tantalum ore typically

Locations of Deposits

Pegmatites are more expensive to process than brine, but typically have higher ore concentrations (0.60%). Lithium is also extracted from sedimentary rocks, including clays, which can have up to 0.7% concentrations, but this is a much less common form of deposit than brines or pegmatites (Gruber, 2011).
