Nickel is a naturally-occurring metallic element with a silvery-white, shiny appearance. It is the fifth-most common element on earth and occurs extensively in the earth’s crust and core. Nickel, along with iron, is also a common element in meteorites and can even be found in small quantities in plants, animals and seawater.
While the concentration of nickel in the earth's crust is 80 parts per million, the earth's core consists mainly of a nickel-iron alloy
Nickel has outstanding physical and chemical properties, which make it essential in hundreds of thousands of products. Its biggest use is in alloying - particularly with chromium and other metals to produce stainless and heat-resisting steels.
The terms “reserves” and “resources” are used to describe the availability of raw materials. The Committee for Mineral Reserves International Reporting Standards defines the terms as follows: “A mineral resource is a concentration or occurrence of solid material of economic interest in or on the Earth’s crust in such form, grade or quality and quantity that there are reasonable prospects for eventual economic extraction. A mineral reserve is the economically mineable part of a Measured and/or Indicated Mineral Resource.”
‘Reserves’ imply an increased level of knowledge and confidence. Mining companies continuously convert resources into reserves by exploration. In most cases therefore, limitations in the availability of raw materials are less an issue of whether there is enough raw material in the ground, than whether there is enough production capacity available in a short time frame to satisfy a sharp increase in demand.
The world’s nickel resources are currently estimated at almost 300 million tons.
Australia, Indonesia, South Africa, Russia and Canada account for more than 50% of the global nickel resources. Economic concentrations of nickel occur in sulphide and in laterite-type ore deposits.
Despite the fact that nearly 80% of all nickel historically mined was extracted over the past three decades, known nickel reserves and resources have also steadily grown. Various parameters play a role in this evolution, including better knowledge of new deposits in remote areas and increased exploration activities by mining companies, driven by attractive commodity prices. Improved technologies in mining, smelting and refining, as well as increased capacities, also allow for lower-grade nickel ore to be processed. Decreasing ore grades are therefore not necessarily a sign of diminishing resources, but a reflection of innovation and improvements made in mining and process technology.
There are also reckoned to be significant nickel deposits in the deep sea. Manganese nodules, which are found on the deep-sea floor, contain significant amounts of nickel. Recent estimates indicate more than 290 million tons of nickel contained in such deposits. The development of deep-sea mining technologies is expected to facilitate access to these resources in future.

Nickel occurs naturally, principally as oxides, sulphides and silicates. Primary nickel is produced and used as ferro-nickel, nickel oxides and other chemicals, and as more or less pure nickel metal. Over two million tonnes of new or primary nickel are produced and used annually in the world.
There are many different nickel ores requiring a variety of techniques to extract the nickel.
Nickel-containing ores are currently mined in more than 25 countries worldwide.

'First use' of nickel is defined as the conversion of nickel products into intermediate products, which form the basis for nickel-containing end-use products. In almost all cases, these first-use products undergo further processing before they are ready for use.
Due to its outstanding physical and mechanical properties, nickel is used in a wide range of end-use sectors.
Socio-economic data on nickel show the importance of industries throughout the nickel value chain, from mining through end use to recycling. The data quantify important metrics, such as employment or value added. They also serve as the basis for modelling the positive and negative impacts of, for example, market developments or regulatory initiatives. In cooperation with Roskill, the Nickel Institute collects and updates socio-economic data for the main nickel producing and using countries.
In Europe, a socio-economic assessment was done for 12 of the most relevant economies where significant nickel production or use occurs. In these countries, the total value added by the nickel industry and its value chains is estimated to be €43 billion. In addition, the output generated by nickel and related industries is around €130 billion, implicating around 750,000 jobs which depend directly or indirectly on nickel (reference year 2017).
Globally, the nickel value chain supports large numbers of jobs, many of which are high skill manufacturing occupations.

Society cares more and more about sustainability and needs to know more about the materials that contribute to a sustainable future. Nickel is one of those materials.
Nickel is an element. It cannot be created nor destroyed. Its attributes - corrosion resistance, high-temperature stability, strength, ductility, toughness, recyclability, as well as catalytic and electromagnetic properties help achieve sustainability. Nickel in its various forms is often unseen, yet it plays hundreds of roles in thousands of products and applications we use every day.
While its role is often hidden, nickel is an enabler of many technologies required for sustainability. Nickel contributes to the achievement of many of the UN Sustainable Development Goals (SDGs), in lots of ways.
Nickel is a natural resource, which cannot be consumed. Like many other metals, nickel is fully recyclable. It can be recycled again and again without loss of quality, contributing to the Circular Economy (CE) model.
As nickel-containing products have value, there is an infrastructure for gathering and processing them. Gathering, sorting, preparing, transporting and using scrap metal generates significant employment and adds economic value.
