Abstract

CARACTERIZADA POR EFECTUARSE MEDIANTE CONTACTO DE LA SOLUCION DE CIANURO ACUOSO CONTENIENDO LOS METALES PRECIOSOS CON UN REACTIVO CONTENIENDO UNA FUNCIONALIDAD DE GUANIDINA. EL REACTIVO DE GUANIDINA EXTRAE EL ORO Y/O PLATA DE LA SOLUCION ACUOSA Y ES LUEGO SEPARADO SUBSECUENTEMENTE DEL REACTIVO DE GUANIDINA Y RECUPERADO MEDIANTE METODOS CONVENCIONALES. EL INVENTO TAMBIEN SE REFIERE A CIERTOS NUEVOS COMPUESTOS DE GUANIDINA QUE SON APROPIADOS PARA EXTRAER ORO A PARTIR DE SOLUCIONES DE CIANURO
