Isolation: isolation of tantalum appears to be complicated. Tantalum minerals usually contain both niobium and tantalum. Since they are so similar chemically, it is difficult to separate them. Tantalum can be extracted from the ores by first fusing the ore with alkali, and then extracting the resultant mixture into hydrofluoric acid, HF.

Tantalum and Niobium – the keys to the markets of the future

Tantalum and Niobium – the keys to the markets of the future Tantalum is among the rarer elements in the earth's crust. It ranks between thorium and caesium in frequency and is therefore rarer than lanthanum, lead, gallium or boron. Even niobium, which always occurs in association with tantalum, is ten times more available.
