What is the price of niobium?
Currently, niobium prices range from US$45 per kilogram (US$45,000 per tonne) for standard ferroniobium metal and greater than US$50 per kilogram for niobium pentoxide (Nb2O5).
How much does a pound of tantalum cost?
FORTUNE — Tantalum is a rare element in high demand. To control tantalum is to control a key part of the 21st-century supply chain: Half of all tantalum mined goes into electronic capacitors, which store an electric charge. And it is expensive — $130 per pound, vs. its rarer cousin, tungsten, at $28.
What is 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.
Is tantalum a rare metal?
Tantalum is a grey, heavy and hard metal with high corrosion resistance and the highest known ability of all metals to store electricity. It is very rare, averaging 2 ppm in the earth’s crust, and is remarkable for its unsurpassed performance in the diverse end uses that it serves.
Why is niobium valuable?
Its uses include sophisticated applications in the construction, automotive, aerospace, shipbuilding and oil and gas industries, such as the construction of bridges, steel structures for buildings and pipelines. In its pure metal form, niobium is incredibly versatile.
Is niobium rare?
Niobium is a rare element with a share of 1,8 · 10 in the earth’s crust−3 %.
How much is tantalite worth?

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.
What is tantalite use for?
More than half of tantalum’s use is for electrolytic capacitors and vacuum furnace parts. The element is also used to make chemical process equipment, nuclear reactors, aircraft and missile parts.
Where is tantalite mined?
In terms of resources, whether currently exploited or not, in addition to Australia and Brazil there are other significant resources in China, the DRC, Ethiopia, Mozambique, Nigeria, Russia and Rwanda. Tantalum is also produced in Brazil, Malaysia and Thailand as ‘tin slag’, a by-product of tin mining and smelting.
How much is tantalum worth?
In 2019, the average monthly price of tantalum ore decreased to about $158 per kilogram of Ta2O5 content in October from about $173 per kilogram of Ta2O5 content in January.
