Tantalum minerals contain 12 to 84 percent tantalum pentoxide; however, tantalum ores are low grade and contain only 0.01 to 1 percent tantalum pentoxide, which is equivalent to 0.1 to 10 kilograms per metric ton. As a result, to produce concentrates of tantalum, tantalite ore must be separated from other minerals in the ore.

After the ore is refined into powder, the output must equal the weight of the input in a mass balance check. The refined ore is sealed into trackable containers scanned with a smartphone every time they're loaded or unloaded from ships or trucks. Step 3: Manufacturing in USA. The refined tantalum is shipped to a manufacturer.

Tantalum occurs in great variety of oxide minerals. The most common are columbite-tantalite, (Fe,Mn)(Nb,Ta)2O6, and microlite, (REE, U, Y, Ca,Na)2(Ta,Nb)2O6(O,OH,F)), which belong to the pyrochlore group minerals. Also tantalum can be in the structure of cassiterite, SnO2, in substitution of Sn, being in some cases an ore of Tantalum In ...
