| 摘要 |
The present invention aims to provide a zinc 5 electrowinning anode capable of inhibiting manganese compound deposition on the anode and a cobalt electrowinning anode capable of inhibiting cobalt oxyhydroxide deposition on the anode. The zinc electrowinning anode according to the present invention is a zinc electrowinning anode having an amorphous 10 iridium oxide-containing catalytic layer formed on a conductive substrate, and the zinc electrowinning method according to the present invention is an electrowinning method using that electrowinning anode. Also, the cobalt electrowinning anode according to the present invention is an electrowinning anode 15 having an amorphous iridium oxide or ruthenium oxide-containing catalytic layer formed on a conductive substrate, and the cobalt electrowinning method according to the present invention is an electrowinning method using that electrowinning anode. 4245807.1 (GHMatters) P85859.AU.1.1 Fig. 1 - ---- Comparative Example 21 Example 2-1 s 50 0.6 0.8 1 1.2 E/V vs Ag/AgCl Fig. 2 Comparative Example 2-2 100- .- Example 2 -2 E 50- 0 -I 0.6 0.8 1 1.2 E / V vs. Ag /AgCi 4245807_1 (GHMatters)P8585Q.AU1 |
