The mixed bacterial was obtained by enrichment from acid water and soil of asbestos mining area in Sichuan province and was domesticated.Primary studies on the influence factors of tellurium during leaching low-grade tellurium ore by mixed bacteria in shake flask tests were carried out.The results showed that when the temperature was 30 ℃ the leaching effect of mixed bacteria was the best, and the leaching rate reached 66.2％ after leaching for 15 days with the pulp concentration of 1％.When the initial pH value was 1.5 ～ 2.0, the leaching rate of tellurium ore was high by the mixed bacterial.When the pH value was 1.5, the leaching rate was the highest and reached 67.8％.The leaching effect of tellurium ore was good by the mixed bacteria with a lower pulp concentration( 1％ ～2％ ), the leaching rate can reach 66.6％ after leaching for 15 days.The verification experiments showed that the leaching rate of tellurium can reach 75.8％ after leaching for 15 days at a temperature of 30 ℃, with an initial pH value of 1.5, pulp concentration of 2％.%从四川石棉矿区酸性水及土壤中通过富集技术获得混合菌,对其驯化,并在摇瓶中对该混合菌浸出低品位碲矿中碲的影响因素进行了初步探索.结果发现,该混合菌在30℃时浸矿效果最好,在1%的矿浆浓度下,经过15 d的浸出,浸出率达到66.2%;在初始pH值为1.5～2.0时,混合菌对碲矿有较高的浸出率,pH值为1.5时的浸出率最高,为67.8%;在矿浆浓度较低(1%～2%)时,混合菌对碲矿的浸出效果较好,15 d浸出率可达到66.6%.验证实验表明,温度为30℃,初始pH值为1.5,矿浆浓度为2%,浸矿15 d后碲的浸出率可达到75.8%.
