Having read the 'chat' this morning (please chaps, tone it down a bit, everybody has a different opinion and we're all here to try and make a few quid) I feel I need to point out the basis of the lithium extraction technology; it only works on water soluble salts, ie a solution.
Taking one we all know, common salt (sodium chloride) when it dissolves in water it dissociates into its ions (sodium Na+) and chlorine (Cl-) which will then naturally gravitate towards a cathode and anode of an electrical circuit. The clever bit is to design a membrane that allows only targeted atoms through. Using this example again, sodium is a group one metal in the periodic table with atomic number 11 and lithium a group 1 metal with atomic number 3. Essentially lithium is a smaller atom, so the 'holes' in the membrane have to be engineered smaller to allow it through and keep the undesirables out.
Hence in a nutshell it is ideal for use with the salares of South America, keeps water use to a minimum, but in its current form cannot be used to separate hydrocarbons.
No, I'm not a chemist (ex R-R engineer) but just an interested layman.
I hope this helps.
