Abstract

Metallic ores are directly reduced by feeding the ore into a hot rotary kiln with suitable fluxes, introducing and controlling the flow and direction of oxidising gas to the kiln, and feeding high volatile carbonaceous solids into both ends of the kiln without introducing the feed propellant gas. Appts. comprises a rotary kiln, inlet hopper, discharge chute, directional oxidising gas tuyeres, and carbonaceous material feed inlet boxes with air extraction. The kiln has a length to diameter ratio of between 20 and 35.
