Ni powders were prepared in various gases form commercial NiO ores at different reaction conditions. Nickel oxide (NiO) pellet mixed with carbon powders was reduction in N₂gases at first reductive stage. In the temperature range from 800 to 1000℃, the reduction rate of NiO increased with increasing temperature, reaction time, and carbon content in the pellet. At second stage NiO was consecutively reduced by hydrogen (H₂)and the rate of reduction time, hydrogen content. It was finally found that NiO was found to be almost completely reduced by hydrogen with 1.0m³/hr at 1000℃ for 1 hour.
