Abstract
As a basic study on recovery of valuable metals such as vanadium and nickel from metal oxide obtained from waste orimulsion ash, we conducted selectively leaching of vanadium and nickel using $Na_2CO_3$ leaching and ammoniacal leaching, respectively. The 97% of vanadium was selectively leached at an optimum experimental condition, 50g/L $Na_2CO_3$, pulp density 50g/L, and 35% $H_2O_2$ 50ml/L, $25^{\circ}C$... for 1 hr, whereas no nickel was leached. In ammoniacal leaching study, 95% of nickel was selectively leached at the optimal experimental condition, $NH_4OH\;2M,\;(NH_4){_2}SO_4$ 1.5M, pulp density 50g/L, 25, for 4 hr along with 3% of vanadium.
