Overview：Some people were worried about the lack of nickel resources on the earth. Is that true? In recent years, according to the statistics of the International Nickel Association, there are abundant nickel resources on the earth, which can meet the needs of sustainable development of various countries in the world. In terms of quantity, apart from deep-sea reserves, there are about 300 million tons of nickel mineral resources on land alone. At present, the global nickel use is about 2 million tons.
Nickel is one of the most important ternary materials. For nickel resources, some people worried that the earth's nickel resources are very scarce. Is that true?

In recent years, according to the statistics of the International Nickel Association, there are abundant nickel resources on the earth, which can meet the needs of sustainable development of various countries in the world. In terms of quantity, apart from deep-sea reserves, there are about 300 million tons of nickel mineral resources on land alone. At present, the global nickel use is about 2 million tons. Even if the amount of nickel increases by 3% to 5% annually, the existing nickel storage is enough to support the use of the amount. The main nickel deposits on land are laterite nickel and nickel sulfide. Laterite nickel deposits mainly distribute around the equator. At present, the proportion of terrestrial laterite nickel deposits to nickel sulfide is about 6:4. Nickel is distributed in many parts of the world. China and Indonesia are the main storage and production bases of nickel. Laterite nickel ore is mainly used in the manufacture of ferronickel products in China, such as stainless steel.
Nickel is one of the metals that can meet the concept of circular economy. In theory, stainless steel or nickel are 100% non-degradable and recyclable. The quality of waste stainless steel and nickel will not be degraded by recycling. Nickel metal after recycling can also be used again as a very good raw material. It is understood that 82% of nickel metals can be recycled in many countries and regions around the world. At present, the global nickel production is 1.9 million tons per year, while the global nickel use is about 25 million tons. Surface nickel reserves are about 100 million tons, plus about 200 million tons of sub-surface recoverable nickel, a total of 300 million tons. It is not difficult to see that such a high nickel recovery rate and abundant resources reserves can fully meet the high development needs of all countries'industries and the incremental demand for nickel, and meet the requirements of sustainable development.
From the use of nickel, laterite nickel ore is mainly used for sintering and smelting. The initial nickel products are used to produce nickel pig iron, nickel oxide, electronickel, nickel carbonyl and so on. These nickel grade I products are the most widely used in stainless steel manufacturing. The use of nickel in stainless steel accounts for about 68% of global nickel use. In China, 86% of nickel is used in the manufacture of stainless steel. In addition, some alloys and superalloys will be used for nickel. The amount of nickel used in alloy steel and nickel-containing layers is about 9%. Electroplating is also an area where nickel is used in large quantities, with a nickel usage of about 8%. As an emerging industry, new energy batteries are expected to grow considerably in the future, although the current nickel usage is only 3%. Comparatively speaking, the total amount of nickel used in stainless steel is still larger. It is worth noting that China is a big producer of stainless steel, and half of the world's stainless steel is produced in China.
In the terminal market, the application of nickel mainly focuses on transportation, such as automobiles, trains, aircraft and so on. In addition, some electronic products, petrochemical industry, energy engineering equipment and so on will use nickel metal. Nickel is also widely used in the field of green building. At present, many developed countries use nickel-containing stainless steel curtain wall, nickel-containing sunshade system, nickel material interior decoration for the construction industry. Statistical results show that in some large projects, the use of stainless steel containing nickel can reduce the cost of maintenance and other aspects.
