Abstract:Abstract:The stainless steel field occupies a dominant position in the nickel consumption structure. With the depletion of nickel sulphide ore and the increase of demand for nickelferrite alloy, laterite nickel ore, as the main raw materials for Nibased alloy production, is usually managed by pyrometallurgical process. However, with the decline of nickel laterite grade and the complication of raw materials characteristics, how to prepare the nickelferrite alloy by green and efficient utilization of lowgrade ore gradually becomes the bottleneck for the sustainable development of stainlesssteel industry in China. According to the research status at home and abroad, and combining with the related work investigated by our group, research development of pyrometallurgical process for laterite nickel ore and its existent insufficiency were explained. Key collaborative techniques of pyrometallurgical process for lowgrade nickel laterite were also developed systematically, which were used to solve the shortage of Nibased raw materials for stainlesssteel production and realize the green and efficient development of stainlesssteel industry.
