Nickel is an important nonferrous metal with a wide range of uses. It mainly occurs in nickel sulfide and nickel oxide ores in nature. 30% of nickel resources are sulfide ores and 70% are laterite nickel ores. With the increasing demand for nickel and the gradual depletion of nickel sulfide ore, the development of laterite nickel ore shows a vigorous trend.
