摘要

系统地研究了腐泥岩与褐铁矿混合半熔融冶炼工艺,深入分析了矿渣碱度的影响。结果表明,当矿渣碱度保持在0.3,褐煤红土质量分数不低于10%时,渣系可位于低熔点辉石(CaMgSi2O6)的液相区;当还原温度为1300℃、C/O质量比为0.86、褐铁矿质量分数为20%、炉渣碱度为0.3时,可制得镍品位为6.42%、铁品位为86.99%的镍铁产品。镍和铁的回收率分别达到88.60%和72.25%。

Effect of slag basicity on semi-molten smelting process of saprolitic and limonitic laterite ores
The semi-molten smelting process of a mixture of saprolitic and limonitic laterite ores was systematically investigated and the effect of slag basicity was deeply analyzed. The results indicate that the slag system can be located in the liquidus region of low melting-point diopside (CaMgSi2O6) when slag basicity is kept at 0.3 and limonitic laterite mass fraction is not less than 10%. When the reduction temperature, C/O mass ratio, limonitic laterite mass fraction and slag basicity are kept at the optimum values of 1300 °C, 0.86, 20% and 0.3, respectively, ferronickel products with grades 6.42% Ni and 86.99% Fe are prepared. The recovery rates of Ni and Fe reach 88.60% and 72.25%, respectively.

期刊介绍: The Transactions of Nonferrous Metals Society of China (Trans. Nonferrous Met. Soc. China), founded in 1991 and sponsored by The Nonferrous Metals Society of China, is published monthly now and mainly contains reports of original research which reflect the new progresses in the field of nonferrous metals science and technology, including mineral processing, extraction metallurgy, metallic materials and heat treatments, metal working, physical metallurgy, powder metallurgy, with the emphasis on fundamental science. It is the unique preeminent publication in English for scientists, engineers, under/post-graduates on the field of nonferrous metals industry. This journal is covered by many famous abstract/index systems and databases such as SCI Expanded, Ei Compendex Plus, INSPEC, CA, METADEX, AJ and JICST.
