Nickel oxideThe raw material of sintered nickel oxide is nickel laterite, and the basic process flow is as follows: 90% of the ore with particle size less than 74m is placed in a multi chamber furnace for reduction roasting.
Nickel saltSo far, nickel salts that can be produced on a large scale and widely used are mainly nickel sulfate and nickel chloride. They are mainly used in the nickel plating industry.
The nickel products in China are relatively simple, mainly electrolytic nickel, and the output of nickel oxide and nickel iron is very small. The price of electrolytic nickel is extremely expensive, which weakens its competitiveness in the stainless steel market.
In recent years, the strong demand for stainless steel has stimulated the demand for nickel metal, which has led to the continuous high price of nickel.
After hundreds of years of development, carbonyl method has formed three production processes under normal pressure, medium pressure and high pressure.
The industrial production of nickel carbonyl appeared at the beginning of the 20th century. After more than 100 years of development, both industrialization and product development have been very perfect.
