Iron oxide existence in kaolin is biologically induced, so it is better to apply a biological process for removing it from clays by exploiting microorganisms (Poorni and Natarajan, 2013). Interaction of microbes with clay minerals conserves the clay structure, fertility, and chemistry of the soil through the cation exchange and pH buffering ...
