A method for recovery of metals from essentially metallic fines comprises the following steps: supplying said essentially metallic fines to a flame of a burner (20), bringing said fines to agglomerate by means of heat from the flame without essentially changing the chemical composition thereof, thereby providing an essentially metallic agglomerated product. The agglomerated product is subsequently recovered, preferably in a furnace (30). By means of the method, the recovery of metals is facilitated. An apparatus for performing the method is also provided.
L'invention concerne un procédé de récupération de métaux à partir de fines particules métalliques, consistant à amener lesdites particules métalliques vers la flamme d'un brûleur (20), à obtenir l'agglomération de ces particules sous l'effet de la chaleur de la flamme sans changement sensible de leur composition chimique, obtenant ainsi un produit aggloméré essentiellement métallique. Ce produit aggloméré est ensuite récupéré, de préférence dans un four (30). Le procédé de l'invention permet de simplifier la récupération de métaux. L'invention concerne également un dispositif servant à mettre en oeuvre ce procédé.
