Tantalite is purchased and sold solely on its Ta2O5 content. Nb2O5 content is not figured into the payable value for tantalite. If the material contains a minimum amount of 50% Nb2O5 with a small percentage of Ta2O5 it would be traded as columbite. Columbite is purchased and sold on the Nb2O5 + Ta2O5 content, known as Combined Pentoxide (CPO).

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
Columbite, also called niobite, niobite-tantalite and columbate, is a black mineral group that is an ore of niobium and tantalum. It has a submetallic luster and a high density and is a niobate of iron and manganese, containing tantalate of iron. Columbite …
The ultimate objective of the columbite–tantalite beneficiation process for ore from the Jinzhulong Ta–Nb deposit is to maximize the recovery of Ta 2 O 5 and Nb 2 O 5 while comprehensively considering the subsequent utilization of other valuable components with minimum processing cost in a marketable preconcentrate to be sold as byproducts.
Figure 2: Hydrometallurgical Processing of Niobium and Tantalum. Columbite and tantalite, either naturally occurring or synthetically produced as concentrates from tinslag, are digested with hydrofluoric acid at elevated temperatures. The accompanying elements are dissolved along with the niobium and tantalum, which form the complex heptafluorides

Columbite has the same composition and crystal symmetry (orthorombic) as tantalite. In fact, the two are often grouped together as a semi-singular mineral series called columbite-tantalite or coltan in many mineral guides. However, tantalite has a much greater specific gravity than columbite, more than 8.0 compared to columbite's 5.2.
Supply from Taboca was disrupted in 2016 and imports from Nigeria were supplemented by Brazilian columbite and by columbite-tantalite from Central Africa. Supply from Taboca resumed in 2017. In 2019, Estonia imported material only from Taboca as its feedstock and still does, with production continuing normally.
