Carbon monoxide with pressure pCO = 0.01 at 800°C is use to reduce the nickel oxide to metallic nickel.
The chemical symbol is CO.
Nickel can be extracted from it's ore through extractive metallurgy. This entails the process of conventional roasting and reduction processes of nickel ore which will produce nickel metal which is greater than 75% purity. In stainless steel applications, 75% pure nickel can be used without been purified furthe purification which depend the components impurities of impurities present in it. Carbon monoxide is use as the reducing agent as it reduce it from nickel oxide to nickel metal.
Therefore, Carbon monoxide with pressure pCO = 0.01 at 800°C is use to reduce the nickel oxide to metallic nickel.
The chemical symbol is CO.
