Tantalite-(Mg): Mineral information, data and localities.

Tantalum is found mainly in the minerals tantalite [(Fe,Mn)Ta 2 O 6] (easily confused with columbite, the niobium analogue of tantalite) and euxenite. Ores are found in Australia, Brazil, Mozambique, Thailand, Portugal, Nigeria, Zaire and Canada. It is also a byproduct from the extraction of tin. Abundances of tantalum in various environments

Buyers of Tantalite (coltan) ore / concentrate

The most common minerals of tantalum include coltan, columbite and tantalite. Tantalite (Fe, Mn) mineral is commonly used for the extraction of tantalum. Tantalum metallurgy is categorized as the most complex and demanding metal separation process from its ores.

Columbite-(Fe): Mineral information, data and localities.

Sources: Tantalum is found primarily in the mineral columbite-tantalite (Fe, Mn)(Nb, Ta) 2 O 6 or Coltan. Coltan is a conflict resource. Tantalum ores are found in Australia, Zaire, Brazil, Mozambique, Thailand, Portugal, Nigeria, and Canada. A complicated process is required to remove tantalum from the ore, as tantalum always occurs with niobium.

Tantalite-(Fe): Mineral information, data and localities.

There are three types of rocks that host the mineralization, namely, igneous, sedimentary, and metamorphic (Table 8.7).Examples of igneous rocks are porphyry copper deposits in granite, platinum–palladium–chromium–nickel deposits in dunite, as well as peridotite, gabbro, norite and anorthosite, tantalite, columbite, and cassiterite in pegmatite.

Coltan - Wikipedia

Tantalum is sometimes, but only rarely, found uncombined in nature. It occurs mainly in the mineral columbite-tantalite, which also contains other metals including niobium. It is mined in many places including Australia, Canada and Brazil. There are several complicated steps involved in separating the tantalum from the niobium.

Tantalite-(Fe) Mineral Data

From ferrous iron content and the Greek mythological Tantalus, for the difficulty of dissolving the mineral. The original material with Fe>Mn was called Tantalite, subsequent name changes recognized the compositional variability of the series.

Tantalite | mineral | Britannica

Tantalite forms a series with the mineral columbite. In fact the two are often grouped together as a semi-singular mineral call columbite-tantalite in many mineral guides. Tantalite is the most widespread tantalum mineral and makes for an important ore of the industrially useful metal.

History. Tantalum was discovered in Sweden in 1802 by Anders Ekeberg, in two mineral samples – one from Sweden and the other from Finland. One year earlier, Charles Hatchett had discovered columbium (now niobium), and in 1809 the English chemist William Hyde Wollaston compared its oxide, columbite with a density of 5.918 g/cm 3, to that of tantalum, tantalite with a density of 7.935 g/cm 3.

Columbite | mineral | Britannica

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.

COLTAN (Columbite-Tantalite) is a dull metallic ore found in major quantities in the eastern areas of Congo. When refined, COLTAN becomes metallic Tantalum, a heat-resistant powder that can hold a high electrical charge. Columbite ((Fe, Mn, Mg)(Nb, Ta) 2 O 6: Iron Manganese Magnesium Niobium Tantalum Oxide) is the most abundant niobium mineral and is used in alloys for improved strength.
