Abstract

Procedimiento para la fabricación de fosfato biamónico mediante la neutralización de ácido fosfórico con amoniaco en un saturador, caracterizado por la separación de fosfato biamónico cristalizado formado de las aguas madres y recirculación de esta agua madres hacia el saturador, y porque se utiliza ácido fosfórico de vía húmeda y se opera sobre la vuelta de las aguas madres hacia el saturador una purga de importancia relativa tal que el grado de impurezas Fe2O3 + Al2O3/P2O5 en las soluciones circulantes no pase de 0,10 aproximadamente.
