Get PriceTantalum is obtained chiefly from the mineral tantalite, although it also occurs in euxenite, samarskite, and some other rare minerals. The major sources of tantalum ore are Australia, Brazil, and Canada. Tantalum is almost always found in association with niobium; separation of the two metals is difficult.
Get PriceIf the quantity of tantalum exceeds niobium, the mineral ore is labeled as tantalite. On the other hand, the mineral source is identified as columbite when the opposite occurs [10]. Commercial tantalum is used mostly in its the powdered form to make electronic devices [10]. The unstable tantalum180 is the rarest isotope in the universe [10].

Get PriceColtan is the industrial name for columbite–tantalite, a dull black metallic mineral from which the elements niobium (formerly "columbium") and tantalum are extracted. The niobiumdominant mineral is columbite, hence the "col" half of the term. The mineral concentrates dominated by tantalum are referred to as tantalite.
Get PriceTantalum is incorporated into a variety of alloys, conferring high melting point, ductility, strength, and corrosion resistance. Tantalum carbide is one of the hardest materials ever made. At high temperatures, tantalum has good 'gettering' ability. Tantalum oxide films are stable, with desirable dielectric and rectifying properties.

Get PriceTantalum Ore a natural mineral formation containing tantalum in compounds and quantities that make its industrial extraction technically feasible and economically expedient. A distinction is made between tantalum ores proper, in which Ta2O5:Nb2O5 ≥ 1, and complex tantalumniobium ores. The main minerals of tantalum ores are columbitetantalite ...
Get PriceTantalum also appears in medical and health care applications. Thanks again to its oxide coating, tantalum is inert to bodily fluids and is highly biocompatible. Its high density makes it an efficient Xray absorber, so tantalum stents and implants are easier for surgeons to image and monitor using Xrays during implantation.
