The ilmenite and pyrite informs on the reducing conditions of formation of the ore while the lanthanum value points to its lithosphere origin. The ore is not radioactive by virtue of its very low Thorium content [17-19]. This reason also suggests why some Ta/Nb minerals cannot be shipped out of the country, because of their levels of radioactivity.

Ilmenite - Infogalactic: the planetary knowledge core

Tantalum/columbite granites are of economic interest when the columbite content of the ore ranges from 0.001% to 0.01% and the tantalite up to 0.2%. These deposits are most common in Nigeria (Africa). Because they are a low-grade ore, they do not represent significant economic value. Pegmatite deposits are the most abundant.

Tantalum ore has characteristically grades of about 0.03% Ta 2 O 5, generally as a co-product of cassiterite and other minerals. Note that because of facile overgrinding, metallurgical recovery of columbite by crushing and milling hard-rock ore is often as low as 50%. Tantalum is silvery grey, heavy and very hard but malleable and ductile.
