文献标识码:A Dephosphorization technology of iron ores by Acidthiobacillus ferrooxidans JIANG Tao, JIN Yong-shi, LI Qian, YANG Yong-bin, LI Guang-hui, QIU Guan-zhou...-leaching were investigated. The results show that Acidthiobacillus ferrooxidans(A.f) can remove phosphor from iron ores and nutrient medium without phosphorus is more effective for the removal than......
gene with the type strain Acidthiobacillus ferrooxidans ATCC 23270 and 100% identities of iro gene (CDS) with A. ferrooxidans strain Fe-1. These results show that the strain can be considered as Acidthiobacillus ferrooxidans. Because of the high activity of oxidizing ferrous and sulfide mineral, strain GF was used in bioleaching of marmatite. The Zn concentration is 0.273 g/L under the steriled......

There have been several... of pentlandite using modified powder microelectrode with Acidithiobacillus ferrooxidans attached or without on the mineral powder surface. Cyclic voltammetry (CV) results show that at a low potential of about......

(Acidthiobacillus ferrooxidans,At.f)的浸矿效果不同.MLY和At.f对含砷金精矿的浸出机理也不同;接种MLY的矿浆中,可能主要是溶液中的细菌将Fe2+氧化为Fe3+,再由Fe3+氧化溶解矿物,即以间接浸出作用为主;而接种At.f可能首先是At.f被吸附到矿物表面,通过细菌与矿物之间的某种界面作用引起矿物溶解,矿物溶解产生的Fe2+被游离菌氧化成为Fe3+,从而溶解矿物,即At.f...) Abstract: To comprehend the bioleaching mechanisms of arsenic-containing gold concentrates with moderately thermoacidphilic iron-oxidizing bacterium MLY and Acidthiobacillus ferrooxidans(At.f......
