The direct precipitation of niobium and tantalum from alkaline solutions was investigated. Fig. 1 gives the precipitation yield of niobium by addition of a calcium acetate solution to a sodium hexaniobate solution at pH ~ 11.The calcium acetate complex was chosen for its high solubility in water (3.1 mol/kg of H 2 O at 25 °C) and its weak formation constant (log β (Ca(CH 3 COO) +) = 0.55 at
