The paper mainly studies the pre-oxidation process of bacteria of Arsenic-containing gold concentrates under different chloride ion concentrations.The results show that TCJ bacteria can adapt to the changes of water quality in water-head sources to meet the production requirements.On the present producing conditions,the critical value of TCJ bacterial tolerance concentration of chloride ions is 2.7 g/L.The experiment shows that the adaptability and the extent of tolerance of bacteria on Cl- is different in different raw materials and leaching system.Appropriate chloride ion is conducive to bacterial oxidation to some extent,while high chloride ions will inhibit bacterial activity and affect the pre-oxidation effect.
