ABSTRACT OF DISCLOSURE A method and apparatus for roasting fine grained ores such as cement raw meal, lime, dolomite, gypsum, phos- phate rock and the like. A suspension preheater consisting of a plurality of serially connected cyclone separators is utilized to preheat the raw material. A suspension type roasting furnace follows the suspension preheater which is, depending upon the material being treated, followed by either a rotary kiln for further heat treatment of the material or by a cooler for cooling the product. The apparatus includes an arrangement for recirculating a portion of the material which has passed through the roasting furnace back into the roasting furnace to increase the degree of roasting. An existing preheater, suspension type calciner, rotary kiln cement clinker producing plant can be converted to the method and apparatus by the addition of an appropriately located splash plate.
