The price of the tantalite is very much dependent on the demand as well. The price of tantalite ore rose from about $75 per kilo in 2010 to more than $270 per kilo on 2011 and 2012. But the price has dropped since then. However, some experts point to expected growth in the electronics, aerospace, and power industry to boost the price back up.
Tantalum is a highly corrosion-resistant transition metal that occurs in the mineral tantalite. The major use for tantalum is in electronic components such as capacitors and high-end resistors. It is also used to proudce superalloys with high melting points, strength, and good ductility for jet engines, nuclear reactors, and other advanced industries.

Tantalum-based components can be exceptionally small, and other elements cannot serve as substitutes without degrading the performance of electronic devices.
Tantalum Price Trends 2015. ... Shifts in tantalum production. ... prices for tantalite ore rose from $54 per pound in 2010 to $125 in 2011, and were sitting around $118 in 2013. ...
World tantalum mine production has undergone an important geographic shift since the start of the 21st century when production was predominantly from Australia and Brazil. Beginning in 2007 and through 2014, the major sources of tantalum production from mines dramatically shifted to the DRC, Rwanda, and some other African countries.

Tantalum is a hard, blue-grey metal that is highly resistant to corrosion. Tantalite is the most important tantalum ore mineral and large deposits of tantalum exist in Australia.
Alibaba.com offers 1,479 tantalite ore products. About 14% of these are other ore, 7% are other metals & metal products, and 1% are rare earth & products. A wide variety of tantalite ore options are available to you, such as lump, mine, and fines (powder).
The extraction and refining of tantalum, including the separation from niobium in these various tantalum-containing mineral concentrates, is generally accomplished by treating the ores with a mixture of hydrofluoric and sulfuric acids at elevated temperatures.
Coltan (short for Columbite-Tantalite and known industrially as Tantalite) is a dull black metallic ore from which the elements Niobium and Tantalum are extracted. The Niobium-dominant mineral in Coltan is Columbite (after Niobium's original...

Tantalite ((Fe, Mn)(Ta, Nb) 2 O 6: Iron Manganese Tantalum Niobium Oxide) is the most widespread tantalum mineral and makes for an important ore of the industrially useful metal.Tantalum (Ta) is a gray, heavy, and extremely hard metal. When pure, it is ductile and can be drawn into fine wire, which is used as a filament for evaporating metals such as aluminum.
are another source of tantalum. The leading niobium ore and concentrate producers were Companhia brasileira de metalurgia e mineração (Cbmm) in brazil and iamGold Corporation (Niobec mine) in Canada.

It is primarily found in the mineral tantalite, and usually occurs along with niobium, an element which shares many chemical and physical characteristics with it. Tantalum containing minerals are mostly found in pegmatite ore bodies. Tantalum-bearing tin slags (a by-product of tin smelting) are an additional source of tantalum.

Another benefit to Morefield mine tantalum is its origin in the USA guarantees it is 'conflict-free' and the cost of guaranteeing the chain of ownership is minimal compared to African tantalite. Tantalum concentrate/ore is often referred to as 'Coltan'.
Apr 24, 2017· Tantalum comes from the processing and refining of tantalite. Tantalite is the common name for any mineral ore containing tantalum. 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 mineral group tantalite [(Fe, Mn)Ta 2 O 6] is the primary source of the chemical element tantalum. It is chemically similar to columbite, and the two are often grouped together as a semi-singular mineral called coltan or "columbite-tantalite" in many mineral guides.
