Abstract

EL INVENTO SE REFIERE A UN PROCEDIMIENTO HIDROMETALURGICO DE DESCONTAMINACION DE LAS TIERRAS CONTAMINADAS (I) POR ELEMENTOS METALICOS QUE COMPRENDE UNA ETAPA DE LIXIVIACION BASICA (I) DE MANERA QUE SE PROVOCA LA DISOLUCION DE LOS ELEMENTOS METALICOS QUE HAY QUE ELIMINAR, UNA ETAPA DE CEMENTACION (II) QUE PROVOCA LA PRECIPITACION (6) DE DICHOS ELEMENTOS EN FORMA DE METAL, EFECTUADA POR INTERCAMBIO ELECTROQUIMICO CON UN POLVO DE ZINC (5) PRODUCIDO POR UNA ETAPA DE ELECTROLISIS (III) DE LA SOLUCION (7) PRODUCTO DE LA ETAPA DE CEMENTACION (II). SEGUN EL INVENTO, SE REALIZA UN APORTE COMPLEMENTARIO DE ZINC, PREFERENTEMENTE AL FINAL DE LA ETAPA DE LIXIVIACION, EN FORMA DE UNA LIXIVIACION (17) DE DESECHOS SIDERURGICOS, EN PARTICULAR DE POLVOS (13) DE ACERIA ELECTRICA (15).
