Investigations into the analytical chemistry of tantalum, niobium, and their mineral associates. XXVII. Observations on manganese, and the analysis of tantalite
[en] In nature, the main source of tantalum is an isomorphous series of minerals containing oxides of tantalum, niobium, iron and manganese, which are collectively known as columbinetantalite (coltan). Upgraded Ta 2 O 5containing tin slags are also used as a secondary source of, either naturally occurring or synthetically produced as concentrates from tin .

Manganese is usually found in the adult body at the level of 10 – 20 mg, most of which is found in the bone, liver and kidneys. Manganese is an antagonist to phosphorus, magnesium, and iron. Whereas, phosphorus, magnesium, iron and calcium are antagonists to manganese.
Manganese (Mn) Manganese ... Niobium (Nb) Niobium stabilises ... Tantalum (Ta) Tantalum is a refractory metal which is highly corrosion resistant. It is part of the refractory metals group, which are widely used as minor components in alloys and precipitation hardening stainless steels. Titanium (Ti)
· Tantalum occurs naturally in the mineral columbitetantalite. It's mainly found in in Australia, Brazil, Mozambique, Thailand, Portugal, Nigeria, Zaire and Canada. Separating tantalum from niobium requires either electrolysis, reduction of potassium fluorotantalate with sodium or reacting the carbide with oxide.
India's tantalum, niobium and vanadium ore import volume rose % YoY in May 2021 [0818] Netherlands' ferroniobium export volume increased % YoY in Apr 2021 [0818] Belgium's ferroniobium import volume fell % MoM in Apr 2021 [0817]
Relatively rare, tantalum is about as abundant as occurs, with niobium, in the columbite–tantalite series (in which columbite [FeNb 2 O 6] and tantalite [FeTa 2 O 6] occur in highly variable ratios) and the pyrochlore–microlite series of minerals. Native tantalum metal with some niobium and traces of manganese and gold occurs sparingly in Russia in placers in the .

· Niobium (symbol: Nb; atomic number: 41) is a metallic element with soft, gray and ductile properties. In nature, it is often found along with pyrochlore mineral while its processed form is used in the manufacture of highgrade structural steel and superalloys. The name comes from Niobe, a figure in Greek mythology, who was Tantalus' daughter.

Metal with High Melting Point – Top 2. Rhenium (Re) Rhenium is a silverwhite metal with the second highest melting point (3180 °C) after tungsten and has the highest boiling point. Commercial rhenium is generally powdered and can be pressed or sintered into a highdensity solid in vacuum or hydrogen, with a density of more than 90% of the metal state.

Tantalum Capacitors – Overview and Explanation Tantalum Capacitors . Capacitor Overview . In an electric circuit, the capacitor is a passive, two terminal device that can statically store electric energy between it's terminals by using a technique called charge separation. The charge separation phenomenon occurs in capacitors due to the dielectric material placed between its metal plates.
