The history of nickel
Nickel plays an important role in the development of human material civilization. Because the melting points of nickel and iron are close, nickel was mistaken for good iron by ancients. In ancient times, Chinese, Egyptians and Babylonians used meteorite iron with high nickel content to make utensils, and because nickel did not rust, it was also regarded as silver by the Peruvian indigenous people. As early as 235 BC, my country began to use nickel minerals to make coins, and cupronickel, or copper-nickel alloy, was invented and used by our ancients in 200 BC. In 1751, Alex Fredrik Cronstedt of Stockholm studied a new metal called NiAs (NiAs). He thought it contained copper, but what he extracted was a new metal, which was announced in 1754 and named nickel (nickel).
During the extraction process, the metal cobalt, arsenic and copper alloys appeared as trace contaminants, which were misunderstood by many chemists. It was not until 1775 that pure nickel was produced by Torbern Bergman, which confirmed that it is an element. . In 1952, there was a report that nickel was found in animals, and later it was suggested that nickel is an essential trace element for mammals. After 1975, research on the nutrition and metabolism of nickel was carried out.
Nickel industry development
In recent years, the world's nickel production and consumption have been relatively stable. The supply and demand situation of the world's nickel market mainly changes with the development of the stainless steel industry. With the growth of nickel in the consumption of the stainless steel industry, the nickel-iron smelting technology has made great progress. , The output of high-grade ferronickel has been greatly increased. The major countries with nickel ore resources are mainly Russia, Canada, New Caledonia, Indonesia, Australia and Cuba. The combined mineral nickel production and exports account for about 80% of the world's total.
Nickel smelting is mainly concentrated in Russia, Japan, Canada, Australia, Norway, China, New Caledonia, the United Kingdom, South Africa and Finland.
The main nickel consuming countries are also the main producers of stainless steel, including Japan, the United States, Germany, Russia, Italy, France and South Korea. Among the major nickel consuming countries, only Russia is a nickel resource country. The remaining consuming countries have almost no nickel ore available for mining, mainly relying on imported nickel concentrates and other primary nickel products. With the continuous consumption of nickel resources and the continuous reduction of resource reserves, finding and rationally mining new nickel mines and increasing the development of nickel resource recycling industries have become important tasks for the development of the current nickel industry.
my country is currently the world’s largest producer and consumer of ferronickel. With the continuous development of the economy and steel industry, the demand for nickel resources continues to increase. At the same time, the output of nickel ore is also increasing, which has gradually resulted in the current global nickel The severe pattern of oversupply in the city. In domestic stainless steel production, ferronickel is used as a raw material for production, and the proportion of its use will increase year by year, and the use of pure nickel is showing a downward trend. With the continuous development of my country’s nickel industry, problems have also followed. For example, nickel mines are mostly low-grade, the proportion of open mining is small, the recoverable reserves are relatively small, and the mining and smelting technology is relatively backward, which is in line with the world’s advanced technology. There is still a big gap, and the cost of mining and smelting remains high. It can be seen that my country’s nickel industry still has a lot of room for development.
