Tantalum

Tantalum

Tantalite has the same mineral structure as columbite (Fe, Mn) (Ta, Nb) 2 O 6; when there is more tantalum than niobium it is called tantalite and when there is more niobium than tantalum is it called columbite (or niobite). The high density of tantalite and other tantalum containing minerals makes the use of gravitational separation the best method.

Tantalum Plansee

Tantalum occurs most frequently naturally in the form of tantalite ore which has the formula (Fe,Mn) [(Nb,Ta)O 3] 2. When the tantalum content predominates, the ore is referred to as tantalite. When more niobium than tantalum is present, it is known as columbite or niobite.
