Coltan
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 tantalite. Tantalum from coltan is used to manufacture tantalum capacitors which are used for mobile phoTantalum is a rare transition metal that is highly resistant to corrosion and has important applications in electronic equipment. In 2022, the price of tantalum was approximately 150 U.S. dollars...Tantalum price 2022 Statista

Geology, market and supply chain of niobium and tantalum—a review
Economically, significant deposits of Ta and Nb contain pyrochlore, columbite-tantalite, fersmite, loparite and strüverite. Assuming continued elasticity of Ta and Nb prices and that the law of the supply and demand applies, new sources of these metals can be developed. In the long term, there is no need to worry about Ta and Nb LA-ICP-MS U–Pb zircon, columbite-tantalite and 40Ar–39Ar muscovite age constraints for the rare-element pegmatite dykes in the Altai orogenic belt, NW China Pullen, A.

Tantalum (Ta) [Z = 73] Springer
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 groupTantalite 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 name Tantalite has been discredited by the IMA, with the more specific designations of Tantalite- (Fe) (also knownTantalite: The mineral columbite-tantalite information and pictures
