Growth Characteristics and Dephosphorization Effect of Mixed Bacteria
Microbiological leaching technology，because of its low production cost and less investment, simple process, high recovery rate, as well as environment-friendly characteristics, gradually become an important new technology are widely used，open up broad prospects for humanbeing, resources and the environment sustainable development. In this paper, the growth characteristics of Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans in mixed culture has been studied, explored mixed bacteria leaching phosphorus, a harmful component in iron ore, from a kind of iron ore. The results show that mixed bacteria has strong ability to produce acid., and have stronger oxidation activity to energy source --Fe2+. Mixed bacteria can significantly increase the rate of dephosphorization from iron ore in low concentration pulp. It goes against mixed bacteria reproduction when pulp concentration increased, makes dephosphorization decreased.
