ABSTRACT OF THE DISCLOSURE: A process of thermally treating fine-grained solids with high-oxygen gases and, if desired, energy carriers at temperatures at which said solids form molten and gaseous products, in which process the solids, high-oxygen gases and any energy carriers are mixed to form a suspension at a temperature below the reaction temperature and, as said suspension, are fed into a vertical combustion path at a velocity which precludes back-firing and are reacted in the combustion path to form a suspension which contains mainly molten particles, and the latter suspension is fed into a cyclone chamber. The process of the invention is character- ized in that the molten material produced from the suspension is separated in the cyclone chamber and discharged through an opening provided in the lower portion of the shell of the cyclone, the gas stream from which most of the molten products have been removed is discharged through an opening, which is formed in the end wall and lies approximately in the axis of the cyclone chamber, into a cooling chamber, which directly follows in the direction of flow, and reactants are added to the gas phase to initiate a subsequent reaction within the core flow region of the cyclone chamber and/or immediately after the discharge of the gases from the cyclone chamber.
