Ferronickel slag (FNS) is a solid waste produced in the smelting of ferronickel alloys. FNS is classified as blast furnace ferronickel slag (BFS) and electric furnace ferronickel slag (EFS). They are useful in many fields, such as metal recovery and glass manufacturing. In fact, replacing cement or concrete aggregate is the best way to achieve large-scale resource recycling of FNS, while generating environmental and economic benefits, which is consistent with the concept of sustainable development. This paper summarizes the research papers of FNS as supplementary cementitious materials (SCMs), aggregates and precursors and comprehensively analyses of the sustainable utilization of FNS. The results suggest that BFS is suitable for use as SCMs with small replacement and relatively high activity, but it needs to be ground to 400–500 m²/kg. EFS is suitable for use as aggregate due to its high discharge and strong interlocking ability of particles. The influence of FNS on the performance of geopolymer concrete is mainly related to the types of precursor and activator. Combined with the results of this paper, the research direction of further improving the recycling efficiency and cleaner production of FNS is given.

镍铁渣（FNS）是镍铁合金冶炼过程中产生的固体废物。FNS分为高炉镍铁渣（BFS）和电炉镍铁渣（EFS）。它们在许多领域都很有用，例如金属回收和玻璃制造。事实上，替代水泥或混凝土骨料是实现FNS大规模资源循环利用的最佳途径，同时产生环境和经济效益，符合可持续发展理念。本文总结了FNS作为辅助胶凝材料（SCMs）、骨料和前驱体的研究论文，综合分析了FNS的可持续利用。结果表明，BFS适合用作替代量小、活性较高的SCM，但需要研磨至400-500 m^2个/公斤。EFS的排量高，颗粒互锁能力强，适合做骨料使用。FNS对地聚物混凝土性能的影响主要与前驱体和活化剂的种类有关。结合本文的研究结果，给出了进一步提高FNS回收利用效率和清洁生产的研究方向。
