How Is Nickel Extracted? Reference.com

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.

Nickel Metal: It''s Properties, History, Production & Uses

Jul 14, 2019 · The Mond (or Carbonyl) Process is the most common and efficient method to treat nickel sulfide. In this process, the sulfide is treated with hydrogen and fed into a volatilization kiln. Here it meets carbon monoxide at about 140F° (60C°) to form nickel carbonyl gas. The nickel carbonyl gas decomposes on the surface of preheated nickel

The Mond process, sometimes known as the carbonyl process, is a technique created by Ludwig Mond in 1890, to extract and purify nickel.The process was used commercially before the end of the 19th century. This process converts nickel oxides into pure nickel. This process involves the fact that carbon monoxide combines with nickel readily and reversibly to give nickel carbonyl.
