This investigation has been made on reduction catalysts which are capable of extracting metallic powders from leaching solutions hydrogen reduction at high pressures. The specimens were made from Ni-Al, Ni-Cu-Al, Ni-Fe-Al, Ni-Zn, Cu-Al, Fe-Al alloys and aluminized Ni. The alloys were activated in 20%NaOH solution and their catalytic activity were compared on hydrogen consumption by aceton method. The summarized results were as follows; (1) Order of activity on hydrogen consumption; Ni-Al>Fe-Al>Cu-Al, (2) 40 to 50%Ni-Al alloys were superior to others, (3) Vanadium was successfully extracted as lower oxide precipitation by H2 in the presence of activated 40%Ni-60%Al alloy catalyst.
