磷尾矿资源化利用研究进展
Research progress on resource utilization of phosphate tailings
摘要
Abstract
Phosphate tailings are the primary solid waste generated during the phosphate rock flotation process and contain abundant valuable components.Nevertheless,restricted by their physicochemical inertness,the overall comprehensive utilization rate remains relatively low.Against the backdrop of the dual carbon goal and green mine construction,exploring low-carbon and high-efficiency utilization approaches for phosphate tailings is critical to alleviating the pressure of phosphorus resource exploitation in China and balancing ecological and economic benefits.Utilization approaches of phosphate tailings are mainly divided into four categories:extraction and recovery of valuable elements;preparation of building materials;backfilling of mine goafs;and application as soil amendments,fertilizers or water retaining agents in agriculture.However,existing technologies still suffer from high energy consumption,difficulty in balancing cost and material performance,and low added value of products.Future research should prioritize development of clean high-value utilization and collaborative disposal of multiple solid wastes,and make breakthroughs in low-cost and low-energy-consumption activation and cascade separation technologies.Meanwhile,it is necessary to improve the evaluation mechanism of environmental safety and ecological risks,guarantee long-term stability of the utilization system,promote large-scale disposal and comprehensive full-quantity utilization of phosphate tailings,and realize ecological environment protection and sustainable utilization of resources.关键词
