Beschreibung
Zusammenfassung:	The invention relates to a method and apparatus for raising the temperature and mixing efficiency of mainly non-combustible pulverous solid particles so high, that a desired smelting and volatilizing is achieved. The method is characterized in that the heating and mixing are carried out in at least two stages. Advantageously the reactions are made to happen in a suspension smelting furnace, such as a flash smelting furnace.
