EstablishedTantalum stripping: NH4F 1.1 mol/L with NH3 0.4 mol/L, against NH4F 0.3 mol/L with NH3 0.1 mol/L for niobium.
Reported for this deposit
Tantalum separated from niobium not at extraction but at stripping: the same extractant loaded both, and tantalum required a more alkaline solution at nearly four times the fluoride concentration niobium needed.
