摘要
分析了全球镍钴资源分布状况,归纳总结了镍钴冶炼技术现状。近年来,新发现的大型硫化镍钴矿较少,红土镍矿冶炼技术进步比硫化镍矿要快,特别是回转窑—电炉(RKEF)生产镍铁技术和高温高压浸出技术(HPAL)得到推广应用以来,红土镍矿获得大规模开发利用。钴产量主要来源于铜钴矿和红土镍矿湿法冶炼副产的钴,铜钴分离和镍钴富集技术也已得到广泛应用。最后对我国镍钴冶炼技术未来发展趋势进行了预测。
The status of nickel and cobalt resources and extraction technologies were summarized.In recent years,there are few newly discovered large nickel and cobalt sulfide deposits.The development of technologies for extraction of nickel laterite ore is much faster than that of nickel sulfide ore,especially with the application of rotary kiln-electric furnace(RKEF)technology and high temperature and high pressure leaching technology(HPAL),nickel laterite ore has been widely exploited.The production of cobalt mainly comes from Cu-Co ore and nickel laterite hydrometallurgy byproduct.Technologies for separation of Cu/Co and Ni/Co have been widely used in the world.Finally,the future development trend of nickel and cobalt smelting technology in China was forecasted.
