Tantalum was first discovered in Sweden by Anders G. Ekeberg in 1802. The name tantalum originates in Greek mythology; Tantalus was the father of Niobe, and niobium's properties are very similar to those of tantalum. Tantalum is the element 73 on the periodic table and has a gray blue color in its metallic form. It has a density of 16.69 g·cm−3. It has a melting point of 2850 Celsius ...
Worldwide production stands at about 2,000 tons a year. As a result, H.C. Starck Ta&Nb is in a leading position on the market in terms of development and production of tantalum and niobium powder. Although tantalum and niobium may not be very well known as raw materials, they do play an essential role in day-to-day life.
However, there are a number of other applications for niobium metal and its compounds. Although niobium has many applications the majority is used in the production of high-grade structural steel. The second largest application for niobium is in nickel-based superalloys. Niobium-tin alloys are used as superconducting magnets.

Production. After the separation from the other minerals, the mixed oxides of tantalum Ta2O5 and niobium Nb2O5 are obtained. The first step in the processing is the reaction of the oxides with hydrofluoric acid: Ta2O5 + 14HF → 2H2 [TaF7] + 5H2O, and. Nb2O5 + …
Tantalum market has been under pressure due to the shortfalls of supplies, while niobium producers expect to experience healthy levels of demand increases and market growth.
Tantalum smelting method Tantalum smelting process. Tantalum niobium ore is the main raw material for the production of tantalum, but it is often associated with a variety of metal, so the main step is the decomposition of tantalum smelting concentrates, purification and separation of tantalum and niobium, produced pure compound of tantalum and niobium, finally, we can produce metal.
of niobium or tantalum. Brazil, Canada, and Australia are the leading global producers of niobium and tantalum mineral concentrates. Brazil produces the greatest amount of niobium mineral concentrates (~90 percent), while Australia and Brazil together lead in the production of tantalum mineral concentrates.

Tantalum Products. N eo Rare Metals is a conflict free producer of high purity tantalum products from columbite ore and secondary (recyclable) materials. Our tantalum metal, compounds and advanced materials are critical components for the manufacturing of electronics, superalloys in the aerospace sector, and corrosion resistance coating systems.
Tantalum occurs most frequently naturally in the form of tantalite ore which has the formula (Fe,Mn) [(Nb,Ta)O 3] 2. When the tantalum content predominates, the ore is referred to as tantalite. When more niobium than tantalum is present, it is known as columbite or niobite.
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 fact that tantalum and niobium complexes form in fluoride solutions not only supplements fundamental data on the coordination chemistry of fluoride compounds, but also has a broad practical importance. This type of solution is widely used in the technology of tantalum and niobium compounds in raw material digestion, liquid-liquid extraction ...
Tantalum and Columbi um Production Exhibit 2 illustrates the processing of tantalum and columbium. There is no domestic mining of columbium or tantalum, and the ore is imported either directly or as a concentrate. Therefore, domestic processing of columbium and tantalum may begin after the milling step shown in Exhibit 2.
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 ...

Niobium is located in the same period as molybdenum in the periodic table. Its density and melting point are therefore comparable to those of molybdenum. In the same way as tantalum, niobium is prone to hydrogen embrittlement. The heat treatment of niobium therefore takes place in a high vacuum and not in a hydrogen atmosphere.
Tantalum concentrate is the feed source used by the processors to produce tantalum capacitor powders and metallurgical products. The concentrate is also used to produce pure tantalum pentoxide (Ta2O5) primarily utilized in the production of optical glass and lithium niobate. The primary feedstock is ore mined at the Volta Grande Mine operations.
