Method for Removal of Iron from Clay by Bacterial Leaching

摘要

PURPOSE: A method for removing iron of clay mineral using biochemistry leaching is provided to prevent the leaching of aluminum during the iron removal process of clay mineral using an organic acid, and to reduce the usage of water. CONSTITUTION: The method for removing iron of clay mineral using biochemistry leaching consists of a step for preparing a mineral solution containing raw mineral to be processed; and a step for processing the mineral solution by adding metallic chloride reduction bacilli, and iron ion adsorbent. In the biochemistry leaching process using microorganisms, shewanella putrefaciens IR-1 is used.
