Abstract

Procedimiento para preparar fertilizantes complejos en suspensión, mediante el tratamiento con amoniaco de un líquido obtenido por digestión de mineral fosfato con ácido nítrico y separación completa o sustancial del calcio, caracterizado porque el tratamiento con amoniaco se efectúa en tres etapas de neutralización por lo menos, en el cual procedimiento, la temperatura de cada etapa de neutralización es más baja que la temperatura de la etapa precedente, y el líquido de reacción formado se enfría rápidamente entre las etapas de neutralización 2ª y 3ª, con formación de una suspensión.
