Abstract

QUE COMPRENDE: a) FORMAR UNA SOLUCION ACIDA DILUIDA DEL MATERIAL CONTENIENDO EL METAL VALIOSO Y ARSENICO; b) SEPARAR POR LO MENOS UN METAL VALIOSO DE LA SOLUCION POR EXTRACCION LIQUIDO-LIQUIDO Y/O PRECIPITACION; c) SEPARAR EL ARSENICO DE LA SOLUCION DESPROVISTA DEL METAL VALIOSO EN DOS ETAPAS: LA PRIMERA DONDE EL ARSENICO SE PRECIPITA EN FORMA DE ESCORADITA (FeAsO4.2H2O) REGULANDO EL pH ENTRE 1 Y 2 CON PIEDRA CALIZA O CAL, LA TEMPERATURA ENTRE 85°C Y 135°C Y LA PROPORCION MOLECULAR Fe/As ENTRE 1-1.1, Y LA SEGUNDA DONDE EL ARSENICO DE LA SOLUCION QUE SALE DE LA PRECIPITACION ES PRECIPITADO EN FORMA DE ARSENIATO FERRICO AMORFO (FeAsO4) EL CUAL ES RECICLADO A LA PRIMERA ETAPA, SIENDO LA CONCENTRACION DE As DE LA SOLUCION ACUOSA QUE SALE DE LA SEGUNDA ETAPA ENTRE 0,01-0,2 mg/L. EL MATERIAL A SER TRATADO ES CENIZA O CALCINA GENERADAS EN LA FABRICACION PIRO-METALURGICA DE METALES NO FERROSOS. POR LO MENOS PARTE DEL ACIDO DILUIDO EMPLEADO PARA LA LIXIVIACION DEL MATERIAL QUE CONTIENE UN METAL VALIOSO Y ARSENICO, ES ACIDO SULFURICO CON UNA CONCENTRACION DE 10 A 200 g/L CONTENIENDO ARSENICO GENERADO EN EL TRATAMIENDO DE GASES QUE LO CONTIENEN. EL METAL VALIOSO ES COBRE
