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.
Tantalum Ore a natural mineral formation containing tantalum in compounds and quantities that make its industrial extraction technically feasible and economically expedient. A distinction is made between tantalum ores proper, in which Ta2O5:Nb2O5 ≥ 1, and complex tantalum-niobium ores. The main minerals of tantalum ores are columbite-tantalite ...

Tantalum has a unique ability to store and release energy, which is why the electronics industry . consumes more than one-half of tantalum production. Tantalum-based components can be exceptionally small, and other elements cannot serve as substitutes without degrading the performance of electronic devices.
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.
Also tantalum can be in the structure of cassiterite, SnO2, in substitution of Sn, being in some cases an ore of Tantalum In columbite tantalite and microlite niobium and tantalum constitute a solid solution, with their relative ratios distributed in different ways, giving place to uniform or zoned minerals.

Production of raw materials. Extraction or production of tantalum raw materials of all kinds is widespread, whether by primary industrial mining, artisanal mining, as a secondary mineral or as a byproduct. Brazil is currently the major producer. Significant quantities are also produced in China, the DR Congo, Russia and Rwanda.
Tantalum is a chemical element with the symbol Ta and atomic number 73. Previously known as tantalium, its name comes from Tantalus, a villain from Greek mythology. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant.

and Brazil were the leading global producers of tantalum mineral concentrates in 2014. The Democratic Republic of the Congo increased tantalum production in 2013 and 2014 and replaced Brazil as the second leading producer. Figure 1 shows share of 2009–13 average world tantalum mine production, and
Apr 16, 2015· Mine Production: 85 tons. Tantalum production in Mozambique dropped over the past year, as the country produced 115 tons of the metal in 2013, and just 85 tons in 2014. The largest licensed tantalum project in the country is the Muiane Project, which is wholly owned by Pacific Wildcat Resources (TSXV:PAW).
Tantalum (Ta) is ductile, easily fabricated, highly resistant to corrosion by acids, and a good conductor of heat and electricity and has a high melting point. The major use for tantalum, as tantalum metal powder, is in the production of electronic components, mainly tantalum capacitors.
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.
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.
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.
Australia has historically been the world's largest producer of tantalum (as tantalite concentrates), providing approximately half of the world's mine output through mining operations at Greenbushes 250 kilometres (km) south of Perth in Western Australia (WA) and …

About 70% of 2008 tantalum world production resulted from the mining of tantalum-containing minerals with an additional 7% from synthetic tantalum ore and the remainder from recycling (Roskill Information Services Ltd., 2009b, p. 8). The tantalum industry, traditionally shrouded in secrecy, is
Tantalite Ore Mineral Deposits - Nigeria which is situated in the Western part of Africa has a significant and excellent deposit of tantalite, which is world class and is vastly deposited mostly in the northern parts of Nigeria, some of these deposits have been mined and some though discovered and in huge deposits have remained untouched.
