Abstract

Método de fabricación de productos fosfo-ureicos. Consistente en la molienda y posteriormente mezcla de fosfato roca mineral y urea y opcionalmente sulfato cálcico, utilizando en ambos casos mezcladores y molinos convencionales, atacándose la mezcla obtenida mediante un compuesto ácido que preferiblemente será ácido sulfúrico diluido. Se utilizan 12,24 moles de [H{sup,+}] por cada kilogramo de fosfato roca mineral. La granulometría de la mezcla fosfato mineral-urea-sulfato ácido será < 120{mi} para el 85% y el grado de disolución acuosa del compuesto ácido estará comprendido entre el 65-75% efectuándose el ataque a la temperatura más conveniente de 75ºC.Method of manufacturing phospho-ureic products. Consisting of the grinding and subsequently mixing of mineral rock phosphate and urea and optionally calcium sulfate, using in both cases conventional mixers and mills, the mixture obtained is attacked by an acid compound that will preferably be diluted sulfuric acid. 12.24 moles of [H {sup, +}] are used per kilogram of mineral rock phosphate. The granulometry of the mineral phosphate-urea-sulfate acid mixture will be <120 {mi} for 85% and the degree of aqueous solution of the acidic compound will be between 65-75% with the attack at the most convenient temperature of 75 ° C.
