After being oxidated for 34 h, and then the contents of Fe2+ in the 9K liquid solution with 4×10-4mol/ L xanthates, dithiophosphates and D-250 added inreased from 4.03 g/L to 4.64, 4.77 and 5.91g/L, respectively. After leaching for 35 d, the leaching rates of Zn are 92% and 61% respectively. It shows that the flotation reagents (xanthates, D-250) have great effect on the activity of bioleaching bacteria.

研究结果表明：添加4×10-4mol/L的丁基醚醇、乙基黄药、丁胺黑药，氧化34 h后，使 K液体培养基中的Fe2+质量浓度由4.03 g/L分别增加至4.64 g/L， 4.77 g/L和5.91 g/L；浸出35 d后，精矿中的浸出率分别为92%和61%，这进一步验证了浮选药剂对浸矿细菌活性的影响。
