    en.wikipedia.org/wiki/Tantite Tantite is a rare tantalum oxide mineral with formula: Ta 2 O 5.Tantite forms transparent microscopic colorless triclinic - pedial crystals with an adamantine luster. It has a Mohs hardness of 7 and a high specific gravity of 8.45. Chemical analyses show minor inclusion (1.3%) of niobium oxide.. It was first described in 1983 for an occurrence in a pegmatite in the Kola peninsula, Russia.

  • Tantalite - Wikipedia

    en.wikipedia.org/wiki/Tantalite The mineral group tantalite [(Fe, Mn)Ta 2 O 6] is the primary source of the chemical element tantalum.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. However, tantalite has a much greater specific gravity than columbite (8.0+ compared to columbite's 5.2).
