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 (), 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 (). By means of the method, the recovery of metals is facilitated. An apparatus for performing the method is also provided.

Method and an apparatus for recovery of metals

A method for treatment of sludge is disclosed, wherein the sludge has a liquid part and metal-containing particles intermixed therein. The particles comprise metal, metal oxide or metal hydroxide and the method comprises the following steps: atomising the sludge; supplying the atomised sludge to a flame of a burner provided in a furnace; bringing the liquid part of the sludge to vaporize by means of the flame while maintaining said flame by means of a separate fuel supply; and bringing at least part of the metal-containing particles to melt by means of the flame. This provides an efficient method for taking care of waste material from plants in the steel or petrochemical industry, for example.
