carbothermic reduction method, leaving an iron rich residue. Thus, many investigations had been conducted on the kinetics of the reduction reaction of zinc oxide with –10) The reaction of zinc oxide with carbon can be expressed as: ZnO(s) þ C(s) ¼ Zn(g)þ CO(g) ð1Þ This reaction is a combination of the following reactions:
The reduction specimens were spheres ranging in size from to diameter and by bars either or cm. thick. They were prepared from electrolytic iron powder, partially oxidized in a rotary kiln. The final oxidation of the specimens to hematite was accomplished by firing them at 1,149°C. in an oxidizing atmosphere.
