Some facts
Nickel is an alloy metal used in many industrial and consumer products, including stainless steel, magnets, glass, special alloys such as nickel brasses and bronzes, and alloys with copper, chromium, aluminium, lead, cobalt, silver and gold. 60% of global Nickel consumption is for nickel steels with alloys and plating comprising a further 25% of consumption.

Canada produces about 30 percent of the world's supply of nickel form the Sudbury Basin deposit. This deposit is thought to have been created by a massive meteorite impact event early in the geologic history of Earth. Russia contains about 40% of the world's known resources at the Norilsk deposit in Siberia. Other major deposits of nickel are found in New Caledonia, Australia, Cuba, and Indonesia.
