Aug 5, 2017 . Most of the nickel we use on Earth is mined from a number of nickel ores: pentlandite and pyrrhotite (iron nickel sulfides, the two most important nickel ores), . (where the ore is split into its constituents by passing an electric current through a solution), or by reacting it with acids (in the Mond process).

Nickel - Rock Files - Australian Mines Atlas

Nickel is not as well known as other metals, but it plays an important, if invisible role in modern life. It has some very useful properties, and when it is mixed with other metals it helps create amazing alloys that are strong, won't rust, can withstand high and low temperatures, and can be easily shaped into anything from thin.
