To seek for the optimum condition for fluidizing reduction, many tests were tried in a 100 mm dia. reactor which was heated by electric heater. Each test was contineous feeding operation within 60∿70h. Considered factors were height of overflow pipe, gas flowing volume, holding time, temperature etc. It was concluded that the optimum condition can attain 1.5 as gas excess ratio. With these data, a semi-pilot plant is discussed. Triple hearth furnace are recommended. Efforts must be added in a semipilot plant to develop next unknown technique. 1. Start-up of the triple hearth fluidizing reactor. 2. Steady operation of the triple hearth reactor. 3. Production of hot gas. 4. Heating up of ore by surface combustion.
