  • How Is Nickel Extracted? Reference

    A Nickel is extracted from ores via the Mond process, in which nickel oxides are purified through multiple steps into pure nickel metal. It is placed with hydrogen and carbon monoxide gases at 122 degrees Fahrenheit, which converts it to impure nickel. This impure nickel then reacts with the carbon monoxide, becoming nickel tetracarbonyl.
