Abstract

TRATAMIENTO DE CONCENTRADOS DE COBRE, QUE PUEDE ESTAR EN FORMA DE SULFURO PRIMARIO, COMO LA CALCOPIRITA, O UN SULFURO SECUNDARIO TAL COMO LA CALCOCINA O COVELINA, PARA OBTENER UN METAL DE COBRE DE ALTA PUREZA, NO MENOR DE 99.99%. EL PROCEDIMIENTO CONSISTE EN: 1) EL MINERAL DE COBRE ES LIXIVIADO CON UNA SOLUCION DE FLUOBORATO FERRICO Y ACIDO FLUOBORICO; 2) FILTRAR LA SOLUCION OBTENIDA EN 1) CON SEPARACION DEL RESIDUO INSOLUBLE CONTENIENDO EL AZUFRE ELEMENTAL; 3) SOMETER LA SOLUCION FILTRADA A ELECTROEXTRACCION EN UNA CELDA DE DIAFRAGMA OBTENIENDO EL COBRE DE ALTA PUREZA EN EL CATODO DE LA CELDA
