Tantalum | Plansee

Tantalum occurs naturally most frequently 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. The world's largest tantalum deposits can be found in Australia ...
