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 …
