Abstract

Un procedimiento de fabricación de abono fosfocítrico que comprende el ataque del fosfato de cal natural por ácido nítrico mediante concentrado y utilizado sólo o en mezcla con el ácido sulfúrico, el ácido fosfórico o ambos, y después de separar las sales de calcio formadas, o sin separarla la neutralización por el amoniaco del producto resultante del ataque; procedimiento que se caracteriza porque la neutralización se realiza según un círculo contínuo en varias cubas recorridas en serie por la pasta siendo la velocidad de introducción de amoniaco para cada cuba, fijada de una vez para siempre en un valor todo lo próximo posible a la velocidad de absorción la cual tambien es constante para la cuba de que se trata.A process for the manufacture of phosphocitric fertilizer that comprises the attack of natural lime phosphate by nitric acid by means of a concentrate and used alone or in a mixture with sulfuric acid, phosphoric acid or both, and after separating the calcium salts formed, or without the neutralization by ammonia of the product resulting from the attack separates it; This procedure is characterized in that the neutralization is carried out according to a continuous circle in several tanks traversed in series by the paste, the ammonia introduction speed for each tank being fixed once and for all at a value as close as possible to the speed of absorption which is also constant for the tank in question.
