Study On The Removal Of Heavy Metal In Acid Mine Drainage Using Red Mud

Red Mud (RM) is the waste material formed during the production of alumina, the Acid Mine Drainage (AMD) is the waste water which is low pH and the concentration of heavy metal is heavy. The RM and AMD contaminated seriously. According the geochemical engineering, using the RM to remove the heavy metals in AMD and eliminate the pollution of them at the same time. Using the ICP-MS and so on to analyze RM and AMD, the AMD had a high concentration of acid, it's concentration of heavy metal is greatly exceed of the standard. The red mud is porosity scaffolds and had large specific surface area. Its chemical component is...
