摘要：In the process of copper biohydrometallurgy, a small amount of copper extractant organic phase will remain in raffinate by entrainment of dissolving and emulsion droplets. Copper extraction organic phase can poison the bacteria and further affect the bioleaching process.The effects of organic extractants containing ketoximes and oximes on the metabolism of Acidithiobacillus ferrooxidans (A.ferrooxidans) and its bioleaching efficiency were studied. The results showed that the presence of organic phase inhibited bacterial metabolism and reduced its leaching activity.
