A novel approach for Ta and Nb extraction consisting of the pre-treatment of a coltan-bearing ore with an ammonium bifluoride sub-molten salt and subsequent acid leaching has been studied. The effects from ore granulometry, ammonium bifluoride (ABF) to ore mass ratio, temperature and duration of fluorination on the degree of Ta and Nb extraction were …
The density of a coltan bearing ore is dictated by the tantalum grade and is generally between 5.3 and 7.8 g/cm 3 (Mirji et al., 2016). However, when the tantalum content is low, other minerals being present, such as cassiterite and wolframite could possess densities close to that of colombo-tantalite.

The metal can also be produced by the carbon or aluminium reduction of the oxide or the hydrogen or alkaline earth reduction of tantalum chloride. The choice of process is based on the specific application and whether the resultant tantalum will be further consolidated by processing into ingot, sheet, rod, tubing, wire and other fabricated ...
The coltan ore (short for columbite-tantalite and known industrially as tantalite). In Africa, Nigeria is rich in coltan/columbite resources. Columbite deposits occur in Plateau, Kogi, Kano, Nasarawa, Kaduna, and Bauchi states, mainly in the placer deposits of cassiterite. In Africa, miners must upgrade coltan ore to a saleable grade (like 50-60% level) using whatever method, but in …
As mentioned earlier, the purpose of the coltan ore processing in this work is to generate a leachate rich in Ta and Nb, offering the possibility of their downstream separation via solvent extraction. ...

Coltan ore spawns in the overwold in one scattered on 1000 block wide area similar but not exacly to australian ore, the location is random. To find the area use Coltass (upgraded compass) which will always point to the center of the deposit. It drops Coltan (not affected by Fortune enchantment) It is the major resource for Tantalium production.
Paradoxically, considering Coltan's use in the high technology industry, the vast majority of Coltan Ore is mined through a rather primitive process, similar to that of Gold in the 1800s. Sadly, in many parts of the world, this is linked to, to say the least, undesirable working conditions and an unnecessarily great environmental impact.
