Abstract

LA PRESENTE INVENCION ESTA RELACIONADA CON UN PROCESO DE TRATAMIENTO DE AGUAS RESIDUALES QUE CONTIENEN TALIO, PROCEDENTES ESPECIALMENTE DE LA LIXIVIACION POR OXIDACION DE LOS POLVOS FINOS RESULTANTES DEL PROCESADO METALURGICO DE MINERALES SULFUROSOS, Y DE METALES COMO ZINC, PLOMO, CADMIO, COBRE, ARSENICO, SELENIO Y TELURIO. EL PROCESO INCLUYE LA ADICION AL EFLUENTE DE UNA SOLUCION DE CARBONATO ALCALINO Y CAUSTICOS ALCALINOS PARA OBTENER LA PRECIPITACION POR NEUTRALIZACION DE LOS METALES ZINC, PLOMO, CADMIO, COBRE, ARSENICO, SELENIO Y TELURIO. A CONTINUACION SE AÑADE UNA SOLUCION SULFUROSA PARA PRECIPITAR EL TALIO Y EL PRECIPITADO OBTENIDO SE SEPARA INMEDIATAMENTE DEL AGUA RESIDUAL.
