist when you need them. The ores also tend to contain little lithium: Lead and tin are rarer but have very pure ores in rather dense deposits, in that sense mining lithium is nearly as annoying as mining rare earth metals.
