What Are Lithium Minerals?
Lithium minerals are naturally occurring minerals that contain significant amounts of lithium.
These minerals occur mainly in:
- granite pegmatites
- lithium-rich brines
- rare-element deposits
- hydrothermal systems
Most hard-rock lithium production comes from pegmatite-hosted lithium minerals.
