Abstract

DONDE EL AGENTE TENSIOACTIVO NO IONICO, EN UNA CONCENTRACION DE 0,01 A 0,2% EN PESO EN UNA SOLUCION ACUOSA AJUSTADA A UN pH DE 9,8 A 10,2 CON NaOH, A 23°C CONDUCE A UNA REDUCCION EN EL ANGULO DE CONTACTO EN EL VIDRIO DESPUES DE 1s ENTRE 10° Y 40°. DICHO AGENTE ES SELECCIONADO DE ALCOXILATOS DE ALCOHOL, ALCOXILATOS DE ALQUILFENOL, ALQUILPOLIGLUCOSIDOS, COPOLIMEROS EN BLOQUE DE OXIDO DE ETILENO, OXIDO DE PROPILENO Y/O OXIDO DE BUTILENO, DERIVADOS DE ANHIDRIDO POLIISOBUTENO/MALEICO, GLICERIDOS DE ACIDO GRASO, ESTERES SORBITAN, BISGLICERIDOS, ENTRE OTROS. LA COMPOSICION ADICIONALMENTE COMPRENDE POR LO MENOS UN AGENTE TENSIOACTIVO CATIONICO Y/O POR LO MENOS UN AGENTE TENSIOACTIVO ANIONICO. LA COMPOSICION SE PONE EN CONTACTO CON MATERIALES QUE CONTIENEN METALES OPCIONALMENTE MOLIDOS, EN PRESENCIA DE UN AGENTE OXIDANTE, PARA OBTENER UN LICOR MADRE ENRIQUECIDO CON COMPLEJOS CIANURO METAL, SIENDO SEPARADO EL COMPLEJO DE METAL Y REDUCIDO EL METAL DEL COMPLEJO PARA OBTENER EL METAL ELEMENTAL. EL METAL ES ORO, PLATA Y/O PLATINO, Y LOS MATERIALES QUE CONTIENEN ORO SE SELECCIONAN DE CUARZO QUE CONTIENE ORO, PIRITAS QUE CONTIENEN ORO, SILVANITA, NAGIAGITA Y CALVAITA; Y LOS QUE CONTIENEN PLATA SE SELECCIONAN DE PLATA AGRIA, ESTROMEYERITA Y SULFURO DE PLATA DOBLES CON SULFURO DE ARSENICO Y SULFURO DE ANTIMONIO
