Natural Occurrence

  • Elemental lithium does not occur naturally
  • Mineral sources include spodumene, lepidolite, and petalite, amblygonite
  • Some natural brines contain high concentrations of lithium in dissolved lithium compounds such as lithium carbonate

Hazards

Production

Extraction

Electrolysis

  • Electrolysis of a molten mixture of lithium chloride and potassium chloride. At a 45:55 ratio, they melt at 300°C. In the presence of oxygen and moisture in the air, the lithium will react.
