摘　　要：伴随新能源行业的快速发展,镍作为能源金属备受关注。高品位硫化镍矿日益减少,如何高效开发和利用红土镍矿再次成为研究的热点。分析了红土镍矿镍铁硫化工艺和富氧侧吹工艺制备高镍锍的应用研究现状,对未来红土镍矿生产高镍锍需注意的问题及未来发展进行了展望。与已产业化的镍铁硫化工艺相比,富氧侧吹工艺使用廉价煤资源,具有原料适应性广、投资强度低、运营成本低等优势。综合来看,该工艺处理红土镍矿生产高镍锍非常有竞争力。富氧侧吹工艺目前在处理红土镍矿方面的应用还处于中试阶段,相较于已工业化的镍铁硫化工艺,该工艺生产高镍锍仍然需要开展大量的工程试验工作。With the rapid development of the new energy industry,nickel has attracted much attention as a critical metal in energy applications.With the decrease of high-grade nickel sulfide ore resources,how to efficiently develop and utilize laterite nickel ore has once again become a research hotspot.This paper analyzes the application and research status of ferronickel vulcanization technology of laterite nickel ore and oxygen-enriched side blowing to prepare high-nickel matte,and shows the problems and future developments in the production of high nickel matte from lateritic nickel ore.Compared with the industrialized ferronickel sulphidizing technology,oxygen-enriched side blowing technology using cheap coal resources owns lots of advantages,such as wide adaptability of raw materials,low investment,low operating costs,and so on.In a word,it is a very competitive processing technology to produce high nickel matte.At present,the application of oxygen-rich side-blowing technology in the treatment of laterite nickel ore is still in the pilot test stage.The production of high nickel matte by oxygen-rich side-blowing technology still requires extensive engineering trials,compared with the industrialized nickel-iron vulcanization process.
