The new TANIOBIS brand will take effect on July 1, 2020. "Our new name is a combination of the two key raw materials used in our production operations, tantalum and niobium," explains Masakazu Kanzaki, Vice Chairman & CEO at H.C. Starck Ta&Nb. "The characters 'i' and 's' at the end stand for 'innovative solutions'.
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.

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 are always found together, usually in minerals of the tantalite–columbite series in pegmatites, granites, carbonatites and alkaline igneous rocks. Tantalum and niobium are associated with tin-bearing aplite–pegmatite–greisen dykes in northeastern Victoria. The Walwa tinfield, including the Mount Alwa and Bounce mines ...
Indeed, until the discovery of the world's pyrochlore deposits in the 1950s, niobium was a by-product of tantalum mining, with increasing demand ensuring that it was highly valued and highly priced. All of the world's main tantalite mines are hosted in pegmatite ore bodies, including Wodgina, Greenbushes, Marropino and Bernic Lake in Canada.
About this book. Rare Earth Elements (REE) as well as tantalum and niobium are of tremendous importance because of their specific high-technology applications. The contributions gathered in this volume give an up-to-date survey on the mineralogy, primary ore deposits, prospecting, processing and applications of REE, Ta, and Nd, making this ...
Niobium occurs associated with tantalum in the mineral columbite [ (Fe, Mn)O. (Nb, Ta) 3 O 5 ], which has been considered the most important source of niobium. Columbite deposit is found in Africa. Tantalum occurs associated with niobium in tantalite (Ta 2 O 5 .FeMnO). Tantalite deposites are found in USA, Brazil, Australia, and South West Africa.

Tantalum and niobium do not occur naturally as free metals, and are mostly found as components in various oxide minerals such as columbite, tantalite and pyrochlore. Ores containing these minerals are typically beneficiated to produce a tantalum or niobium concentrate, which may include: Crushing Grinding Gravity separation Magnetic separation
tantalum, and the ore is imported either directly or as a concentrate. Therefore, domestic processing of columbium and tantalum may begin after the milling step shown in Exhibit 2. Tantalum and columbium are extracted from the source materials, imported concentrates, and tin slags, by digestion and liquid-liquid extraction. (Teledyne Wah Chang ...
