Pharmacology

Lithium is an element with atomic symbol Li, atomic number 3, and atomic weight 6.941.

How it is made

Recovery of the ore, spodumene, followed by concentration by froth flotation, conversion to lithium chloride, and electrolysis from an anhydrous lithium chloride-potassium chloride mixture.

High-temperature extraction from spodumene by sodium carbonate, solar evaporation of lake brines.

Recovered from natural brines, electrochemical processes, reduction of the oxide with magnesium or aluminum, Hanson, U.S. patent 2,028,390 (1936)
