Test on Ferrite Removal by Kaolin Bioleaching Process and Dynamics Analysis
摘要
Abstract
Bioleaching of Fe ( Ⅲ ) oxides impurities from kaolin sample was carried out using indigenous iron reducing microorganisms, where the effect of pH and temperature on the efficiency of Fe ( Ⅲ ) removal was investigated. The important parameters such as pH, UoRp and glucose varied with the process of Fe ( Ⅲ ) reduction in kaolin have been analyzed. In addition, the Logistic model was used to investigate the effect of pH on Fe ( Ⅲ ) reduction from kaolin. Results showed that both pH and temperature impacted the reduction capacity. The pH and temperature optimum for Fe ( Ⅲ ) reduction were 7 and 30 ℃, respectively. During the process of Fe ( Ⅲ ) reduction, pH, UoRp , and glucose decreased with the increasing of reduction capacity.关键词
