ABSTRACT:
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.
