Tantalum halides span the oxidation states of +5, +4, and +3. Tantalum pentafluoride (TaF 5) is a white solid with a melting point of 97.0 °C. The anion [TaF 7] 2-is used for its separation from niobium. The chloride TaCl 5, which exists as a dimer, is the main reagent in synthesis of new Ta compounds. It hydrolyzes readily to an oxychloride.
Coltan ore itself is a vessel for technology minerals tantalum and niobium. Coltan, or columbite tantalite, is an ore from which niobium and tantalum are extracted.

Oct 17, 2006· COLTAN (Columbite-Tantalite) is a dull metallic ore found in major quantities in the eastern areas of Congo. When refined, COLTAN becomes metallic Tantalum, a heat-resistant powder that can hold a high electrical charge. Columbite ((Fe, Mn, Mg)(Nb, Ta) 2 O 6: Iron Manganese Magnesium Niobium Tantalum Oxide) is the most abundant niobium mineral and is used in alloys for .

It hydrolyzes readily to an oxychloride.
The extraction and refining of tantalum, including the separation from niobium in these various tantalum-containing mineral concentrates, is generally accomplished by treating the ores with a mixture of hydrofluoric and sulfuric acids at elevated temperatures.
The most common minerals of tantalum include coltan, columbite and tantalite. Tantalite (Fe, Mn) mineral is commonly used for the extraction of tantalum. Tantalum metallurgy is categorized as the most complex and demanding metal separation process from its ores. The primary reason being the profound resemblance of tantalum with niobium, and it ...
Tantalum - Wikipedia. Tantalite (Fe, Mn)Ta 2 O 6 is the most important mineral for tantalum extraction. Tantalite has the same mineral structure as columbite (Fe, Mn) (Ta, Nb) 2 O 6; when there is more tantalum than niobium it is called tantalite and when there is more niobium than).
