Abstract

"Procedimiento para la recuperación y separación de metales preciosos de convertidores catalíticos''.El objetivo de la presente invención es proporcionar un nuevo método de recuperación y separación de los metales del grupo de platino de diferentes tipos de catalizadores, especialmente de los convertidores catalíticos empleados en automoción, caracterizado porque conlleva la lixiviación de dichos metales preciosos del grupo del platino por procesos de cianuración a alta temperatura y una posterior separación de los metales del grupo del platino (platino, paladio y rodio) mediante carbono activo y precipitación térmica selectiva."Procedure for the recovery and separation of precious metals from catalytic converters." The aim of the present invention is to provide a new method of recovery and separation of platinum group metals from different types of catalysts, especially of the catalytic converters employed. in automotive, characterized in that it involves the leaching of said precious metals of the platinum group by high temperature cyanidation processes and a subsequent separation of the platinum group metals (platinum, palladium and rhodium) by active carbon and selective thermal precipitation.
