Ocean manganese nodules are the important non-ferrous metal resources. Its smelting can produce ammonia leaching residue which has high value for good adsorption ability,including high catalytic and excellent electrochemical characteristics. The paper was introduced from waste water in absorbent and refining function,desulfuration,material preparation and ect. It summarized the state of art research in recent years. The ocean manganese nodules in ammonia leaching residue can effectively remove heavy metal ions to purify the wastewater to have a good desulfurizing effect. It also can be widely used in ionic sieve,coating,the application of modified asphalt and other materials. Ocean manganese in nodules ammonia leaching residue has a broad resource utilization prospect,and it will be of a higher industrial utilization value.
