Tantalum VS Niobium – Magic Metal Tantalum
Tantalum and niobium belong to one family in the periodic table. Due to their similar physical and chemical properties, as well as growing together in the same ore body, they are known as the twin of metals. Tantalum and niobium were discovered in 1801 and 1802 by Charles Hatchett, a British chemist, and Ekberg, a Swedish chemist.
Tantalum And Niobium
Production. After the separation from the other minerals, the mixed oxides of tantalum Ta2O5 and niobium Nb2O5 are obtained. The first step in the processing is the reaction of the oxides with hydrofluoric acid: Ta2O5 + 14HF → 2H2 [TaF7] + 5H2O, and. Nb2O5 + 10HF → 2H2 [NbOF5] + 3H2O.

1. Introduction. Niobium and tantalum are present in the crust of the earth at 1 × 10 − 3 and 2 × 10 − 4 wt.% respectively. They are encountered together in minerals, mostly in the form of tantalite or columbite (Agulyansky, 2004).Metal recovery is usually achieved by dissolving the mineral in aqueous HF, followed by liquid–liquid extraction.

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.

Summary. Niobium and tantalum do not occur naturally as free metals. The charge to ionic ratio of tantalum and niobium results in strong bonds being formed with oxygen; in fact, most niobium–tantalum minerals are oxides, rather than silicates, sulfides or phosphates. Three types of niobium and tantalum deposits are: carbonatite-hosted ...
