    Abstract: According to a method for utilising solid, optionally with the addition of iron ore, the recyclings are introduced into a melting cyclone (6), together with a reduction agent containing carbon, and oxygen, swirled and ignited. The recyclings are melted, the volatile heavy metals are reduced and evaporated and the iron oxides are reduced. The gases and melt are transferred together from the melting cyclone (6) to a directly connected separating vessel (7) in which the melt and gases are separated. The evaporated heavy metals are separated out of the gases outside of the separating vessel (7) and the melt is transferred into a metallurgical vessel (10) that is separate from the separating vessel (7). According to the invention, reduction agents which are fed into the metallurgical vessel (10) reduce the iron oxides of the melt to iron, whereby a slag that is low in iron is formed, while electrical energy is introduced to at least partially cover the heat loss and the reduction energy, in order to transform 100 % of the recyclings containing iron and heavy metals into useful products.
