The Boyertown plant in Pennsylvania is the only fully integrated producer of tantalum and niobium in the United States. The refinery has been operating at its 300 acre site for over 70 years. Boyertown manufactures tantalum capacitor-grade powder, including proprietary high-voltage products, as well as metallurgical products of tantalum ...
The refinery could alternatively produce a tantalum salt (K2TaF7) used in the electronic industry, dependent on customer demand. This process technique was chosen as the refinery will be able to recover and sell both niobium and tantalum creating a value-added outcome.
Vanadium (V), niobium (Nb), and tantalum (Ta) are transition metals from group V. They have partly filled d shells, so they are defined as transition elements. Vanadium and niobium are widely distributed in Earth's crust, but there are few concentrated deposits of these elements. Tantalum is less abundant in the Earth's crust; it occurs in the ...
February 2, 2020. by Brian Colwell. Niobium is considered to be a critical and strategic commodity because of the metal's specialized applications in defense, energy, high-tech industrial, and medical sectors. In addition, Niobium has no effective substitutes and the production of niobium is highly concentrated.
High concentrations of niobium and tantalum occur in granitic pegmatites both as discrete niobium-tantalum minerals and as minor constituents in the lattices of mica, garnet, tourmaline, ilmenite, zircon, and other minerals. ... niobium and tantalum are concentrated in titanium and zir
Tantalum and niobium are also known to occur in tin-bearing ore-deposits and have been concentrated and successfully extracted from the tin slags disposed as an industrial waste from cassiterite ...

Tantalum minerals with over 70 different chemical compositions have been identified. Those of greatest economic importance are tantalite, microlite,and wodginite; however, it is common practice to name any tantalum-containing mineral concentrate as 'tantalite' primarily because it will be processed for the tantalum values and is sold on that basis.The minerals are concentrated by physical ...
Processing: extraction and refining. 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. This causes the tantalum and niobium values to ...
Niobium and Tantalum—Indispensable Twins. As part of a broad mission to conduct research and provide . information on nonfuel mineral resources, the U.S. Geological Survey (USGS) supports science to understand • How and where niobium and tantalum resources form and concentrate in the Earth's crust • How niobium and tantalum resources ...

MINERALOGY AND ORE DEPOSITS The mineral processing of t a n t a l u m and niobium ores forms part of the chain which extracts ore from the ground and converts the contained metals into a useable state.
Tantalum is a specialty metal that improves conductivity and is highly resistant to heat and corrosion. AMG has a capacity to produce 300,000 pounds of high purity tantalum oxides (Ta2O5) in concentrates annually. Tantalum is characterized as a bluish-gray metal, and it is extremely ductile and malleable to low temperatures.
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 high-strength steel alloys used in pipelines ...
CBMM has installed capacity for the production of a high purity oxide that can be used to produce vacuum grade ferro- and nickel-niobium as well as niobium metal ingots via electron beam refining. The use of columbite and tantalum-bearing ores, such as tantalite, as feedstocks results in the necessity to process these materials chemically as ...
TANIOBIS is a leading global producer of high-quality tantalum and niobium-based materials. We have more than 60 years of experience in the development and manufacture of high-performance tantalum and niobium metal powders for capacitors and sputter targets, high-purity oxides for the optical industry,
Niobium is the 35th most abundant element in the earth's crust at a concentration of about 8 ppm. The two largest production sites for niobium are in Brazil with the third largest production site in Canada. The bulk of the niobium extracted is concentrated by flotation and then converted to ferro-niobium (FeNb) by aluminothermic reduction.
