The oxide is obtained from nickel ores by a series of treatments including concentration, roasting and smelting of the minerals. In the first step of the process, nickel oxide is reacted with water gas, a mixture of H 2 and CO, at atmospheric pressure and a temperature of 50 °C. The oxide is thus reduced to impure nickel.
