2019-7-1 iron from oxide minerals can be used for the removal of this element from clays for improvement of filler and coating properties via the action of metabolic products.[4]. The solubilization of iron occurs through the action of organic acids and other excreted metabolites, acting as complexing

INTRODUCTION Bio leaching of clay materials containing iron metal sulfides or oxides can be accomplished by using microorganisms. Earlier reports revealed that more than 11 species [1] of prokaryotic IIJJEE microorganisms found to be performing the solubilization of metal sulfides or oxides for effective removal of metal from clay materials.

Clay has many applications; however, its utility depends on its physical and chemical composition. High-grade clays in the country are lacking due to the presence of some inherent impurities such as iron. The presence of iron in clay minerals has a profound effect on their physico-chemical properties.

2005-12-6 3C 2 O 4 2-+ Fe 3+ [Fe(C 2 O 4) 3] 3-. Recent investigations have focused mainly on the study of iron extraction from kaolin, whose main component is kaolinite. In this work the method of iron removal by oxalic acid in a clay sample was adopted. For this purpose, an experimental design was carried out using a 2 k Factorial Design, where k is the number of factors [6].
