Abstract
Se divulga un método para tratar un lodo de electrodo positivo desechado, y una aplicación. El método comprende los pasos siguientes: pretratamiento de un lodo de electrodo positivo desechado para obtener una solución de lodo; realización de coagulación electroforética y filtración a presión en la solución de lodo para obtener una fase líquida y una fase sólida; y realización de tostado por gradientes en la fase sólida para obtener un material de electrodo positivo. Según el método de la presente invención, se utiliza un lodo de electrodo positivo desechado como materia prima, y el lodo de electrodo positivo desechado se recupera utilizando procesos de trituración, clasificación, electroforesis y tostado por gradientes, sin introducir un agente floculante. La presente invención tiene las ventajas de una separación completa entre una solución de NMP y el polvo de electrodo positivo, altos índices de recuperación de materias orgánicas y metales valiosos, alta eficiencia de producción, etc., y por lo tanto no sólo mejora los beneficios económicos, sino que también reduce la contaminación medioambiental.
