Tantalum in the environment

Tantalite (Fe,Mn)Ta 2 O 6 is the most important mineral for tantalum extraction. Due to lanthanide contraction and hence their similar properties, niobium and tantalum replace each other isomorphically in minerals. Tantalite has the same mineral structure as columbite (Fe,Mn)Nb 2 O 6 and both are commonly found together.
