Abstract
312,667. Folliet, A., and Sainderichin, N. May 30, 1928, [Convention date]. Rotary furnaces.-In the reduction of volatile metals such as zinc, the ore is charged from a hopper 2 into one end of a rotary furnace 1, and highly heated air is admitted to the other end from a pipe 3 provided with tangential nozzles 3<1>. Coal is fed from a hopper 4. The vapours evolved pass to a condenser 6 and residues are discharged at 5.
