Identity Help : difference between columbite and tantalite
In short, columbite-Fe is more common than columbite-Mn and in turn are both much more common than tantalite-Mn and the fourth example, tantalite-Fe, is actually very scarce. There are paragenetic guidelines. Associated iron and manganese bearing minerals tend to have a similar ratio of elements, but they need to be coeval.

Tantalite-(Fe): Mineral information, data and localities.
From ferrous iron content and the Greek mythological Tantalus, for the difficulty of dissolving the mineral. The original material with Fe>Mn was called Tantalite, subsequent name changes recognized the compositional variability of the series. Type Locality: ⓘ Upper Bear Gulch, Tinton Pegmatite Mining District, Lawrence Co., South Dakota, USA.

Extraction of Niobium and Tantalum Oxides From Columbite
Nb and Ta values are present in the form of ferro-columbite and tantalite phases, whereas cassiterite (SnO 2) is the primary Sn phase. The SEM micrograph of the feed sample shown in Figure 1 (b) depicts a smooth surface morphology with particles of different shapes and sizes that range from 5 to 100 microns.

Chemistry of columbite-tantalite minerals in rare metal granitoids
Compositionally, columbite-tantalite of the Li-albite granites is constrained between MnNb 2 O 6 and MnTa 2 O 6 (the Ta/(Nb+Ta) atom. ratio ranges between 0.10 and 0.80). This low to high ratio and the association of columbite-tantalite with topaz, fluorite and lithian micas (in the series zinnwaldite-white mica) indicate a higher solubility ...

Tantalite Meaning Properties And Powers
It is chemically similar to Columbite, so you may also see it called columbite-tantalite in some places. It is also known by two other names depending on the exact makeup of the stones. The more common one is the manganese rich type which is called manganotantalite or less commonly, the iron rich variety called ferrotantalite.
