Research Progress on Preparation of Mineral Materials from Iron Tailings
In order to promote the process of"emission peak and carbon neutrality"and practice the concept of solid waste resource utilization,the reuse of iron tailings resources has become one of the key issues that need to be solved urgently.Based on the similarity of iron tailings and natural sand composition,the research on the materialization of iron tailings resources was carried out.The technical methods and technological processes of preparing concrete,ceramic materials,thermal insulation materials,unfired bricks,glass-ceramics,coatings and other mineral materials by iron tailings were introduced in detail.The superiority and application value of different types of composite mineral materials prepared by iron tailings were analyzed and expounded.The results show that the future research on the preparation of mineral materials from iron tailings can focus on the following research directions.Firstly,construction and improvement of deep processing system of iron tailings.Secondly,exploration of new technology and new method of iron tailings materialization.Thirdly,study on the mechanism of active fiber in tailings materialization.Fourthly,establishment of matching information system and parameter optimization model for iron tailings properties and utilization technology.The research results can provide an effective way to realize the material utilization of iron tailings,promote the efficient resource utilization of iron tailings,and realize the organic unity of economic value and social benefit.
