| Abstract: |
| New type biological oxidation reactor adopted external air-forced system. Sulfide oxidation in new bioreactor improves a little than that in traditional biological reactor under the feeding rate of 1.2︰1. Gold cyanidation leaching rates of oxidation slag in new bioreactor rise by 0.5~1.3 percent point and by 0.2~1.3 percent point respectively compared with those of traditional biological reactor under the condition of feeding rate of 1.1︰1 and 1.2︰1 respectively. |
