Abstract:Based on analysis of new energy vehicle development status and the current demand for nickel and cobalt resource, the principle, technical indexes and technical feature of the process of limonite laterite nickel ore resource utilization were analyzed. Limitations of current methods and key technical problems to be solved in resource utilization of limonite laterite nickel ore were discussed. New trend of its resource utilization was pointed out, and research status and main problems of new technology for separation nickel from iron were given.
