tantalum and niobium extraction and beneficiation process

Niobium Extraction, Refining Production

The use of columbite and tantalum-bearing ores, such as tantalite, as feedstocks results in the necessity to process these materials chemically as described in the tantalum section. The purified niobium-containing process stream is generally converted to niobium hydroxide by the introduction of ammonia, followed by washing, filtration, and calcining to the oxide. Get price

Separation of niobium and tantalum in liquid extraction

Niobium, also known as columbium, is one of the new industrial metals likely to play an important role in industrial processing in the near future. Its high melting point (4376F) and low cross section for neutron absorption (1.1 barns) makes it of special interest to the Atomic Energy Commission. Since tantalum, which invariably accompanies niobium in its ores, has a somewhat higher cross Get price

niobium processing

2020/8/15The tantalum is extracted as a fluoride in the organic solution, while niobium remains in the aqueous residue, or raffinate. The niobium is then precipitated from solution as a fluoride by the addition of ammonium hydroxide, and the filter cake is dried and roasted, or calcined, at 900–1,000 C (1,650–1,800 F) to obtain niobium pentoxide.
