A Note on Some Tantalum

Interest in the tantalum-niobium minerals has been greatly stimulated in Western Australia by the fact that these rare minerals occur at numerous localities in that State, and in the adjoining parts of the Northern Territory, sometimes in mineable concentrations, as at Wodgina and Greenbushes. A large proportion of the world's tantalum comes from these deposits. Get price

Tantalum

The niobium-dominant mineral in coltan is columbite (after niobium's original American name, columbium), and the tantalum-dominant mineral is tantalite. Tantalum from coltan is used to manufacture tantalum capacitors, used in electronic products. It is also used in high-temperature alloys for air- and land-based turbines. Tantalum minerals Get price

Sample Preparation Guides

Niobium is named from Niobe the daughter of Tantalus in Greek Mythology. It was named Columbium (Cb) at the time of its discovery in 1801. This name was used until IUPAC adopted the name niobium in 1950 after more than a century of controversy. Niobium (Nb) and tantalum (Ta)Tantalum (Ta), much like Zr and Hf, have nearly identical atomic radii. Get price

Rare Metals Report on Tantalum Niobium by Jacob

Jul 19, 2011The most common tantalum and niobium minerals are the columbite-tantalite (also known as coltan) group minerals. When tantalum outweighs niobium the mineral is called tantalite, when niobium outweighs tantalum the mineral is Jacob Securities Inc., 199 Bay Street, Suite 2901, Toronto, ON M5L 1G1 +1-416-866-8300 Page 4 Get price

Tantalum

Tantalum is sometimes, but only rarely, found uncombined in nature. It occurs mainly in the mineral columbite-tantalite, which also contains other metals including niobium. It is mined in many places including Australia, Canada and Brazil. There are several complicated steps involved in separating the tantalum from the niobium. Get price
