A stepwise separation process for niobium and tantalum from tantalite by extraction and ion exchange was developed. A tantalite mineral was dissolved by a fusion technique using ammonium bifluoride as flux. Tantalum and niobium form stable anionic fluoride complexes in fluoride solutions.
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.
