Abstract

LA CHATARRA DE COBRE, REDUCIDA A FORMA TRITURADA CON TAMAÑOS DE PARTICULAS NO SUPERIORES A 50 MM., SE LIXIVIA EN UN APARATO APROPIADO CON UNA DISOLUCION DE FLUOROBORATO FERICO EN ACIDO FLUOBORICO. DURANTE EL LIXIVIADO SE DISUELVE EL COBRE, CON REDUCCION SIMULTANEA DEL FLUOROBORATO FERICO A FLUOROBORATO FERROSO SEGUN LA SIGUIENTE REACCION: 2 FE (BF4)3 + CU --> CU (BF4)2 + FE (BF4)2 LA DISOLUCION RESULTANTE SE COLOCA EN EL COMPARTIMIENTO CATODICO DE UNA CELULA E DIAFRAGMA EN LA CUAL SE DEPOSITA EL COBRE, EN FORMA COMPACTA Y DE GRAN PUREZA, SOBRE UN CATODO DE ACERO INOXIDABLE DEL CUAL SE RECUPERA PERIODICAMENTE.
