          Tantalum -  Coltan

It's found in the mineral tantalite. Tantalum is known as a rare transition metal, has a great metallic shine, resists corrosion very well, is very hard and has a grayish blue. Is a physiologically inert element so that is used for various applications.

The Democratic Republic of Congo holds 80% of estimated global reserves of coltan. This mineral is considered a highly strategic non-renewable resource.


The largest global tantalum awakens desires it is an ideal compound for transmitting electricity so it is considered a superconductor and is also capable of storing charge and release it gradually. Therefore it has become an essential input to produce miniature components that power electronic and telecommunications equipment.


Global demand for tantalum has grown steadily since 1995 and its current price is over $ 400 per kilogram
