Abstract

By means of aqueous oxidation in ammonia solution, metallic zinc and sulfur in marmatite were leached. In this study, it was found that the concentration of ammonia was extremely influenced on the oxidation ratio of Zn and S, and the more the leaching temperature was low, the more their leaching ratio was decreased. The maximum leaching ratio to the contents in marmatite was obtained at the following conditions. Particle size 270 mesh above, $NH_3$ conc, 25%, Press. 4.2 kg/$cm_2$, Temp.$ 60 ^{\circ}C$, Time 20hrs. Leaching ratio; Zn 55% and S 50%.
