ABSTRACT OF THE DISCLOSURE: A process of thermally treating fine-grained solids with high-oxygen gases at temperatures at which the solids form molten and gaseous products, in a cyclone chamber having an axis which is inclined O to 15° from the horizontal. The process is characterized in that the molten product which is separated is discharged through an opening provided in the lower portion of the shell of the cyclone chamber, the gas stream from which most of the molten products have been removed is discharged through an opening, which formed in the end wall and 1. es approximately in the axis of the cyclone chamber into a cooling chamber and is cooled in the cooling chamber in such a manner that molten drop- lets contained the gas stream entering the cooling chamber are cooled below their solidification point as they fly freely. The process of the invention is particularly useful for pyrometallurgi- cal treatmetns, such as the roasting of sulfide ores, ore concentrates and metallurgical intermediate products.
