How is tantalum traded?
Tantalum isn’t traded on any public commodities exchange. It isn’t really bought and sold in pure form. Instead, it is sold as tantalite ores from which the metal can then be extracted. The price of the tantalite is very much dependent on the demand as well.
What is coltan and why is it important?
Coltan is used primarily for the production of tantalum capacitors, used in many electronic devices. Coltan is important in the production of mobile phones; and tantalum capacitors that are used in almost every kind of electronic device.
Where is tantalite found?
It has been found in Australia, Brazil, Canada, Colombia (Guainía and Vichada), Egypt, northern Europe, Madagascar, Namibia, Nigeria, Rwanda, The Democratic Republic of Congo, the United States (California, Colorado, Maine, and Virginia), and Zimbabwe.

What is the price of tantalite?
What’s the difference between tantalum and tantalite?
As nouns the difference between tantalite and tantalum is that tantalite is (mineralogy) a dark-brown mineral that is an ore of tantalum and niobium, of the chemical formula (fe]], mn) ta2[[oxygen|o6 while tantalum is a metallic chemical element (symbol ta) with an atomic number of 73.
What is tantalite used for?
Tantalite is the most widespread tantalum mineral and makes for an important ore of the industrially useful metal. Tantalum is used in alloys for strength and higher melting points, in glass to increase the index of refraction, and in surgical steel, as it is non-reactive and non-irritating to body tissues.
When did coltan mining begin?
Coltan is mined using techniques developed for gold mining in the 1800s. The work is difficult and dangerous, with workers panning for coltan in large craters in stream beds, with the average worker producing less than one kilogram of coltan a day.

What is the difference between tantalite and tantalum?
How is tantalite mined?
Most tantalum mines are open pit; some are underground. The process of mining tantalum involves blasting, crushing and transporting the resulting ore to begin the process of freeing the tantalum. The ore is then concentrated at or near the mine site, to increase the percentage (by weight) of tantalum oxide and niobium.
