Abstract
PROCEDIMIENTO PARA SEPARAR SIMULTANEAMENTE CASCARILLAS DE HIERRO Y COBRE DE UNA SUPERFICIE METALICA FERREA.CONSISTE EN: A) PONER EN CONTACTO, A LA SUPERFICIE METALICA FERREA CONTENIENDO CASCARILLA CON UNA COMPOSICION DE 1 A 10 EN PESO DE UN ACIDO DE QUELACION ORGANICO O MEZCLA DE ACIDOS DE QUELACION ORGANICOS; 0,25 A 5 EN PESO DE UN AGENTE REDUCTOR QUE AUMENTA LA VELOCIDAD DE DISOLUCION DE HIERRO POR EL ACIDO O ACIDOS DE QUELACION ORGANICOS; DE 0,25 A 3 EN PESO DE UN COMPUESTO COMPLEJANTE DE COBRE Y SIENDO EL RESTO AGUA, A UNA TEMPERATURA DE 60JC; Y B) MANTENER EL CONTACTO DURANTE UN TIEMPO Y A UNA TEMPERATURA SUFICIENTE PARA QUE SE DISUELVAN LAS CASCARILLAS. EL ACIDO DE QUELACION ORGANICO O LA MEZCLA DE ACIDOS DE QUELACION ORGANICO, SE ELIGEN ENTRE EL ACIDO HIDROXIACETICO, ACIDO ACETICO, ACIDO FORNICO Y OTROS. EL AGENTE REDUCTOR SE ELIGE ENTRE ACIDO ERIFORBICO, SALES DE METAL ALCALINO DE ACIDO ERIFORBICO. EL COMPUESTO COMPLEJANTE SE ELIGE ENTRE TIOUREA, HEXAHIDROPIRIMIDINA-2-TIONA Y MEZCLAS DE LOS MISMOS.
