Tantalum | Geoscience Australia
In late 2016, spodumene was reported as present in the tantalite ore at the pegmatite deposit with the commencement of metallurgical test work, exploration and resource drilling 19. A maiden lithium mineral resource was released in 2017 20 and a further resource estimate was published in 2018 21 .
Tantalum Deposits in the United States
Tantalum primarily occurs in the mineral tantalite, which may be found in carbonatites, alkaline granite-syenite complexes, and lithium-cesium-tantalum (LCT) pegmatites. The largest Ta deposits can be found in Australia, where the Greenbushes and Wodgina Mines have been producing Ta from pegmatites since the late 1880s.
The African Tantalite Mining Industry
Tantalite is challenging to process and is therefore not extensively mined despite the rising demand for it as it. Processing Tantalite. Tantalite appears in granites and other hard rock deposits like carbonites and pegmatites that contain extensive rare-earth elements. Most tantalite mines are open pit, though there are some underground mines.

Mineral-deposit model for lithium-cesium-tantalum pegmatites
Lithium-cesium-tantalum (LCT) pegmatites comprise a compositionally defined subset of granitic pegmatites. The major minerals are quartz, potassium feldspar, albite, and muscovite; typical accessory minerals include biotite, garnet, tourmaline, and apatite. The principal lithium ore minerals are spodumene, petalite, and lepidolite; cesium mostly comes from pollucite; and tantalum mostly comes ...

Tantalite - Wikipedia
Tantalite occurs in granitic pegmatites that are rich in rare-earth elements, and in placer deposits derived from such rocks. It has been found in Australia, Brazil, Canada, Colombia (Guainía and Vichada), Egypt, northern Europe, Madagascar, Namibia, Nigeria, Rwanda, The Democratic Republic of Congo, the United States (California, Colorado, Maine, and ia), and Zimbabwe.

Global Tantalum Production, Conflict Minerals and The U. S ...
The production shift from Australia was a result of high extraction costs and an unfavorable exchange rate, which meant that mining tantalum ore in Australia was no longer economically viable. The shifting of tantalum production to the DRC, Rwanda and other African nations raised the concerns about tantalum's status as a conflict mineral.
