火法冶炼红土镍矿工艺为当前从红土镍矿中提镍的主要流程。分析了主要的火法冶炼红土镍矿工艺的技术特点。火法冶炼红土镍矿工艺具有工艺成熟、流程短、效率高等优点,但同时也存在能耗较高、熔炼过程渣量过多、有粉尘污染等不足。中国自主开发了高炉冶炼红土矿生产镍铁合金新技术,并在实践中进一步得到发展,高炉冶炼红土矿生产镍铁合金工艺还应从大型化、节能、环保、长寿等领域进一步发展。当前对火法冶炼红土镍矿工艺的研究势在必行,需要在完善还原熔炼工艺方面进行深入的研究,通过研究新方法、新工艺解决火法冶炼工艺中能耗高、各种有价值金属综合回收的难题,实现红土镍矿火法冶炼工艺的低能耗、低排放和镍工业的可持续发展。
The pyrometallurgical laterite nickel ore process is the main process of extracting nickel from laterite nickel ore. The technical characteristics of the main pyrometallurgite lateritic nickel ore process are analyzed. The pyrometallurgy nickel laterite ore technology has the advantages of mature technology, short process and high efficiency, but also has the disadvantages of high energy consumption, too much slag in the smelting process and dust pollution. China independently developed new technology for producing nickel-iron alloy from laterite smelting laterite ore and further developed in practice. The production of nickel-iron alloy from laterite smelting laterite ore should be further developed from the aspects of large-scale, energy saving, environmental protection and longevity. At present, the research on pyrometallurgy laterite nickel ore process is imperative, and it is necessary to do a thorough research in the process of perfecting reduction smelting. By studying new methods and new processes to solve the problems of high energy consumption, various valuable metals Comprehensive recovery of the problem, to achieve laterite nickel ore pyrometallurgical process of low energy consumption, low emissions and sustainable development of nickel industry.
