<p>A method and an apparatus for recovering platinum group metals from a metal catalyst are disclosed, in order to separate the substrate containing the metal catalyst from the carrier, the sheets of the catalyst package are unwound. The sheets are then crushed by feeding them through the gap of a pair of rollers. Also disclosed are a method and an apparatus for wet separating the carrier from the substrate after a first separation has been made. The carrier and substrate particles, containing metal catalyst, are brought in rubbing contact. The coarse and fine particles are separated from one another. The fine particles are further treated for recovery of the metal catalyst.</p> |
