应用氧化亚铁硫杆菌的氧化作用氧化湿法炼锌浸出液中的Ｆｅ２＋，使其转化成Ｆｅ３＋，并生成沉淀除去。对氧化反应的一些最适条件进行了研究，筛选出最佳菌株，为进一步研究奠定基础。
The oxidation of Thiobacillus ferrooxidans is used to oxidize the Fe2 + in the leaching solution of zinc hydrometallurgy so that it is converted into Fe3 + and the precipitate is removed. Some optimum conditions for the oxidation reaction were studied, and the best strains were screened, which laid the foundation for further research.
