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.
Deriving European Tantalum Flows Using Trade and Production Statistics Sebastiaan Deetman, Lauran van Oers, Ester van der Voet, and Arnold Tukker Summary Even though tantalum has a high economic importance and is associated with armed conflict, the use of tantalum throughout the supply chain of importing economies is not well understood.
Tantalum is also used for high temperature applications, aircraft engines, in the form of super alloys based on nickel and cobalt. Tantalum carbide is used for the fabrication of cemented carbides. Tantalum oxide is used for manufacturing of special types of glass. Fig. 4 Tantalum applications, Source: Roskill 2013 in Minor Metals Conference
How due diligence stabilised tantalum supply. Historically tantalum supply was dominated by a handful of large mines, the largest of which were in Australia, with others located in Africa, Canada, China and Russia. For several decades up to 2008 around half global supply was produced by just one company in Western Australia called Sons of Gwalia.

Niobium and tantalum are transition metals that are almost always found together in nature because they have very similar physical and chemical properties. Their properties of hardness, conductivity, and resistance to corrosion largely determine their primary uses today. The leading use of niobium (about 75 percent) is in the production of highstrength steel alloys used in pipelines ...
Tantalum is a chemical element with the symbol Ta and atomic number 73. Previously known as tantalium, it is named after Tantalus, a villain from Greek mythology. Tantalum is a rare, hard, bluegray, lustrous transition metal that is highly corrosionresistant. It is part of the refractory metals group, which are widely used as minor components in alloys. The chemical inertness of tantalum ...
Dec 30, 2019· Furthermore, with increasing tantalum production in both Brazil and Australia, the latter as a result of increased mining for lithium, diversity of production sources is also increasing. Tantalum ore is plentiful and will be in stable and reliable supply, now and going forward. You can plan on using tantalumbased capacitors with confidence.

Niobium and columbium are synonymous names for the chemical element with atomic number 41; columbium was the name given in 1801, and niobium (Nb) was the name officially designated by the International Union of Pure and Applied Chemistry in 1950. Niobium in the form of ferroniobium is used worldwide, mostly as an alloying element in steels and in superalloys.
The primary tantalum chemicals of industrial significance, in addition to K 2 TaF 7 and Ta 2 O 5, are tantalum chloride (TaCl 5), lithium tantalate (LiTaO 3) and tantalum carbide (TaC). Tantalum metal powder, including the precursor to capacitor grade powder, is generally produced by the sodium reduction of the potassium tantalum fluoride in a ...
