In the late 1900s, subsurface brines with high concentrations of lithium were developed in Argentina, Chile, China and other locations. These brines could be pumped to the…

What is Spodumene?
Spodumene is a pyroxene mineral that is typically found in lithium-rich pegmatites. It is usually associated with other lithium minerals such as lepidolite, eucryptite, and petalite. Spodumene has a chemical composition of LiAlSi2O6 but small amounts of sodium sometimes substitute for lithium. Throughout most of the 20th century, spodumene was the most important ore of lithium metal. Lithium brines discovered in South America and…
