Flett and Melling . Another method of separation of copper and nickel has been proposed by Giannopoulou and Panias by electro recovery of copper followed by nickel precipitation through neutralization. In this work separation of copper and nickel is carried by selective extraction of copper and nickel at different pH followed by the

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
Nickel is also readily recycled from many of its applications, and large tonnages of secondary or scrap nickel are used to supplement newly mined metal. Only about 1.4 million tonnes of new or primary nickel are produced and used annually in the world, compared with over 10 million tonnes of copper and nearly 800 million tonnes of steel.
