Nickel Simple English Wikipedia, the free encyclopedia

2020-7-3  Nickel was found when a copper-coloured ore did not make copper metal. Later it was found out that the ore was actually a nickel containing ore. Nickel was isolated as a metal in 1751. At first, the copper colored nickel ore was the only source. Later, it was made as a byproduct of cobalt blue making. Preparation
