本研究使用的低品位红土镍矿，通过工业化回转窑选择性还原和磁选，成功地提纯了低品位红土镍矿。结果表明，铁的金属化程度与镍的金属化程度均呈明显的线性相关。此外，合理的焙烧温度和延长磨矿时间可以提高还原红土镍矿的整体细度水平。适宜的焙烧温度范围为1100~1150℃，可使全镍转化为金属镍，部分抑制全铁的转化。最终从含镍1.92%的低品位红土镍矿中成功地制备出镍含量为7.32%、铁含量为84.15%的镍铁合金。镍和铁的回收率分别为96.72%和89.08%，实现了低品位红土镍矿中铁和镍的高效回收利用。
The low-grade nickel laterite ore used in this study was successfully upgraded through selective reduction by industrialized rotary kilns followed by magnetic separation. The results indicated that both iron metallization extent and nickel metallization extent showed obvious linear correlation. In addition, rational roasting temperature and prolonged grinding time could enhance the overall fineness level of reduced laterite nickel ore. The moderate roasting temperature at a range of 1100–1150 °C should be suitable enough to a conversion of total nickel to metallic nickel and partly inhibited the conversion of total iron. Ultimately, the obtained ferronickel alloy with a nickel content of 7.32% and an iron content of 84.15% was prepared successfully from the low-grade nickel laterite ore containing a nickel content of 1.92%. Nickel and iron recoveries were 96.72 and 89.08% respectively, which achieved the highly efficient recovery and utilization of iron and nickel from low-grade laterite nickel ore.
