Tantalite forms a solid solution series with Columbite known as the Columbite-Tantalite series. Tantalite is the tantalum-rich member, and Columbite is the niobium-rich member. Tantalite is named after its tantalum content, and, together with Columbite, are the most important minerals containing the rare element tantalum.

The decrease of Nb/Ta in columbite– tantalite and of Zr/Hf in zircon is consistent with fractionation of a silicate melt (Linnen and Keppler, 1997, 2002). The most contentious question concerning the magmatic controls of mineralization is how the ore minerals, primarily columbite–tantalite, become saturated.

Tantalum (Ta) itself is a heavy (specific gravity of 16.6) blue-grey metallic element with a melting point of 2,996°C. It has excellent corrosion resistance, good ductility and is resistant to most acids. It displays a number of desirable physical properties - in electronics, it forms the basis of high-performance capacitors used in electrical ...

Tantalum ore is composed of both tantalum and non-tantalum containing minerals, and the Ta 2 O 5-equivalent content is typically 0.02–0.04 percent. Low-grade tantalum ore is physically concentrated (beneficiation) to a concentrate of 20–40 percent Ta 2 O 5 -equivalent at the mining site before sale to smelters ( Linnen et al., 2014 ).

From there often comes the rare metal tantalum in the form of tantalite, which is extracted from the coltan ore and used in laptops, mobile phones and game consoles. In resource-rich eastern Congo, where in addition to coltan and gold, tungsten and tin are mined, often armed groups control the lucrative mining industry. Read more ».

Coltan (short for columbite–tantalites and known industrially as tantalite) is a dull black metallic ore from which the elements niobium and tantalumare are extracted. The niobium-dominant mineral in coltan is columbite (after niobium's original American name, columbium), and the tantalum-dominant mineral is tantalite.. Columbite has the same composition and crystal symmetry (orthorombic ...
