Wang et al. (2009) developed a process for the recovery of Nb and Ta as oxides from alkaline leachates described in Fig. 7. It involves initial addition of a certain amount of Nb 2 O 5 to the ore. The enriched ore is fused with potassium oxide at about 400 °C and the obtained products are subsequently leached with water.

The primary ore of tantalum is the columbite-tantalite group. The columbite group is a solid solution with varying proportions of Nb or Ta in its composition. According to the International Mineralogical Association (IMA), 'tantalite' or 'coltan' are not scientific names, yet they are widely used.

The general chemical formula of niobium tantalite is AB2O6, and the two are collectively referred to as niobium tantalite. A is iron and manganese, and B is niobium and tantalum. The magnetic susceptibility of niobium tantalite is (22.1～37.2)×10-6. The dielectric constant of ferroniobium is 10-12, and the dielectric constant of tantalite is 7-8.

This may depend on the rate of the decomposition and leaching of the tantalite ore and/or the solubility of the solute to be extracted (Agulyansky, 2004; Zhu and Cheng, 2011; Nete et al., 2014).

Niobium and tantalum, characterized by high melting point, remarkable corrosion resistance, and good cold workability, are widely used in steel, petrochemical, electronics, and aerospace [1, 2].The main ore sources for the production of tantalum and niobium include pyrochlore, microlite, tantalite, columbite, and columbo-tantalite …
