Abstract

En la presente invención se describe un método de regeneración cíclica de residuos de fosfato de hierro y una aplicación del mismo. El método comprende: mezclar y disolver residuos de fosfato de hierro y líquido ácido para obtener una solución de hierro-fósforo; tomar una pequeña parte de una solución de hierro-fósforo para preparar un precipitante de fosfato de hierro; luego agregar el precipitante de fosfato de hierro a la solución de hierro-fósforo restante para una reacción para obtener un precipitado de fosfato de hierro dihidratado; usar parte del precipitado de fosfato de hierro dihidratado como precipitante para la reacción en el siguiente lote; y preparar el resto del precipitado de fosfato de hierro dihidratado en fosfato de hierro anhidro. Según la presente invención, el precipitante de fosfato de hierro se prepara para usarse en la preparación posterior de fosfato de hierro, el fosfato de hierro preparado cada vez se puede usar para la preparación siguiente de fosfato de hierro, y el proceso es simple en el proceso de preparación, necesita líquido alcalino solo en una etapa de preparación del precipitante, no utiliza el líquido alcalino en la producción posterior, es más respetuoso con el medio ambiente, tiene una consistencia de producto alta, costos bajos, productividad alta, consumo de energía bajo y adecuado para la producción industrial a gran escala.
