show that stable biofilm forms in cobblestone and active carbon supports, thus these two kinds of supports are suitable for immobilization of A. ferrooxidans. In batch culture, ferric iron productivity in reactor with cobblestone as supports is 0.61 g/(L?h), which is 1.49 times higher than that in suspended culture reactor. In continuous operation mode, the maximum ferric iron productivity......
Recovery of alumina and ferric oxide from Bayer red mud rich in iron by reduction sintering LI Xiao-bin(李小斌), XIAO Wei(肖 伟), LIU Wei(刘 伟), LIU Gui-hua(刘桂华), PENG Zhi-hong(彭志宏), ZHOU... to simultaneously recover caustic soda, alumina and ferric iron from red mud by sintering. Firstly, red mud rich in iron has a quite low mass ratio of alumina to silica (A/S＜1.5) as well as high iron......
