tantalite, tantalum-rich variety of the mineral columbite (q.v.) with the chemical formula (Fe,Mn)(Ta,Nb) 2 O 6. Tantalite is the principal ore of the metal tantalum . This article was most recently revised and updated by Amy Tikkanen .
These tantalite concentrator types include vibrating shaker tables and alluvial washing machines, and they can be used alongside more precise separation tools to prepare raw materials. But they can also be used alone when there's less need for accuracy. Whether you are separating bauxite or minerals from beach sand, a solution can be …
Niobium and tantalum are critical metals that are necessary for many modern technologies such as smartphones, computers, cars, etc. Ore minerals of niobium and tantalum are typically associated with pegmatites and include columbite, tantalite, wodginite, titanowodginite, microlite and pyrochlore. Solubility and crystallization mechanisms of …

tantalite (coltan), which normally contains mixtures of columbite and tantalite with up to 60% Nb content. Columbite and tantalite are variations of the general formula (Fe,Mn)(Nb,Ta)2O6, and the mineral is called tantalite when the tantalum content exceeds the niobium content, and columbite (niobite) when the composition is vice versa2.
The columbite group is a solid solution with varying proportions of Nb or Ta in its composition. According to the International Mineralogical Association (IMA), 'tantalite' or 'coltan' are not scientific names, yet they are widely used. Many specimens commonly named tantalite are actually minerals of the columbite or tapiolite group ...

Tantalite is actually an ore of tantalum that is mined for its use in various electronic equipment, including mobile phones. This is chemically the same as the columbite. This is the reason why you may also see it as columbite-tantalite in some areas. It's also known by 2 other terms, depending on the precise composition of the stones.

Manganotantalite. Manganotantalite is an intense red to reddish brown variety of tantalite with a high manganese and low iron composition. Prized for its exceptional dispersion, this mineral yields beautiful faceted gemstones, thanks in large part to its orthorhombic crystal structure. However, faceted gems are very limited in availability.
The principal source of tantalite or tantalum is an isomorphous series of minerals that contain columbium (niobium), iron, manganese and tantalum oxides. Tantalum and columbium have strong geochemical affinity and are found together in most rocks and minerals in which they occur. Tantalite-columbite, which is the major source for tantalum,
