Tantalum producers in 2015 with Rwanda being the main producer. Australia was the main producer of tantalum prior to the 2010s, with Global Advanced Metals (formerly known as Talison Minerals) being the largest tantalum mining company in that country.
A typical human contains 21 parts per billion of niobium. Niobium is in the minerals columbite and pyrochlore. [19] There are 2 parts per million of tantalum in the Earth's crust, making it the 51st most abundant element there. Soil contains on average 1 to 2 parts per billion of tantalum, and seawater contains 2 parts per trillion of tantalum.

The mineral group tantalite [(Fe, Mn)Ta 2 O 6] is the primary source of the chemical element tantalum, a corrosion (heat and acid) resistant metal.It is chemically similar to columbite, and the two are often grouped together as a semi-singular mineral called coltan or "columbite-tantalite" in many mineral guides.

Wodginite is a manganese, tin, tantalum oxide mineral with the chemical formula Mn 2+ (Sn,Ta)Ta 2 O 8. It may also include significant amounts of niobium . [ 2 ] [ 3 ]
Béhierite is a very rare borate mineral, [2] and the tantalum endmember of a (Nb,Ta)BO 4 solid solution series formed with schiavinatoite, its niobium analogue. [4] [3] Béhierite is also one of the most simple tantalum minerals. It contains simple tetrahedral borate anions, instead of more common among minerals, planar BO 3 groups.
