| Abstract: |
| Slurry electrolysis was successfully utilized to process As-rich antimonic gold concentrate in semi-pilot tests. The results show that antimony recovery is 97% above. Gold and most antimony and sulfur are enriched in leached residue. Hazards of generation of vast arsenic-alkali residue and low-concentration SO2 gas were avoided. The consumption of industrial hydrochloric acid is 286 kg for one ton production of antimony. Moreover, the total electricity consumption is about 3 389 kWh and the direct current consumption is 1 318 kWh for one ton production of antimony. |
