One group of materials that are known for their wide range of applications in various arenas of the present world are the ‘ferrous materials’, which accounts for the reason of their huge demand and high-scale production, whereas on the contrary, the manufacturing of such iron-bearing materials, such as steel, cast iron, ferroalloys, and so on, has certain disadvantages, in particular, energy intensive processes, greenhouse gas emissions especially CO₂, and exhaustive utilization of natural resources. Materials on reaching their end of life are discarded as wastes which have formed a global concern and thus gaining worldwide attention for their reutilization by recycling and resource recovery. This paper provides a brief description of availability of various secondary ferrous and carbon resources, which can be effectively used for synthesizing value-added iron-bearing materials through development of efficient recycling and reformation processes and thus benefitting the environment and relevant industries.

一类以其在当今世界各个领域的广泛应用而著称的材料是“黑色金属材料”，这是由于其巨大的需求和大规模生产的原因，而相反，这种含铁材料，例如钢，铸铁，铁合金等，具有某些缺点，特别是能源密集型过程，温室气体排放，尤其是CO ₂，并充分利用自然资源。即将达到使用寿命的材料被当作废物丢弃，这已成为全球关注的问题，因此通过回收利用和资源回收再利用而受到全世界的关注。本文简要介绍了各种次级铁和碳资源的可利用性，这些资源可通过开发有效的循环利用和重整工艺而有效地用于合成增值含铁材料，从而造福于环境和相关行业。
