WebLithium hat an der Erdkruste einen Anteil von etwa 0,006 %. Es kommt damit etwas seltener als Zink sowie häufiger als Kobalt, Zinn und Blei in der Erdkruste vor. Obwohl Lithium häufiger als beispielsweise Blei ist, ist seine Gewinnung durch die stärkere Verteilung schwierig. Im Trinkwasser und einigen Nahrungsmitteln wie Fleisch, Fisch, … WebSome of the known methods of isotope separation have not been applied to lithium and should be evaluated experimentally. Since the primary objective is to devise means of obtaining lithium 7, the method chosen will probably be different from one that would have the aim of concentrating the lighter, less abundant isotope.
