Coltan - Wikipedia

Coltan (short for columbite–tantalites and known industrially as tantalite) is a dull black metallic ore from which are extracted the elements niobium and tantalum. The niobium-dominant mineral in coltan is columbite (after niobium's original American name columbium), and the tantalum-dominant mineral is tantalite.

Economic Geology of Niobium and Tantalum

Tantalum ore has characteristically grades of about 0.03% Ta 2 O 5, generally as a co-product of cassiterite and other minerals. Note that because of facile overgrinding, metallurgical recovery of columbite by crushing and milling hard-rock ore is often as low as 50%. Tantalum is silvery grey, heavy and very hard but malleable and ductile.

Tantalum Processing | TIC

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.

Tantalum - Wikipedia

Tantalum is a chemical element with the symbol Ta and atomic number 73. Previously known as tantalium, its name comes from Tantalus, a villain from Greek mythology. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant.

Tantalite & columbite mining process, tantalite ...

Tantalite has the same mineral structure as columbite (Fe, Mn) (Ta, Nb)2O6; when there is more tantalum than niobium it is called tantalite and when there is more niobium than tantalum it is called columbite (or niobite). The high density of tantalite and columbite makes the use of gravity separation the best method. Tantalite & columbite mining
