What is Nickel?

Nickel is a silvery-white metal that is used mainly to make stainless steel and other alloys stronger and better able to withstand extreme temperatures and corrosive environments. Nickel was first identified as a unique element in 1751 by Baron Axel Fredrik Cronstedt, a Swedish mineralogist and chemist. He originally called the element kupfernickel because it was found in rock that looked like copper (kupfer) ore and because miners thought that "bad spirits" (nickel) in the rock were making it difficult for them to extract copper from it.

Nickel is an essential trace element for some animals. Some people are sensitive to nickel and may develop contact dermatitis if their skin comes in close contact with it. Although many nickel alloys, including stainless steel, do not cause health problems, special precautions must be taken to ensure the safety of those working with certain other nickel compounds and even metallic nickel because they have been known to cause cancer.

How Do We Use Nickel?

Approximately 80 percent of the primary (not recycled) nickel consumed in the United States in 2011 was used in alloys, such as stainless steel and superalloys. Because nickel increases an alloy's resistance to corrosion and its ability to withstand extreme temperatures, equipment and parts made of nickel-bearing alloys are often used in harsh environments, such as those in chemical plants, petroleum refineries, jet engines, power generation facilities, and offshore installations. Medical equipment, cookware, and cutlery are often made of stainless steel because it is easy to clean and sterilize.

All U.S. circulating coins except the penny are made of alloys that contain nickel. Nickel alloys are increasingly being used in making rechargeable batteries for portable computers, power tools, and hybrid and electric vehicles. Nickel is also plated onto such items as bathroom fixtures to reduce corrosion and provide an attractive finish.

Where Does Nickel Come From?

Nickel is the fifth most abundant element in the Earth, but most of that nickel is located in the core, more than 1,800 miles below the surface. In Earth's crust, two major types of ore deposits supply most of the nickel used today: magmatic sulfide deposits (such as the pentlandite and pyrrhotite deposits found at Norilsk, Russia; Sudbury, Ontario, Canada; and Kambalda, Australia) and laterite deposits (including those found in Cuba, New Caledonia, and Indonesia). Also, manganese nodules and crusts on the deep sea floor may contain as much nickel as the deposits known onshore, but they are not currently being mined.

Magmatic sulfide deposits contain about 40 percent of global nickel resources and currently are the source of more than one-half of the world's nickel supply. Nickel deposits may develop if magma that contains low amounts of silica and high amounts of magnesium becomes saturated in sulfur, usually through reacting with rocks in Earth's crust. A sulfur-rich liquid may separate from the magma; ions of nickel, and some other elements, may move into it. Because the sulfur-rich liquid is denser than the magma, the liquid sinks and accumulates along the base of magma chambers, intrusions, or lava flows, where nickel-bearing sulfide minerals may then crystallize. The sulfide minerals often contain cobalt, copper, or platinum-group metals as well.

The Sudbury Igneous Complex is Canada's leading source of nickel and the second largest nickel sulfide deposit in the world. The complex is unique because it was formed when an extraterrestrial body, likely an asteroid or comet, hit Earth about 1,850 million years ago. Parts of Earth's crust near the impact melted and formed a large layer of magma in the resulting crater; nickel-bearing sulfide liquid collected along the base of the magma layer, and nickel- and copper-bearing sulfide minerals crystallized from it.

Laterite deposits host approximately 60 percent of the world's nickel resources. Laterite deposits form in warm, humid, tropical or subtropical environments when igneous rocks with low amounts of silica and high amounts of magnesium are broken down by chemical weathering. Weathering removes some of the original rock components, creating residual deposits where elements such as nickel may be concentrated.

Earth's nickel core

Nickel: Worldwide Supply and Demand

New Caledonia131,000
South Africa44,000
United States0
Other Countries103,000
The values above are 2011 metric tons of nickel content production from USGS Mineral Commodity Summaries, January 2013.

There were no active nickel mines in the United States in 2011, although small amounts of nickel were recovered as a byproduct from processing copper and palladium-platinum ores. Several deposits in Minnesota and Michigan have potential for development.

Recycled nickel is an extremely important source of supply. In 2011, recycled nickel accounted for approximately 43 percent of U.S. nickel consumption.

Russia was the leading producer of nickel in 2011, followed by Indonesia, the Philippines, and Canada. From 2007 through 2010, Canada supplied approximately 38 percent of U.S. nickel imports followed by, in order of the amount imported, Russia (17 percent), Australia, Norway, and other countries. The bulk of the world's known nickel reserves are concentrated in Australia, Brazil, Canada, Cuba, New Caledonia, and Russia.

Ensure Future Nickel Supplies

The United States relies on imports and recycling for its supplies of nickel, and this situation is unlikely to change significantly for at least the next 25 years. The risk of a disruption in supply is low, however, because there are sufficient global reserves, spread across more than 10 countries, to meet projected demand for nickel for many years to come. The U.S. Government no longer holds nickel in the National Defense Stockpile. Production from laterite deposits is likely to increase as the nickel resources in existing sulfide mines are depleted.

To help predict where future nickel supplies might be located, USGS scientists study how and where nickel resources are concentrated in Earth's crust and use that knowledge to assess the likelihood that undiscovered nickel deposits may exist. Techniques to assess mineral resources have been developed by the USGS to support the stewardship of Federal lands and to evaluate mineral resource availability in a global context. The USGS also compiles statistics and information on the worldwide supply of, demand for, and flow of nickel. These data are used to inform U.S. national policymaking.
