Tantalum | American Geosciences Institute
The estimated average abundance of tantalum in Earth's crust is about 2 parts per million (or 0.0002%). Although many tantalum-bearing minerals have been identified, the most economically significant ones are the oxide minerals columbite, microlite, tantalite, and wodginite.

Extract Tantalum & Niobium from Pegmatites
The procedure was repeated through a roll setting of 1.6 mm and a 1.67-mm screen. The combined coarse mica from the three screens comprised 41% of the feed weight and contained 4.9% of the tantalum and 7.9% of the niobium. This lost tantalum and niobium was considered part of the mica lattice rather than unliberated material.
