Tantalum - Wikipedia

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, blue-gray, lustrous transition metal that is highly corrosion-resistant. It is part of the refractory metals group, which are widely used as minor components in alloys. The chemical inertness of tantalum ...

The key role of mica during igneous concentration of tantalum

May 27, 2014  Tantalum and niobium are commonly referred to as “geochemical twins” owing to their strong chemically similarity. However, economic concentrations of each element are found in very different geochemical environments: tantalum deposits are associated with granitic pegmatites, whereas niobium is mainly mined from carbonatites (Kuzmenko 1961; Linnen et al. 2014).

Coltan - Wikipedia

Coltan (short for columbite–tantalites and known industrially as tantalite) is a dull black metallic ore from which the elements niobium and tantalum are extracted. The niobium-dominant mineral in coltan is columbite (after niobium's original American name columbium), and the tantalum-dominant mineral is the tantalite.. Tantalum from coltan is used to manufacture tantalum capacitors which ...

A review on extractive metallurgy of tantalum and niobium ...

Dec 01, 2020  The density of a coltan bearing ore is dictated by the tantalum grade and is generally between 5.3 and 7.8 g/cm 3 (Mirji et al., 2016). However, when the tantalum content is low, other minerals being present, such as cassiterite and wolframite could possess densities close to that of colombo-tantalite.
