Abstract. A stable and continuous leaching process for niobium and tantalum extraction from ferrocolumbium tantalum (FT) was developed. The effects of initial concentration of HF and H 2 SO 4, grinding fineness, leaching time, and temperature on the leaching rate of Ta, Nb, Fe, and Si were studied.Experimental results show that the …
Introduction. Niobium (Nb; Z = 41) and tantalum (Ta; Z = 73) are two group V elements which remain largely unknown to the general public even if their unequaled properties make them essential for many key sectors.For example, Nb is a strategic ingredient in the manufacture of high-strength low-alloy (HSLA) steels [1]. The addition …

Historically, tantalum was discovered in 1802 by Anders Ekeberg. Its mining gained prominence during the 20th century as the demand for electronics soared. Unfortunately, tantalum mining has been linked to conflicts, especially in regions where regulations are minimal. Tantalum is found in various parts of the world.
