tantalite mining states

Tantalite: Mineral information, data and localities.

An obsolete group name for minerals with the general formula (Mn,Fe)(Ta,Nb) 2 O 6, equivalent to the Tantalite-(Fe)-Tantalite-(Mn) Series.Generally mangan-dominant members are more abundant in nature. Many specimens called tantalite actually belong to the columbite series or tapiolite series. Visit gemdat.org for gemological information about Tantalite.

Where is Tantalum Mined TIC

Tantalum minerals with over 70 different chemical compositions have been identified. Those of greatest economic importance are tantalite, microlite,and wodginite; however, it is common practice to name any tantalum-containing mineral concentrate as 'tantalite' primarily because it will be processed for the tantalum values and is sold on that basis.The minerals are concentrated by physical

Tantalite Wikipedia

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).
