Tantalite

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

Tantalite is used as an ore of tantalum and niobium and as mineral specimens and occur in pegmatites. Tantalite is largely found mixed with columbite in an ore called coltan. Coltan is the colloquial African name for columbite-tantalite, a metallic ore from which are extracted the elements niobium and tantalum. In appearance, coltan is a dull
