Abstract: Recently, the depletion of nickel sulfide resources barely meet the increasing demand and laterite nickel ore gain a special attention as the main source of nickel in the future. Even laterite nickel ore has become a hot spot of research due to its rich reserves, easy mining, and convenient transportation, the effective treatment and efficient utilization of laterite nickel ore is still very appealing. In this article, we mainly introduces the smelting methods and technologies of different laterite nickel ore from different ore layers, summarizes the laterite nickel ore of different ore layers and their applicable smelting processes, analyzes the processing technology of different laterite nickel ore, and realizes different types of laterite comprehensive utilization of nickel ore.
