Ta is present in columbite–tantalite, columbite and pyrochlore as an oxide and its concentrations in these minerals are 26.1%, 4.8% and 0.6%, respectively. The solubility of Ta present in each mineral in SLF is shown in Fig. 3. Ta present in these minerals show fast solubility rate (<100 h). The dissolution life-time ( τ) in columbite is 34 ...Web
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.Web

Tantalum comes from the processing and refining of tantalite. Tantalite is the common name for any mineral ore containing tantalum. Most tantalum mines are open pit; some are underground. The process of mining tantalum involves blasting, crushing and transporting the resulting ore to begin the process of freeing the tantalum.Web
Tantalum metal powder, including the precursor to capacitor grade powder, is generally produced by the sodium reduction of the potassium tantalum fluoride in a molten salt system at high temperature. 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.Web
That Zimbabwe has a significant and diverse mineral resource base is not in doubt. With estimates that Zimbabwe has the second largest reserves of chrome and platinum after South Africa and potential to supply about 25% of the global diamond market, mining can play a catalytic role in Zimbabwe's economic revival, stabilization and eventual growth.Web
