Chemically, tantalite is similar to columbite, and the two minerals are often grouped together in mineral guides. However, the specific gravity of tantalite is significantly higher than that of columbite. Tantalite is challenging to process and is therefore not extensively mined despite the rising demand for it as it. Processing Tantalite

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.

These elements are concentrated in the tin slag during the metallurgical processing of cassiterite. The average tantalum and niobium oxides content of the Penouta tailing is about 3 times that of the original ore. Using the classical magnetic separation, almost of the columbo tantalite was recoverd.


Also, in the processing of Greenbushes' pegmatite ore, the bulk flotation concentrate is treated with gravity separation techniques such as spiral and shaking table to remove heavy minerals, e.g., SnO 2, Ta 2 O 5 and Fe 2 O 3 (Bale and May, 1989).


Processing during this time was by gravity separation and restricted to the −2 mm fraction. The +2 mm fraction was combined with gravity processing tailings and stored in dams. Thus, a great amount of cassiterite and columbite-group minerals (CGM) was not liberated from the hosting rock and was progressively accumulated in the tailings ponds.
